Sikament®-1 R4 is a highly effective superplasticizer with a set retarding effect for producing concrete in hot climate and also a substantial water reducing agent for promoting ultimate strength.
Sikament®-1 R4 complies with ASTM C494 type D & G.
As a superplasticizer with set retarding effect:
- Highly effective without increased w/c ratio
- Lasting control of slump loss
- Controlled setting time
- Avoidance of cold joints
- No adverse effect on ultimate strength
- Strength significantly increased
- Allow substantial cement reduction compared to plain concrete
- Especially suitable for hot climate
- No excessive air entrainment
- No adverse shrinkage effect
- Improved surface finish
