Sika® Plastocrete®-161

WATER REDUCING ADMIXTURE

Sika® Plastocrete®-161 is a lignin-based, normal range water reducing admixture. Sika® Plastocrete®-161 meets the requirements of ASTM C494/AASHTO M 194, Type A, B, & D.

Various levels of water reduction can be achieved by adjusting the dosage rate of Sika® Plastocrete®-161.      At lower dosage rates Sika® Plastocrete®-161 provides mild water reduction and workability. At higher dosage rates Sika® Plastocrete®-161 provides moderate water reduction up to 10% and workability retention with extended set times.
     Sika® Plastocrete®-161 allows for the production of concrete that can typically be placed with reduced vibration. Sika® Plastocrete®-161 is effective for use with lean, harsh concrete mixes or concrete containing supplementary cementitious materials.    Sika® Plastocrete®-161 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 strengths allow faster structural use of concrete.    Sika® Plastocrete®-161 does not contain intentionally added chlorides.
