Sika® ViscoCrete TEMPO-12

Superplasticizer / High water reducer with prolonged maintenance of workability Sika® ViscoCrete® TEMPO-12 is a new generation, non-chlorinated superplasticizer based on acrylic copolymers, specially formulated to ensure prolonged workability of concrete while guaranteeing high mechanical resistance. Description Sika® ViscoCrete® TEMPO-12 acts by adsorption of polymers on the surface of cement grains, creating an electrostatic and steric repulsion which allows optimal dispersion of particles. This technology ensures a significant reduction in mixing water while maintaining the fluidity of the concrete over a prolonged period, even in hot climatic conditions. Areas of application Ready-mixed concrete (BPE) Concrete transported over long distances Concretes poured in hot weather Concretes requiring extended processing time Pumped concrete and fluid concrete Advantages Excellent water reduction Extended maintenance of workability Improvement of short and long term mechanical resistance Reduction of the risk of segregation and bleeding Improved compactness and durability of concrete Compatible with the majority of cements Use The dosage depends on the type of cement, the concrete formulation and the desired performance. Preliminary tests are recommended to determine the optimal dosage

Applications
