Conplast RP264M2 is a dark brown liquid based on modified selected lignosulphonates.
When added to concrete, Conplast RP264M3 is absorbed on to the cement, and acts as a dispersing agent by breaking down the agglomerates of cement particles. This enables the mix water to perform more efficiently. Conplast RP264M2 delays the initial hydration of the cement resulting in retardation of setting time.
Once the concrete has undergone initial set, the hardening process continues normally.
