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 />Primarily salts of higher fatty acids serve as raw <br />materials for water-resisting admixtures, supplied as <br />aqueous dispersions. Dispersions of higher fatty acids <br />as well as emulsions containing silanes or siloxanes as <br />active agents are also used. Dispersions of calcium <br />stearate in water are the most common water-resisting <br />admixtures. Defoaming agents, emulsifying agents and <br />preservatives are added as minor components and <br />auxiliaries for water-resisting admixtures. <br />The active agent concentration of the calcium stearate <br />most frequently used lies between 20 and 50 <br />percentage by mass. The typical dosage of waterresisting admixtures lies between 0.5 and 1.0 <br />percentage by mass in relation to the cement weight.</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Water Resisting Admixtures</p> <p>The products covered by this EPD typically contain the <br />following proportions by mass of constituent materials <br />and auxiliaries referred to: <br />Silanes/Siloxanes*: <br />max. 50 % <br />Calcium stearate*: <br />max. 50 % <br />Salts of higher fatty acids*: <br />max. 20 % <br />Ethanolamine <br />max. 5 % <br />Additives: <br />max. 0.2 % <br />Water <br />approx. 50 - 85 % <br />*Solid content <br />These volumes are average values and the <br />composition of products complying with the EPD can <br />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 – Water Resisting are mixtures <br />under the chemical legislation (REACH and <br />Classification, Labelling and Packaging CLP). <br />1. substances from the “Candidate List of <br />Substances of Very High Concern for <br />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 - Water <br />Resisting) 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 - Water <br />Resisting) 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 <br />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>4</p> <p>Usually the construction product (concrete admixture Water Resisting) contain small amounts (< 0.5% by <br />mass) of biocides of the product type “in-can <br />preservatives”. <br />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. <br />If the construction product (concrete admixture Water <br />Resisting) 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. <br />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.</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Water Resisting Admixtures</p> <p>2.14</p> <p>Extraordinary effects</p> <p>Fire <br />Not relevant as this declaration relates to a preliminary <br />product. <br />Fire protection <br />Not relevant as this declaration relates to a preliminary <br />product . <br />Water <br />Not relevant as this declaration relates to a preliminary <br />product. <br />Mechanical destruction <br />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.</p> <p>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 <br />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 <br />0,9-1.6 kg/l in accordance with the PCR Part B for <br />concrete admixtures. <br />The maximum dosage of Water Resisting Admixtures <br />is 1% by mass related to the cement content in the <br />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: Cradle <br />to gate with options, modules C1–C4, and module D <br />Declared unit <br />Name</p> <p>Declared unit <br />Gross density <br />Conversion factor to 1 kg</p> <p>Value</p> <p>Unit</p> <p>1 <br />900 - 1600 <br />-</p> <p>kg <br />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 />5</p> <p>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 />during incineration of wastes in module A5, which are <br />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. <br />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.</p> <p>Environmental Product Declaration EFCA – Concrete admixtures – Water Resisting Admixtures</p> <p>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. <br />3.8 <br />Allocation <br />Mass allocation have been applied when primary data <br />have been used and implemented into the LCA model.</p> <p>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 <br />context, respectively the product-specific <br />characteristics of performance, are taken into account. <br />The GaBi database SP40 (2020) has been used. .</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) which is more than 85 % for <br />almost all indicators. <br />For global warming potential (GWP) about 86 % 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 % of <br />the 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 consumed for final <br />product packaging. The European electricity grid mix <br />plays a minor role in defining ozone depletion potential <br />impact and radioactive waste, and also has a minor <br />influence on eutrophication freshwater. The plastic <br />packaging of the concrete admixture has some <br />influence on results in the category of photochemical <br />ozone creation (5 %)and ozone depletion (5 %) and <br />global warming potential (5 %). Renewable primary <br />energy demand has a small contribution from <br />electricity production during the manufacturing phase <br />(about 5 %) and non-renewable primary energy has a <br />minor contribution from packaging (8 %). Treatment of <br />production waste has negligible contribution to impacts <br />in all categories with the exception of eutrophication <br />freshwater, where landfilling of production waste <br />contributes mainly. <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.
