Premium softener and quick setting of concrete

SP 790 RA is a new generation plasticizing and quick-setting concrete additive based on polycarboxylate ether technology. This product is designed by keeping the slump during the construction and implementation of concrete along with the property of early setting in the cold season and obtaining high resistance.

Mechanism of effect:

On the one hand, SP 790 RA prevents the accumulation of cement particles by creating a repulsion between the cement particles and forming charges of the same name, and on the other hand, by creating a crust on the surface of the cement particles and spatial obstruction, and it is limited by the maximum possible efficiency.

Applications: precast concrete, prestressed concrete, artificial stone, decorative concrete, etc.
