Initially it functions chemically and reduces the <br />water absorption in the matrix. In the next step, nano-scale <br />crystals are formed in the capillary system by special <br />active catalysts, which become active on contact with <br />water. This forms a concrete which is sustainable and <br />permanently impermeable to water.</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>• Powder based <br />• Innovative 2 in 1 technology <br />• Crystallization of the capillaries <br />• Reduces capillary absorption <br />• Crack healing possible for penetrating cracks up to <br />0.4 mm and for map/pattern cracks up to 0.5 mm <br />• Reduction in Chloride migration <br />• Improvement of the resistance to freeze/thaw <br />• Minimization of maintenance and repair costs <br />• Time saving</p> <p>1/2</p> <p>18/20</p> <p>Product preparation: <br />Dosage: <br />The required dosage rate is 0.75–1.25% 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. <br />The following dosage levels have stood the test of time: <br />w/c value < 0.4 <br />0.75 % based on CEM <br /> <br />> 0.4–0.5 <br />0.80 % based on CEM <br /> <br />> 0.5–0.55 <br />0.90 % based on CEM <br />Do not exceed the maximum dosage level of 1.25 % <br />based on CEM weight.</p> <p>Advice: <br />• Dependent on composition, concrete modified with <br />BETOCRETE-CP-360-WP can feature crystals on the <br />surface of the concrete. <br />• Carry out preliminary trials in accordance with current <br />standards before using BETOCRETE-CP-360-WP or <br />other 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-CP-360-WP must be <br />produced, installed and cured following current valid <br />standards. <br />• In rare circumstances BETOCRETE-CP-360-WP 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>Dosage at concrete plants: <br />BETOCRETE-CP-360-WP is to be dosed into the <br />aggregate and mixed for a minimum of 30 seconds <br />before adding the water and cement. Subsequently mix for <br />a minimum of 45 seconds until ready for use. <br />Dosage in concrete trucks: <br />BETOCRETE-CP-360-WP is dosed directly into the mixing <br />drum of the concrete truck on the building site. The mixing <br />time should be 1 min/m³ of drum contents but be a <br />minimum of 5 minutes.</p> <p>Please observe a current valid EU safety data sheet!</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
