Conplast SP425 is a chloride free workability retention admixture based on selected organic polymers. It is supplied as a brown solution which instantly disperses in water.
Conplast SP425 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The increased workability, cohesion and retardation minimises loss of workability.
- Gives increased working life to fresh concrete
- Increases workability without extra water, reducing placing time and costs
- Improves cohesion, minimising segregation and improving surface finish
- Aids pumping by improving cohesion and reducing workability loss
- Can be used with concrete containing mirco-silica and other cement replacements
