Sika ViscoCrete-20 HE KE is a liquid admixture for concrete and mortar used as high range water reducer or superplasticiser. Sika ViscoCrete-20 HE KE is designed to work on a combination of electrostatic adsorption and steric repulsion effects allowing solid particles to be effectively dispersed. Therefore, a high level of fluidity and plasticising can be reached with a high water reduction thus providing many advantages. Suitable for use in tropical and hot climatic conditions
