VISCOCRETE 3355 200 LTRS DRUM – WATER RETARDER | NASIR & SONS | SIKA PAKISTAN

Concrete Admixture For High Flow / Self-Compacting Concrete USES Sika® ViscoCrete®-3355 facilities extreme water reduction, excellent flowability with optimal cohesion and strong self-compacting behavior. ® 3355 is used for the following types of concrete: ▪ High flow concrete ▪ Self-compacting, concrete (S.C.C.) ▪ Concrete with high water reduction (upto 30%) ▪ High strength concrete The combination of high-water reduction, excellent flowability and high early strength provides clear benefits in the above-mentioned applications.   CHARACTERISTICS / ADVANTAGES Sika® ViscoCrete®-3355 acts by surface absorption on the cement particles producing a sterical separation effect on the cement particles. Concrete produced with Sika® ViscoCrete®-3355 exhibits the following properties: Excellent flowability (resulting in highly reduced placing and compacting efforts) ▪ ▪ Strong self-compacting behaviour Extremely high water reduction; > 25% (resulting in high density and strengths) ▪ ▪ Increased high early strength development ▪ Improved shrinkage and creep behaviour ▪ Reduced rate of carbonation of the concrete Sika® ViscoCrete®-3355 does not contain chlorides or other steel corrosion promoting ingredients. Therefore, it maybe used without restriction for reinforced and pre-stressed concrete construction. Sika® ViscoCrete®-3355 gives the concrete extended workability and depending on the mix design and the quality of material used, self-compacting properties can be maintained for more than 1 hour at 30°C. APPROVALS / STANDARDS Sika® ViscoCrete®-3355 follows the requirements of ASTM C494; Type G.
