Sika® ViscoCrete® Strike

Accelerating High Range Water Reducing/Superplasticising Concrete Admixture

Sika® ViscoCrete® Strike is based on unique polycarboxylate polymers technologies. Sika® ViscoCrete® Strike is a liquid admixture for concrete which is used as an accelerating high range water reducer or superplasticiser. The product provides fast adsorption resulting in highly efficient dispersion and potential reduction in mixing time. It meets the requirements of BS EN 934-2
