Sika ViscoCrete 20 HE
DESCRIPTION
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. Suitable for use in tropical and hot climatic conditions.
USES
Production of concrete mixes which require high early strength development, powerful water reduction and improved flowability.
▪ Precast concrete
▪ Fast-track concrete
▪ In situ concrete requiring fast stripping time
▪ Self Compacting Concrete (SCC)
