Properties and purposes:
Hardening accelerating admixture belongs to hardening accelerating and water reducing admixture. Apply for reinforced concrete projects of big moulding board, slip form structure, etc. It can reach stripping formwork strength within 10 hours under normal temperature, reach 50% of designed strength within 1 day, 3 days concrete strength with admixture can reach 28 days concrete strength that without admixture. It can also be used in concrete or cement mortar under minus 8℃.
