This forms a concrete which <br />is sustainable and permanently impermeable to water. <br />• Liquid <br />• Innovative 2 in 1 technology <br />• Crystallization of the capillaries <br />• Water reducing up to 10% <br />• Crack healing possible for penetrating cracks up to <br />0.4 mm and for map/pattern cracks up to 0.5 mm <br />• Improvement of the resistance to freeze/thaw <br />• Reduction in Chloride migration <br />• Minimization of maintenance and repair costs <br />• Time saving <br />• Simple and assured</p> <p>Concrete requirements: <br />Minimum cement content: CEM I <br />270 kg/m³ <br />CEM II <br />290 kg/m³ <br />CEM III /A 380 kg/m³ <br /> Pozzolanic cement with <br />pozzolan content >20%: <br />300 kg/m³ <br />Granulated slag: <br />max.100 kg/m³ <br /> Fly ash: <br />max. 80 kg/m³</p> <p>1/2</p> <p>42/19</p> <p>Advice: <br />• A storage temperature of > 30°C can lead to a brown <br />discoloration of BETOCRETE-CL170-P. This has no <br />influence on the product features. <br />• BETOCRETE-CL170-P has to be thoroughly mixed after <br />a longer storage period (> 2 months). <br />• Carry out preliminary trials in accordance with current <br />standards before using BETOCRETE-CL170-P or other <br />types of additives. <br />• Lignite fly ash is only suitable with restrictions. <br />• The use of CEM III/B&C cements is excluded. <br />• The prescribed crack width restrictions given by <br />the Planner/Engineer/Structural Engineer must be <br />respected in all circumstances. Differing interpretations <br />are to be proven with relevant design verification and <br />design suitability. <br />• Concrete with BETOCRETE-CL170-P must be produced, <br />installed and cured following current valid standards. <br />• In rare circumstances BETOCRETE-CL170-P may <br />influence the initial set of the concrete. As a system <br />compatible product, RUXOLITH-T5 (VZ) is available to <br />control the concrete.</p> <p>Product preparation: <br />Dosage: <br />The required dosage rate is 1.75–2.25% based on CEM <br />weight and is dependent, amongst other criteria, on the <br />concrete formula and the reactivity of the cement. The <br />dosage is to identify with a suitability trial. The following <br />dosage levels have stood the test of time: <br />w/c value < 0.4 <br />1.75% based on CEM <br />> 0.4–0.5 <br />1.85% based on CEM <br />> 0.5–0.55 <br />2.00% based on CEM <br />Do not exceed the maximum dosage level of 2.25 % <br />based on CEM weight. <br />For large cement quantities (≥ 400 kg/m3) a dosage of <br />7 kg/m3 is sufficient. <br />Dosage at concrete plants: <br />BETOCRETE-CL170-P can be added to the mix water or <br />added to the finished concrete mix. <br />Dosage in concrete trucks: <br />Place all the BETOCRETE-CL170-P into the mixing drum <br />and then mix well for 1 minute per m3 of drum contents but <br />for a minimum of 5 minutes and use quickly.</p> <p>Please observe a current valid EU safety data sheet!</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
