Sika® ViscoCrete®-20 HE is a liquid admixture for concrete and mortar which is used as high range water reducer or superplasticiser. Sika® ViscoCrete®-20 HE 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 which provides many advantages.
Production of concrete mixes which require high earlystrength development, powerful water reduction and
