SikaPlast®-500

MID-RANGE WATER REDUCING ADMIXTURE

SikaPlast®-500 is a lignin-based mid-range water reducing admixture. SikaPlast®-500 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 SikaPlast®-500.    When used as a mid-range water reducing admixture, water reduction up to 12% can be obtained. At higher dosage rates increased water reduction up to 20% can be achieved making it suitable for some high range water reducing applications. The plasticizing action of SikaPlast®-500 allows for the production of flowable concrete with moderate workability and slump retention that can typically be placed with minimal vibration even at a low water/cementitious ratio.   At lower dosages rates SikaPlast®-500 is an effective normal 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 plasticizing action of SikaPlast®-500 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.    SikaPlast®-500 does not contain any intentionally added chlorides.

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add SikaPlast®-500 directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do NOT mix with dry cement. SikaPlast®-500 may be dispensed on-site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.

  

Compatibility: SikaPlast®-500 can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.
Consumption

Recommended Dosage

The typical dosage rate of SikaPlast®-500 will vary between 3-12 fl oz / 100 lb. (195-780 mL / 100 kg) of cement or cementitious materials. If maximum water reduction is required, dosage rates up to 18 fl oz / 100 lb. (780 ml / 100 kg) of cement or cementitious materials may be used. At low and moderate dosage rates, SikaPlast®-500 performs as a normal and mid-range water reducing admixture. At higher dosage rates, SikaPlast®-500 performs as a high range water reducing admixture. Various factors will affect the dosage rates.

  

Trial mixes with the actual materials should be conducted to determine the required dosage for optimum performance.

  
To the extent specialized materials are used, extreme ambient temperatures are encountered, or for other unusual project conditions, dosage
rates outside the typical range may be required. For dosage rates outside the typical range, please contact your local Sika representative or the Sika Technical Services Department at 1-800-933-7452.
