BETOCRETE-CL210-WP is a liquid admixture for designing a water tight concrete with innovative 2 in 1 technology. Initially it functions chemically and reduces the water absorption in the matrix. In the next step, nano-scale crystals are formed in the capillary system by special active catalysts, which become active on contact with water. This forms a concrete which is sustainable and permanently impermeable to water. • Liquid • Innovative 2 in 1 technology • Crystallization of the capillaries • Reduces capillary absorption • Crack healing possible for penetrating cracks up to 0.4 mm and for map/pattern cracks up to 0.5 mm • Improvement of the resistance to freeze/thaw • Reduction in Chloride migration • Minimization of maintenance and repair costs • Time saving • Simple and assured

Advice: • A storage temperature of >30°C can lead to parts of BETOCRETE-CL210-WP settling. After thorough mixing, this has no influence on the product features. • BETOCRETE-CL210-WP has to be thoroughly mixed after a longer storage period (>1 month). • Carry out preliminary trials in accordance with current standards before using BETOCRETE-CL210-WP or other types of additives. • Lignite fly ash is only suitable with restrictions. • The use of CEM III/B&C cements is excluded. • The prescribed crack width restrictions given by the Planner/Engineer/Structural Engineer must be respected in all circumstances. Differing interpretations are to be proven with relevant design verification and design suitability. • Concrete with BETOCRETE-CL210-WP must be produced, installed and cured following current valid standards. • BETOCRETE-CL210-WP does not contain materials which cause corrosion. • In rare circumstances BETOCRETE-CL210-WP may influence the initial set of the concrete. As a system compatible product, RUXOLITH-T5 (VZ) is available to control the concrete.
Product preparation: Dosage: The required dosage rate is 1.75–2.25% based on CEM weight and is dependent, amongst other criteria, on the concrete formula and the reactivity of the cement. The dosage is to identify with a suitability trial. The following dosage levels have stood the test of time: w/c value < 0.4 1.75 % based on CEM > 0.4–0.5 1.85 % based on CEM > 0.5–0.55 2.00 % based on CEM Do not exceed the maximum dosage level of 2.25 % based on CEM weight. Dosage at concrete plants: BETOCRETE-CL210-WP can be added to the mix water or added to the finished concrete mix. Dosage in concrete trucks: Place all the BETOCRETE-CL210-WP into the mixing drum and then mix well for 1 minute per m3 of drum contents but for a minimum of 5 minutes and use quickly.
