In turn, this can be used to assess the susceptibility of that concrete to <br />alkali-silica reaction (ASR). <br />8.2.3 On the basis of data assessed, the lower permeability of concrete containing the system reduces the ingress of <br />sulfates. However, if sulfate-resistant concrete is required, the advice of the Certificate holder should be sought, but <br />such advice is outside the scope of this Certificate. <br />8.2.4 Use of the system reduces the leaching of lime from the hydrated cement in concrete. <br />8.2.5 Concrete containing the system has a similar resistance to freeze/thaw to that of the equivalent plain concrete.</p> <p>BBA 20/5741 PS2 Issue 2</p> <p>Page 6 of 13</p> <p>8.2.6 Concrete containing the system has a greater resistance to carbon dioxide diffusion than the equivalent plain <br />concrete. <br />8.3 Service life <br />8.3.1 Under normal conditions of service, concrete containing the system is more durable than the equivalent plain <br />concrete, owing to its reduced permeability. <br />8.3.2 Where exposure to aggressive soil conditions or chemicals is anticipated, a full assessment of the site must be <br />made. In these situations, the Certificate holder should be consulted on the suitability of the system, but such advice is <br />outside the scope of this Certificate.</p> <p>PROCESS ASSESSMENT <br />Information provided by the Certificate holder was assessed for the following factors:</p> <p>9 Design, installation, workmanship and maintenance <br />9.1 Design <br />9.1.1 The design process was assessed by the BBA, and the following requirements apply in order to satisfy the <br />performance specified in this Certificate. <br />9.1.2 Concrete containing the system must be designed in accordance with BS EN 206 : 2013 Section 5.2.3.5 and BS <br />8500-2 : 2023 Clause 5.2, for use as all normal types, including precast, pre-stressed, post-tensioned, ready-mixed, <br />reinforced, slip-formed, sprayed and pump concretes. For additional information on required thickness of concrete, the <br />advice of the Certificate holder may be sought, but such advice is outside the scope of this Certificate. <br />9.1.3 The system is compatible with cement blends containing fly ash, ground granulated blast furnace slag and silica <br />fume, as defined in BS EN 197-1 : 2011. <br />9.1.4 Structures built incorporating the system must be designed to the relevant clauses of BS 8102 : 2022, and <br />BS EN 1992-1-1 : 2023, BS EN 1992-1-2 : 2023 and BS EN 1992-3 : 2006 and their UK National Annexes. <br />9.1.5 Concrete containing the system is suitable for Type B constructions as defined in BS 8102 : 2022, and can satisfy <br />the requirements for all grades defined in Table 2 of this Standard. For Grade 3 (where control of water vapour is <br />required), it will be necessary to provide the mix with a sufficiently low vapour permeability in combination with an <br />adequate section thickness (see section 3.1 of this Certificate). The use of suitable ventilation, dehumidification or air <br />conditioning, appropriate to the intended use, must also be considered. <br />9.1.6 The concrete must have a minimum cement content of 350 kg·m–3 and be batched with a maximum <br />water/cement ratio of 0.43. Further details of suitable mixes can be obtained from the Certificate holder or their <br />approved representatives, but such advice is outside the scope of this Certificate. <br />9.1.7 When an additional superplasticiser is required, it must be added after the addition of the system and in <br />accordance with the supplier’s recommendations. <br />9.1.8 Once the fresh concrete is mixed, further materials must not be added to the fresh concrete. <br />9.1.9 Joints must be designed with waterstops as recommended in BS 8102 : 2022, to maintain the watertightness of <br />the whole structure. The advice of the Certificate holder should be sought on particular applications. <br />9.1.10 Basements for dwellings must be designed in accordance with the guidance given in the Guidance Document — <br />Basements for dwellings(1). <br />(1) Published by the Basement Information Centre, Product code: TBIC/007.</p> <p>BBA 20/5741 PS2 Issue 2</p> <p>Page 7 of 13</p> <p>9.2 Installation <br />9.2.1 Installation instructions provided by the Certificate holder were assessed and judged to be appropriate and <br />adequate. <br />9.2.2 Installation must be carried out in accordance with this Certificate and the Certificate holder’s instructions. <br />9.2.3 Concrete containing the system must not be placed at temperatures lower than 5°C. <br />9.2.4 Concrete containing the system must be fully compacted. <br />9.2.5 The concrete must be cured strictly in accordance with BS EN 13670 : 2009, and BS EN 1992-1-1 : 2023 and its UK <br />National Annex, and the Certificate holder’s instructions. <br />9.2.6 Penetrations of the concrete, such as pipe entries or formwork ties, must also be securely sealed to maintain <br />watertightness. The advice of the Certificate holder must be sought on suitable materials for this purpose, but such <br />advice and products are outside the scope of this Certificate. <br />9.3 Workmanship <br />Practicability of installation was assessed, on the basis of the Certificate holder’s information. To achieve the <br />performance described in this Certificate, concrete containing the system must be placed, compacted and cured by <br />operatives with experience of using conventional concreting methods and equipment. <br />9.4 Maintenance and repair <br />For a specific installation, the maintenance regime should be considered to ensure that the required design life of the <br />concrete is achieved.</p> <p>10 Manufacture <br />10.1 The production processes for the system have been assessed, and provide assurance that the quality controls are <br />satisfactory according to the following factors: <br />10.1.1 The manufacturer has provided documented information on the materials, processes, testing and control <br />factors. <br />10.1.2 The quality control operated over batches of incoming materials has been assessed and deemed appropriate <br />and adequate. <br />10.1.3 The quality control procedures and system testing to be undertaken have been assessed and deemed <br />appropriate and adequate. <br />10.1.4 The process for management of non-conformities has been assessed and deemed appropriate and adequate. <br />10.1.5 An audit of each production location was undertaken, and it was confirmed that the production process was in <br />accordance with the documented process, and that equipment has been properly tested and calibrated. <br />† 10.2 The BBA has undertaken to review the above measures on a regular basis through a surveillance process, to <br />verify that the specifications and quality control operated by the manufacturer are being maintained.</p> <p>BBA 20/5741 PS2 Issue 2</p> <p>Page 8 of 13</p> <p>11 Delivery and site handling <br />11.1 The Certificate holder stated that the system is supplied in various packaging formats as given in Table 6. <br />Table 6 Product packaging <br />Nominal weight <br />3 kg <br />17 kg <br />700 kg</p> <p>Packaging type <br />Water-soluble bag <br />Plastic bag <br />Plastic bag</p> <p>No. per pallet <br />192 <br />48 <br />1</p> <p>Estimated total weight of pallet <br />600 kg <br />840 kg <br />724 kg</p> <p>11.2 Each container bears the Certificate holder’s name, system name, batch number, health and safety information, <br />CE mark and the BBA logo incorporating the number of this Certificate. <br />11.3 Delivery and site handing must be performed in accordance with the Certificate holder’s instructions and this <br />Certificate, including: <br />11.3.1 The system must be stored in its original sealed containers in a cool, dry environment, protected from sunlight <br />at temperatures between 5 and 35°C. <br />11.3.2 When handling, the normal health and safety procedures associated with cementitious materials must be <br />observed.</p> <p>BBA 20/5741 PS2 Issue 2</p> <p>Page 9 of 13</p> <p>†ANNEX A – SUPPLEMENTARY INFORMATION <br />Supporting information in this Annex is relevant to the system but has not formed part of the material assessed for the <br />Certificate.</p> <p>Construction (Design and Management) Regulations 2015 <br />Construction (Design and Management) Regulations (Northern Ireland) 2016 <br />Information in this Certificate may assist the client, designer (including Principal Designer) and contractor (including <br />Principal Contractor) to address their obligations under these Regulations.</p> <p>CLP Regulations <br />The Certificate holder has taken the responsibility of classifying and labelling the system components under the GB CLP <br />Regulation and CLP Regulation (EC) No 1272/2008 - classification, labelling and packaging of substances and mixtures. <br />Users must refer to the relevant Safety Data Sheet(s).</p> <p>CE marking <br />The Certificate holder has taken the responsibility of CE marking the system in accordance with harmonised European <br />Standard EN 934-2 : 2009, Table 9.</p> <p>Management Systems Certification for production <br />The management system of the manufacturer has been assessed and registered as meeting the requirements of BS EN <br />ISO 9001 : 2015 by TÜV Rheinland Cert GmbH (Certificate 01 100 6383/05).</p> <p>Additional information on installation <br />Mix design <br />A.1 Concrete containing the system is normally supplied as ready-mixed concrete but may be prepared on site where <br />there is adequate mix control(1).
