product name : Hign-range water-reducing and retarding or superplasticizer and
1. Improve initial slump of concrete 15cm above water reduction of up
to 15 to 25%.
2. High strength, for three days, seven days strength increased by 50-70%, 28 days
more than 30%.
3. Cement consumption can be reduced by 15% to 20%.
4. Greatly improve the workability of concrete
5. Impermeability, freeze-thaw resistance of concrete has been significantly improved.
6. Retarder: It can lengthen the time of concrete hydration hardening,
make the fresh concrete can keep the plastic in a long time, and
can adjust the setting time of fresh concrete.
