SP 685
Premium superplasticizer for self-compacting concrete

SP 685 is a new generation superplasticizer additive based on polycarboxylate ether technology. This product is designed to maintain slump for a long time to make concrete in hot weather or long transportation conditions and obtain high resistance.

Mechanism of effect:

On the one hand, SP 685 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 preventing the accumulation of cement particles.

Indications:

Pumped concrete, self-compacting concrete, underwater concreting, industrial floor concreting, special concrete with micro-silica, fly ash, slag, etc.

Standard:

ISIRI 2930 – TABLE 12/13

EN 934-2 TABLE 11.1/11.2

ASTM C494 – TYPE G
