Measure the required quantity manually or by automated dispenser. Add SikaPlast®-300 GP directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do not mix with dry cement. SikaPlast®-300 GP 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.

Compatability:

SikaPlast®-300 GP can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.

The typical dosage range for SikaPlast®-300 GP is 2-12 fluid ounces per 100 lbs. (130-780 ml per 100 kg) of cementitious material. For maximum water reduction, dosage rates up to 20 fluid ounces per 100 lbs. (1300 ml per 100 kg) of cementitious material may be used. At higher dosages, delayed setting time will likely occur.

Dosage rates vary depending upon the amount of plasticity and/or water reduction desired. Slump, ambient temperature, water-cementitious ratio, mixing time and various concrete materials, such as type of cement and supplementary cementitious materials, will affect dosage rates. It is recommended to conduct trial mixes with the actual materials to determine the required dosage for optimum performance.

To the extent specialized materials (such as microsilica) are specified, extreme ambient project conditions are encountered, or other unusual project conditions require special consideration outside the recommended dosage, please contact your local regional Sika office or Sika technical service department at 1-800-933-7452 prior to using the Sika admixture.
