Nano-crystals are formed in the capillaries <br />by special catalysts, which become active on contact <br />with water forming a sustainable and permanently water <br />impermeable concrete. In addition, reinforcing steel is <br />protected against corrosion.</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 />• Crack healing possible for penetrating cracks up to <br />0.4 mm and for map/pattern cracks up to 0.5 mm. <br />• Corrosion inhibitor. <br />• Improvement of the resistance to freeze/thaw. <br />• Reduction in Chloride migration. <br />• Protects reinforcement from corrosion. <br />• Minimization of maintenance and repair costs. <br />• Time saving.</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. The following <br />dosage levels have stood the test of time: <br />w/c value <br /> 0.4–0.5 <br />0.80 % based on CEM <br /> <br />> 0.5–0.55 0.95 % based on CEM <br />Do not exceed the maximum dosage level of 1.25 % <br />based on CEM weight.</p> <p>Areas of application: <br />BETOCRETE-CP-350-CI can be applied to all concrete <br />where water penetration should be permanently <br />prevented. <br />These are for example: Cooling towers at power stations, <br />tanks and containers, retaining basins, swimming pools, <br />parking garages, parking lot levels, foundations, sandwich <br />units, waterproof concrete, sewer channels/manhole <br />access points, tunnels, concrete pipes and everywhere, <br />where watertightness is needed.</p> <p>Dosage at concrete plants: <br />BETOCRETE-CP-350-CI is to be dosed into the aggregate <br />and mixed for a minimum of 30 seconds before adding <br />the water and cement. Subsequently mix for a minimum of <br />45 seconds until ready for use.</p> <p>1/2</p> <p>03/18</p> <p>Dosage in concrete trucks: <br />The addition of BETOCRETE-CP-350-CI on site <br />(concrete truck) is not carried out as a powder but as <br />a very aqueous suspension. The required amount of <br />BETOCRETE-CP-350-CI is premixed with water at a ratio <br />of 1:1 (5 kg BETOCRETE-CP-350-CI and 5 kg water) <br />using a suitable vessel and stirrer and then completely <br />emptied into the mixing drum of the truck. The secondary <br />mix time should be 1 min/m³ of drum contents but at least <br />5 minutes. Ensure that additional water from the prepared <br />suspension does not increase the required w/c value <br />specified. Otherwise the water in the concrete recipe must <br />be considered during production and prior to the addition <br />of the suspension. <br />Advice: <br />• Dependent on composition, concrete modified with <br />BETOCRETE-CP-350-CI 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-350-CI 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-CP-350-CI must be <br />produced, installed and cured following current valid <br />standards. <br />• In rare circumstances BETOCRETE-CP-350-CI 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. <br />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.
