Mapeplast R18 SP is a liquid set-retarding admixture for concrete with low slump loss.
Mapeplast R18 SP is a water solution of active polymers that retard cement hydration and limit slump loss in concrete during hot weather and when transporting over long distances. Retention of workability and delay in setting increase the dosage of the admixture, which can vary from 0.2% to 0.5% by weight of cement.
