Product <br />2.1 <br />Information about the enterprise <br />EFCA (European Federation of Concrete Admixtures <br />Associations) was formed in 1984 as a partnership <br />between national admixture associations in order to <br />promote the interests of the industry at European level. <br />For more information (such as membershiplist) see: <br />www.efca.info</p> <p>2</p> <p>2.2 <br />Product description/Product definition <br />Admixtures are liquid or powdery agents that are <br />introduced in small amounts (< 5% by mass of the <br />cement content) to concrete while it is being mixed and <br />that enhance the properties of the fresh and/or <br />hardened concrete. <br />Retarders are admixtures that extend the time to the <br />mixture’s transition from the plastic to the hardened <br />state.</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Retarders</p> <p>The results of the Life Cycle Assessment provided in <br />this declaration have been selected from the product <br />with the highest environmental impact (worst-case <br />scenario). <br />The product needs a declaration of performance <br />taking into consideration EN 934-2:2009+A1:2012, <br />Admixtures for concrete, mortar and grout – Part 2: <br />Concrete admixtures – Definitions, requirements, <br />conformity, marking and labelling and the CE-marking. <br />For the application and use the respective national <br />provisions apply. <br />2.3 <br />Application <br />Concrete admixtures are used as constituent materials <br />for the production of concrete, mortar and grout <br />(unreinforced concrete, reinforced and prestressed <br />concrete, site-mixed and ready-mixed concrete, <br />precast concrete). Their application should be in line <br />with the manufacturer’s technical documents and <br />Declaration of Performance. <br />2.4 <br />Technical Data <br />Retarders must comply with the general requirements <br />of EN 934-1:2008 and the additional requirements of <br />EN 934-2:2009+A1:2012. <br />The corresponding requirements in line with /EN 9341:2008/ and /EN 934-2:2009+A1:2012/ must be <br />maintained. <br />Constructional data <br />Name</p> <p>Density /ISO 758/ <br />Solids content /EN 480-8/ <br />pH value /ISO 4316/</p> <p>Chloride content /EN 480-10/</p> <p>Alkali content /EN 480-12/</p> <p>Corrosion behavior /EN 934-1/, <br />/EN 480-14/ <br />SiO2 content /EN 192-2/</p> <p>Value</p> <p>Unit</p> <p>1 - 1.6 <br />g/ml <br />-¹ <br />M.-% <br />-¹ <br />-log10(aH+) <br />Maximum <br />value to be <br />declared <br />M.-% <br />by the <br />manufactur <br />er <br />Maximum <br />value to be <br />declared <br />M.-% <br />by the <br />manufactur <br />er <br />-²</p> <p>μ A/cm2</p> <p>-³ <br />M.-% <br />Test mix ≤ <br />2% volume <br />above <br />control mix <br />Air content of fresh concrete /EN <br />unless <br />Vol.-% <br />12350-7/ <br />stated <br />otherwise <br />by the <br />manufactur <br />er <br />At 7 days: <br />test mix ≥ <br />80% of <br />Compressive strength /EN 12390- control mix <br />N/mm2 <br />At 28 days: <br />3/ <br />test mix ≥ <br />90% of <br />control mix <br />Water reduction /EN 12350-2/, <br />-⁴ <br />mm <br />/EN 12350-5/ Plasticizer <br />Increasing / maintaining of <br />-⁴ <br />mm <br />3</p> <p>consistence /EN 12350-2/, /EN <br />12350-5/ Superplasticizer</p> <p>Setting time /EN 480-2/ <br />Accelerator/Retarder</p> <p>Start: test <br />mix ≥ <br />control mix <br />+ 90 min. <br />End: test <br />mix ≤ <br />control mix <br />+ 360 min.</p> <p>min</p> <p>Air void Characteristics in <br />hardened concrete /EN 480-11/ <br />-⁴ <br />mm <br />Air entrainer <br />Capillary water absorption /EN <br />-⁴ <br />g/mm2 <br />480-5/ Densifier <br />¹ Value will be made available to user on request <br />² No corrosion behaviour test is required for admixtures <br />which only contain active substances in the list of <br />approved substances to EN 934-1, Annexe A.1 and in <br />the list of declared substances to EN 934-1, Annexe <br />A.2. <br />³ Maximum value must only be indicated when SiO2 <br />percentage by mass > 5 % <br />⁴ Details not relevant for this type of admixture</p> <p>Performance data of the product in accordance with <br />the declaration of performance with respect to its <br />essential characteristics according to EN 9342:2009+A1:2012, Admixtures for concrete, mortar and <br />grout – Part 2: Concrete admixtures – Definitions, <br />requirements, conformity, marking and labelling. <br />2.5 <br />Delivery status <br />Retarders are usually supplied in liquid, paste or <br />powder form in containers made of steel or plastic. <br />Typical container sizes are canisters containing <br />approx. 25 kg, drums with approx. 200 kg or <br />Intermediate Bulk Containers (IBC) with 1000 kg. The <br />containers are shipped on wooden pallets. <br />For larger applications, loose deliveries in tank trucks <br />with a capacity in excess of 1 tonne are also used. <br />2.6 <br />Base materials/Ancillary materials <br />The raw materials most frequently used for retarders <br />are: sucrose, gluconates, phosphates, and lignin <br />sulphonates. <br />Preservatives are added as minor components and <br />auxiliaries. <br />Retarders are aqueous solutions of the raw materials <br />or mixes of the raw materials referred to above. Active <br />substance concentration lies between 10 and 30% by <br />mass. The typical dosage of retarders lies between 0.2 <br />and 2.0% by mass in relation to the cement weight. <br />The products covered by this EPD typically contain the <br />following proportions by mass of constituent materials <br />and auxiliaries referred to: <br />Sucrose*: <br />max. 35 % <br />Gluconates*: <br />max. 45 % <br />Phosphates*: <br />max. 60 % <br />Lignin sulphonates*: <br />max. 40 % <br />Phosphonic acid*: <br />max. 10 % <br />Tetrapotassium pyrophosphate <br />max. 30 % <br />Additives: <br />max. 0.2 % <br />Water: <br />approx. 40 - 98 % <br />*Solid content <br />These volumes are average values and the <br />composition of products complying with the EPD can</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Retarders</p> <p>deviate from these concentration levels in individual <br />cases. <br />Note: For companies to declare their products within <br />the scope of this EPD it is not sufficient to simply <br />comply with the product composition shown above. <br />The application of this EPD is only possible for <br />member companies of EFCA’s member associations <br />and only for specific formulations with a total score <br />below the declared maximum score for a product <br />group according to the associated guidance document. <br />Concrete admixtures – Retarders are mixtures under <br />the chemical legislation (REACH and Classification, <br />Labelling and Packaging CLP). <br />1. substances from the “Candidate List of <br />Substances of Very High Concern for Authorisation” <br />(SVHC) <br />If this product contains substances listed in the <br />candidate list (latest version) exceeding 0.1 <br />percentage by mass, the relevant information can be <br />found in the safety data sheet of the relevant product <br />covered by this model EPD <br />If the construction product (concrete admixture Retarders) contains SVHC exceeding 0.1 percentage <br />by mass, the respective SVHC, its CAS number, <br />information on the concentration and / or concentration <br />range together with information on their hazardous <br />properties are listed in the safety data sheet of the <br />respective product. <br />2. CMR substances in categories 1A and 1B <br />If this product contains other carcinogenic, mutagenic, <br />reprotoxic (CMR) substances in categories 1A or 1B <br />which are not on the candidate list, exceeding 0.1 <br />percentage by mass, the relevant information can be <br />found in the safety data sheet of the relevant product <br />covered by this model EPD. <br />If the construction product (concrete admixture Retarders) contains CMR substances in categories 1A <br />or 1B exceeding 0.1 percentage by mass, the <br />respective CMR substances, information on the <br />concentration and/or concentration range together with <br />information on their hazardous properties are listed in <br />the safety data sheet of the respective product. <br />3. Biocide products added to the construction product <br />Biocide products were added to this construction <br />product, or it has been treated with biocide products <br />(this then concerns a treated product as defined by the <br />(EU) Ordinance on Biocide Products No. 528/2012)</p> <p>2.7 <br />Manufacture <br />Concrete admixtures are usually manufactured by <br />mixing ingredients together in batch mode and filling <br />containers for dispatch. The process follows quality <br />standards outlined in EN 934-6:2019. <br />2.8</p> <p>Environment and health during <br />manufacturing <br />As a general rule, no environmental or health <br />protection measures other than those specified by law <br />are necessary. <br />2.9 <br />Product processing/Installation <br />During concrete manufacture, concrete admixtures are <br />usually added along with the mixing water or included <br />in premixed concrete. <br />Health and safety measures (eye protection, hand <br />protection, possibly respiratory equipment and body <br />protection) are to be taken and consistently adhered to <br />in accordance with the information on the safety data <br />sheet and conditions on site. <br />2.10 Packaging <br />Reusable containers are, where practicable taken back <br />by the manufacturer and redirected into the production <br />circuit. Empty plastic or steel containers which can no <br />longer be used are recyclable. <br />Wooden reusable pallets are, where practicable taken <br />back by the manufacturer or building material trader <br />who returns them to the building product manufacturer <br />redirecting them into the production process. <br />2.11 Condition of use <br />During the use phase, concrete admixtures are firmly <br />bound into the cement matrix in hardened concrete. <br />Concrete admixtures make an essential contribution <br />towards optimizing the physical and chemical <br />properties of concrete enhancing its performance, <br />durability, economic value and sustainability. <br />2.12 Environment and health during use <br />During the use phase, concrete admixtures are firmly <br />bound into the cement matrix in hardened concrete. <br />No relevant risks are known for water, air and soil if the <br />products are used as designated. <br />2.13 Reference service life <br />Not relevant as this declaration relates to a preliminary <br />product. <br />2.14</p> <p>Extraordinary effects</p> <p>Usually the construction product (concrete admixture Retarders) contain small amounts (< 0.5% by mass) of <br />biocides of the product type “in-can preservatives”.</p> <p>Fire <br />Not relevant as this declaration relates to a preliminary <br />product.</p> <p>The information which active substances are contained <br />in the product can be found in the safety data sheet of <br />the relevant product covered by this model EPD.</p> <p>Fire protection <br />Not relevant as this declaration relates to a preliminary <br />product .</p> <p>If the construction product (concrete admixture Retarders) contains biocide products, the active <br />substances, information on the concentration and/or <br />concentration range, the product type together with <br />information on their hazardous properties are listed in <br />the safety data sheet of the respective product.</p> <p>Water <br />Not relevant as this declaration relates to a preliminary <br />product.</p> <p>4</p> <p>Mechanical destruction</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Retarders</p> <p>Not relevant as this declaration relates to a preliminary <br />product. <br />2.15 Re-use phase <br />Not relevant as this declaration relates to a preliminary <br />product. <br />2.16 Disposal <br />Empty, dried containers are directed to the recycling <br />process where practicable. <br />Packaging residue must be directed to proper waste <br />disposal taking local guidelines into consideration. <br />Admixture residues, during the installation phase into <br />the building, are directed to landfill. Admixture applied</p> <p>into the building and dismantled at the end of the <br />product service life cannot be separated anymore from <br />concrete. For this reason, this admixture is sent <br />directly to landfill along with concrete. The European <br />Waste Code (EWC) applicable for the declared product <br />can be assimilated to the concrete EWC 170101. <br />2.17 Further information <br />More information is available in the manufacturers' <br />product or safety data sheets on the manufacturers' <br />Web sites or on request. <br />An electronic version of this declaration is available at <br />www.efca.info and www.ibu-epd.com</p> <p>3. LCA: Calculation rules <br />3.1 <br />Declared Unit <br />This EPD refers to the declared unit of 1 kg concrete <br />admixture applied into the building with a density of 11.6 kg/l in accordance with the IBU PCR 11.2017 Part <br />B for concrete admixtures. <br />The maximum dosage of Retarders is 2% by mass <br />related to the cement content in the concrete. <br />The results of the Life Cycle Assessment provided in <br />this declaration have been selected from the product <br />with the highest environmental impact (worst-case <br />scenario). <br />Depending on the application, a corresponding <br />conversion factor such as the density to convert <br />volumetric use to mass must be taken into <br />consideration. <br />The Declaration type is according to EN 15804+A2: <br />Cradle to gate with options, modules C1–C4, and <br />module D</p> <p>during the incineration of wastes in module A5, which <br />are declared in module D. <br />3.3 <br />Estimates and assumptions <br />For this EPD formulation and production data <br />defined by EFCA were considered. Production waste <br />was assumed to be disposed of to landfill without <br />credits as a worst case. <br />An average of plastic containers and wooden pallets <br />was considered in the LCA. <br />3.4 <br />Cut-off criteria <br />All raw materials submitted for the formulations and <br />production data were taken into consideration. <br />The manufacture of machinery, plant and other <br />infrastructure required for production of the products <br />under review was not taken into consideration in the <br />LCA. <br />Transport of packaging materials is excluded.</p> <p>Declared unit <br />Name</p> <p>Value</p> <p>Unit</p> <p>Declared unit</p> <p>1 <br />1000 1600 <br />-</p> <p>kg</p> <p>Gross density <br />Conversion factor to 1 kg</p> <p>kg/m3 <br />-</p> <p>3.2 <br />System boundary <br />Modules A1, A2 and A3 are taken into consideration in <br />the LCA: <br />- A1 Production of preliminary products <br />- A2 Transport to the plant <br />- A3 Production incl. provision of energy, production of <br />packaging as well as auxiliaries and consumables and <br />waste treatment <br />-A5 Installation, admixtures applied into the building <br />during A5 phase operations and packaging disposal. <br />-C1-C2-C4-D <br />The building deconstruction (demolition process) takes <br />place in C1 module which considers energy production <br />and consumption in terms of diesel and all the <br />emissions connected with the fuel-burning process. <br />After the demolition, admixture is transported to the <br />end-of-life processing (C2 module) where all the <br />impacts related to the transport processes are <br />considered. For precautionary principle and as worstcase scenario, disposal is the only end of life scenario <br />considered. This is modelled by landfill process <br />(module C4) where admixtures end their life cycle. <br />Module D accounts for benefits that are beyond the <br />defined system boundaries. Credits are generated <br />5</p> <p>3.5 <br />Background data <br />Data from the GaBi database SP40 (2020) was used <br />as background data. <br />3.6 <br />Data quality <br />Representative products were applied for this EPD and <br />the product in the group displaying the highest <br />environmental impact was selected for calculating the <br />LCA results. The background data sets used are no <br />more than 4 years old. <br />Production data and packaging are based on details <br />provided by the manufacturer. The formulation used for <br />evaluation refers to a specific product. <br />The data quality of the background data is considered <br />to be good. <br />3.7 <br />Period under review <br />Representative formulations are valid for 2019 under <br />consideration of data from 2011.</p> <p>3.8 <br />Allocation <br />Mass allocation have been applied when primary data <br />have been used and implemented into the LCA model <br />3.9 <br />Comparability <br />Basically, a comparison or an evaluation of EPD data <br />is only possible if all the data sets to be compared <br />were created according to EN 15804 and the building</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Retarders</p> <p>context, respectively the product-specific <br />characteristics of performance, are taken into account.</p> <p>The GaBi database SP40 (2020) has been used. <br />.</p> <p>4.

LCA: Interpretation <br />When considering upstream production and transport <br />of pre-products as well as manufacturing of the <br />concrete admixture (modules A1-A3), the main driver <br />of impacts in all categories is the production of preproducts (module A1), generally more than 85 %. <br />For global warming potential (GWP) about 85 % the <br />impacts are from pre-products production processes <br />and related chemical precursors. The manufacturing <br />process is the second contributor (less than 10 % the <br />total GWP). Important contributors to this indicator <br />during the manufacturing process are electricity <br />production consumed during the admixture production <br />process (module A3) and the plastic produced and <br />consumed for final product packaging. The European <br />electricity grid mix makes a fairly important contribution <br />to impacts in the categories of eutrophication <br />freshwater (4%) and ozone depletion (15 %) , <br />renewable primary energy demand (PERT), and <br />radioactive waste, and acts as a minor contributor to <br />global warming potential (GWP). Renewable primary <br />energy demand (PERT) is influenced by electricity <br />production (about 14 %) and for the rest by preproducts production. Non-renewable primary energy <br />demand (PENRT) is influenced almost only by preproducts production (about 90 %) and electricity for 4 <br />%. Treatment of production waste has negligible <br />contribution to impacts in all categories except <br />eutrophication freshwater (10 %), where landfilling of <br />production waste has an influence. <br />The other life cycle phases have minor influence, <br />generally lower than 5%.</p> <p>A5 module: It is mainly dominated by the incineration <br />process of packaging wastes, in particular the <br />incineration of plastic (HDPE) is the main contributor <br />for all indicators followed by incineration of wood <br />packaging. This module accounts also for the calorific <br />value of the packaging considered as an output and <br />therefore with a negative value. This influence <br />PENRM, non-renewable energy content by plastic <br />packaging and PERM, renewable energy content by <br />wood packaging. <br />Considering the entire end of life modules, landfill for <br />construction wastes is the main contributor for all the <br />impact considered, followed by the truck used for <br />transporting the waste from the building site to the <br />landfill. <br />C1 module: the combustion of fuel occurring during <br />demolition processes is the main contributor for this <br />module and for all the impacts considered. <br />C2 module: trucks used for waste transport and related <br />combustion emissions are the main contributor for all <br />impacts considered. <br />C3 module: landfill process and in particular energy <br />consumed for landfill management and operation is the <br />main contributor for all the impacts considered. <br />D module: It is influenced by the credits generated <br />during implementation module (A5), thanks to the <br />energy produced by the incineration processes used <br />for packaging disposal and secondly by the <br />incineration of the admixture residue when this <br />material can be incinerated (thanks to its calorific <br />value).</p> <p>7.
