Sikament®-475 is a multi-range water reducing admixture with extended workability utilizing the combination of Sika's ViscoCrete® and ViscoFlow®
polycarboxylate technology. Sikament®-475 meets the requirements of ASTM C494/AASHTO M 194, Type A & F.

Sikament®-475 provides the maximum level of slump retention in the Sikament® product line. Various levels of water reduction can be achieved by adjusting the dosage rate of Sikament®-475.   
When used as a high range water reducing admixture, water reduction up to 25% can be obtained. The superplasticizing action of Sikament®-475 allows for the production of high slump/flow concrete with excellent workability and extended slump retention that can typically be placed with minimal vibration even at a low water/cementitious ratio.    At lower dosage rates Sikament®-475 is an effective normal water reducing or mid-range water reducing admixture. This application is ideal for use with lean, harsh concrete mixes or concrete containing supplementary cementitious materials.    The combined water reducing and superplasticizing action of Sikament®-475 provides the following benefits:   
▪ Reduced water cement ratios produce more durable, dense concrete,
▪ Reduced concrete stickiness results in lower pumping pressures,
▪ Increased slump and workability improves efficiency of labor and reduces labor costs,
▪ Improved finishing characteristics,
▪ Increased strengths allow faster structural use of concrete.   
Sikament®-475 does not contain intentionally added chlorides.
