The permeability of concrete is strongly dependent on the exact mix design, and the figures <br />given in section 7.2 indicate the levels that can be obtained using the product. <br />7.4 The appropriate thickness for concrete with a specific permeability to achieve a water vapour resistance of 200 or <br />500 MN∙sg-1(1) (suitable for grade 3 to BS 8102 : 2009) is given by: <br />For 200 MN∙sg-1, t=0.2 x 1012 x p <br />For 500 MN∙sg-1, t=0.55 x 1012 x p <br />where: <br />t <br />p</p> <p>is the concrete thickness in mm <br />is the water vapour permeability in g∙m(N∙s)-1 (from tests to BS 3177 : 1959).</p> <p>(1) This figure may be used where a high resistance to water vapour is required.</p> <p>8 Reinforcement protection <br />8.1 The high level of alkalinity required to prevent corrosion of the reinforcement (pH > 13) will not be adversely <br />affected by the incorporation of the product in the concrete. <br />8.2 Corrosion of the reinforcement is normally caused by the ingress of chloride to the steel or by the reduction in <br />alkalinity of the concrete by the diffusion of carbon dioxide. The reduced permeability of concrete containing the <br />product will slow down diffusion of aggressive agents into the concrete and so provide improved protection against <br />reinforcement corrosion. <br />8.3 The Certificate holder has declared the chloride ion content of the product as <0.1%. <br />8.4 The Certificate holder has declared that the product complies with the corrosion behaviour requirements given in <br />BS EN 934-1 : 2008, Clause 5.1, and is labelled accordingly.</p> <p>9 Mechanical properties <br />The compressive strength, flexural strength and static modulus of elasticity of concrete containing the product is similar <br />to that of the equivalent plain concrete. <br />Page 4 of 9</p> <p>10 Drying shrinkage and wetting expansion <br />10.1 The drying shrinkage and wetting expansion of concrete containing the product is reduced compared with that of <br />the equivalent plain concrete. <br />10.2 Tests conducted on concrete containing the product showed a drying shrinkage(1) of 0.034% compared with <br />0.046% for control concrete, and a wetting expansion(1) of 0.020 % compared with 0.021% for control concrete. <br />(1) The specific effect of the product on these properties for a particular mix and site conditions should be evaluated through site trial prior to use.</p> <p>11 Setting characteristics and hardening <br />11.1 The effect of the product for a specific mix and site conditions should be evaluated through site trials prior to use. <br />11.2 The setting time of concrete mixes containing the product will be similar to an equivalent plain concrete. The <br />setting time will depend on the concrete mix design used and the ambient temperature during placing and curing.</p> <p>12 Carbonation resistance <br />Concrete containing the product has greater resistance to carbon dioxide diffusion than the equivalent plain concrete.</p> <p>13 Frost resistance <br />Concrete containing the product has similar resistance to freeze/thaw to that of the equivalent plain concrete.</p> <p>14 Sulfate resistance <br />The lower permeability of concrete containing the product will reduce the ingress of sulfates. However, if sulfateresistant concrete is required, the advice of the Certificate holder should be sought.</p> <p>15 Alkali silica reaction (ASR) <br />15.1 Concrete containing the product should be designed in accordance with BS EN 206 : 2013 Section 5.2.3.5 and <br />BS 8500-2 : 2015 Clause 5.2. <br />15.2 The sodium oxide equivalent of the product, when measured in accordance with BS EN 480-12 : 2005, was 1.11% <br />by mass of admixture. The Certificate holder’s declared value of ≤8.5 % should be used when calculating the <br />contribution of the product to the total alkali content of a given concrete mix. In turn, this can be used to assess the <br />susceptibility of that concrete to alkali-silica reaction.</p> <p>16 Resistance to leaching <br />Use of the product will reduce the leaching of lime from the hydrated cement in concrete.</p> <p>17 Maintenance <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>18 Durability <br />18.1 Under normal conditions of service, concrete containing the product is more durable than the equivalent plain <br />concrete, owing to its reduced permeability. <br />18.2 Where exposure to aggressive soil conditions or chemicals is anticipated, a full assessment of the site should be <br />made. In these situations, the Certificate holder should be consulted on the suitability of the product. <br />Page 5 of 9</p> <p>Installation <br />19 General <br />19.1 When used in concrete mixes, the product enhances durability and improves protection against reinforcement <br />corrosion by providing the concrete with reduced permeability that protects against water ingress via absorption and <br />hydrostatic pressure. <br />19.2 The use of the product will produce a concrete with the following properties relative to a control: <br />• <br />• <br />• <br />•</p> <p>reduced porosity <br />reduced permeability <br />increased water resistance <br />increased corrosion resistance.</p> <p>19.3 The product has no known detrimental effect on the properties of concrete. <br />19.4 Structures built incorporating the product should be designed to the relevant clauses of BS 8102 : 2009, and <br />BS EN 1992-1-1 : 2004, BS EN 1992-1-2 : 2004 and BS EN 1992-3 : 2006 and their UK National Annexes. <br />19.5 The product is suitable for Type B constructions as defined in BS 8102 : 2009, and can satisfy the requirements for <br />all grades defined in Table 2 of this Standard. For Grade 3 (where control of water vapour is required), it will be <br />necessary to provide the mix with a sufficiently low vapour permeability in combination with an adequate section <br />thickness (see sections 7.2 and 7.3). The use of suitable ventilation, dehumidification or air conditioning, appropriate to <br />the intended use, must also be considered. <br />19.6 Basements for dwellings should be designed in accordance with the guidance given in the Guidance Document — <br />Basements for dwellings(1). <br />(1) Published by Basement Information Centre, Product code: TBIC/007.</p> <p>20 Mix design <br />20.1 Concrete containing the product is normally supplied as ready-mixed concrete but may be prepared on sites <br />where there is adequate mix control(1). Preparation of concrete on site should be carried out in accordance with <br />BS 8000-0 : 2014, the Certificate holder’s instructions and this Certificate. <br />(1) NHBC will only accept use of the admixture where included at the concrete batching plant which must also be either QSRMC or BSI Kitemark <br />registered.</p> <p>20.2 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. <br />20.3 Once the fresh concrete is mixed, further materials must not be added. <br />20.4 The workability of concrete can be adjusted using a suitable(1) water reducing or superplasticising admixture <br />complying with BS EN 934-2 : 2009, to ensure that the maximum water/cement ratio given in section 20.2 of this <br />Certificate is not exceeded. Specific admixtures have not been considered and are outside the scope of this Certificate. <br />(1) The Certificate holder’s advice should be sought regarding the suitability and compatibility of water-reducing or superplasticising admixtures. <br />Admixtures should be evaluated before use and site trials should be carried out to establish the appropriate dose required.</p> <p>21 Site mixing <br />21.1 The product is added to the mixer at the correct dose (see section 4.1) prior to batching the concrete constituents. <br />21.2 When an additional superplasticiser is required, it must be added after the addition of the product and in <br />accordance with the supplier’s recommendations.</p> <p>Page 6 of 9</p> <p>21.3 The resulting concrete should be mixed for a minimum of five minutes and in accordance with the Certificate <br />holder’s instructions, to ensure even distribution of the product throughout the concrete. <br />21.4 Where the product is to be added to concrete on site, care must be taken to ensure that adequate mix control is <br />available.</p> <p>22 Placing <br />22.1 Concrete containing the product should be placed in the same way as normal concrete, in accordance with <br />BS 8000-0 : 2014, BS EN 13670 : 2009, the Certificate holder’s Health and Safety guidance and the normal routine <br />precautions for handling concrete. <br />22.2 Concrete containing the product should not be placed at temperatures of 5°C or below. <br />22.3 Concrete containing the product mix should be fully compacted.</p> <p>23 Curing <br />The concrete must be cured strictly in accordance with BS EN 13670 : 2009, and BS EN 1992-1-1 : 2004 and its UK <br />National Annex, and the Certificate holder’s recommendations (where site specific information exists).</p> <p>24 Joints <br />24.1 Joints must be designed with waterstops as recommended in BS 8102 : 2009, to maintain the watertightness of <br />the whole structure. The advice of the Certificate holder should be sought on particular applications. <br />24.2 Penetrations of the concrete, such as pipe entries or formwork ties, must also be securely sealed to maintain <br />watertightness. The Certificate holder can advise on suitable systems.</p> <p>25 Finishes <br />When water-based products are used to coat the hardened concrete, a bonding agent may be required. For specific <br />cases, advice should be sought from the Certificate holder. These are outside the scope of the Certificate.</p> <p>Technical Investigations <br />26 Tests <br />26.1 Tests were carried out and the results assessed to determine the effect of the product on the properties of <br />concrete designed in accordance with BS EN 480-1 : 2014. <br />26.2 Tests were carried out and the results assessed to determine the characteristics of fresh concrete, including:
