Sika® ViscoCrete®-4100


Sika® ViscoCrete®-4100 is a high range water reducing admixture utilizing Sika's ViscoCrete® polycarboxylate technology. Sika® ViscoCrete®-4100 meets the requirements of ASTM C494/AASHTO M 194, Type A & F.

Various levels of water reduction can be achieved by adjusting the dosage rate of Sika® ViscoCrete®-4100.    When used as a high range water reducing admixture, water reduction up to 40% can be obtained. The superplasticizing action of Sika® ViscoCrete®-4100 allows for the production of high/slump flow concrete with excellent workability that can typically be placed with minimal vibration even at an extremely low water/cementitious ratio.
   At lower dosages rates Sika® ViscoCrete®-4100 is an effective normal water reducing or mid-range water reducing admixture.  This application is ideal for use in conventional concrete containing supplementary cementitious materials.   The combined water reducing and superplasticizing action of Sika® ViscoCrete®-4100 provides the following benefits:
▪ Reduced water cement ratios produce more durable, dense concrete, ▪ Increased slump and workability improves efficiency of labor and reduces labor costs, ▪ Improved finishing characteristics,
▪ Increased early and ultimate strengths allow faster structural use of concrete, ▪ Increased early strengths allow faster demolding and more efficient use of forms for precast producers.
   Sika® ViscoCrete®-4100 does not contain intentionally added chlorides.
