Mapetard SD 190

Hydration Stabilizer

Mapetard SD 190 is a ready-to-use liquid solution designed to control the hydration process in Portland cement concretes and concrete wash water. This advanced set retarder coats the hydrating cement particles in the concrete and wash water, resulting in the suspension of the hydration chemical reaction.

Mapetard SD 190 maintains the plasticity, slump, and temperature and postpones the set of the concrete for a predictable period of time. Eventually, Mapetard SD 190 is chemically consumed and normal hydration continues. Mapetard SD 190 conforms to ASTM C 494 Type B and CSA A23.1.

Reduces expensive disposal costs associated with returned concrete and concrete wash water
Allows reuse of concrete wash water overnight or over a weekend in many situations
Reduces the amount of concrete wash water needed and truck mixer washouts
Permits long haul applications for extended haul times without slump loss
