HIGH RANGE WATER REDUCING/SUPERPLASTICISING ADMIXTURE FOR METAKAOLIN CONCRETE Sika® ViscoCrete®-650 MK is a liquid admixture for concrete based on unique polycarboxylate polymers technologies. Sika® ViscoCrete®-650 MK is designed as a high range water reducer or superplasticiser. It is particularly suited for use in Metakaolin concretes that require low water/cement ratios and / or high water reductions whilst maintaining excellent workability retention properties. Sika® ViscoCrete®-650 MK meets the requirements of BS EN 934-2 table. |
Usage Sika® ViscoCrete®-650 MK is a unique product that is suitable for the production of ready mixed concrete or pre cast concrete ▪ Ideally suited for use in SCC and flowing concretes ▪ Suitability for use across broad range of consistence classes from S4 – SF3 ▪ High performance concrete ▪ High rise/pumped concrete ▪ Slip form concrete - Improved effectiveness in higher ambient temperatures
Advantages High range water reductions resulting in higher strengths and densities ▪ Extended consistence retention ▪ Improved cohesion properties ▪ Improved early and ultimate strengths ▪ Excellent placement characteristics ▪ Improved rheology ▪ Improved durability ▪ Reduced segregation and bleeding ▪ Reduced drying shrinkage ▪ Reduced mix costs |
Technical Information Specific Advice Alkali Content: Awaiting further testing Freezing Point: Awaiting further testing Air Entrainment: Negligible, minimal increase Effect of Setting: Minimal effect Effect of Overdosing: Increased workability and segregation |
