Sika® ViscoCrete®-200 EPC
High Range Water Reducing / Superplasticizing Admixture for Precast concrete
Sika® ViscoCrete®-200 EPC is a polycarboxylate based superplasticizer particularly developed for use in the precast industry to give high workability at low water: binder ratios with normal setting times.
Suitable for use in hot and tropical climatic conditions.
Sika® ViscoCrete®-200 EPC acts as a powerful superplasticizer by both surface adsorption and steric hindrance effects separating the binder particles resulting in:
- Higher dispersion
- The possibility to work with very low water/binder ratios and avoiding the high stickiness common to such kind of mixes
- Easier to control during casting due to sufficient retention period and high early strength development
- Extremely high water reduction (resulting in high density and strengths) even in double or triple blend mixes (e.g. cement, GGBS, and silica fume)
- Low water permeability and chloride migration
- Increased high early strength and strength development even with the use of low cement content mixes
- Improved shrinkage and creep behavior
- Excellent flow ability resulting in minimal placing and compacting efforts leading to much denser concrete
- Does not contain chlorides or other steel corrosion promoting ingredients
