Hardening Accelerating Admixture
Widwly used in pre-cast & deposit concrete. Armored concrete, pre-stressed reinforce concrete and fly-ash-cement concrete.
Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolana cement etc.
Suitable for self-cured concrete and its formulations. It has remarkable effects of water reduction and enhancement, especially at the early stage. The modulus and utilization can be improved.
Appearance pale powder. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
The combined early-strength powdery agent can improved early strength and save cement
At 020 compression strength can be increased by 80% on the 1st day, 60% on the 3rd day, 30% on the 7th day and 15% on the 28th day when the agent is added at 2%.
12% of water can be reduced when it is applied to normal superplastic concrete at 2%.
After application, all physical properties of concrete can be improved to a certain extend.
10% of cement will be reserved when it is applied as a condition of blending in which collapsibility and strength are fixed a forehand
RECOMMENDED BLEND DOSAGE:
Power 1:5 water dilute = 300 to 500 gms per bag cement
The blend dosage normally ranges from 2% the standard blend dosage is establish 2%
the powdery agent can be agitated to gether with cement .accurate measurement is essential
A-30 –second agitation is required to archive good homogeneity
