Application

Application Information

Dispensing

Sika® Plastocrete® RM/C should be dispensed directly into the mixing water prior to its addition to the aggregates. When accidental overdosing occurs, Sika® Plastocrete® RM/C does not entrain excessive amounts of air. During any overdosing circumstances, where its effect is an extended setting time, the concrete must be kept moist or be covered with PE sheet to prevent premature drying out.
Consumption

Recommended Dosage

0.2% - 0.9% by weight of total cementitious binder. Exact dosage rate properties variation of the constituent materials and the temperature, hence it is advisable to carry out trial mixes. Sika® Plastocrete® RM/C is compatible with all types of Portland cement including S.R.C.
