Hardening Accelerating Admixture

Product Description

Hardening accelerating admixture
Product feature
1. Appearance: Pale powder. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
2. The combined early-strength powdery agent can improve early strength and save cement.
3. At 0~20 temperature 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%.
4. 12% of water can be reduced when it is applied to normal superplastic concrete at 2%.
5. After application, all physical properties of concrete can be improved to a certain extent.
6.10% of cement will be reserved when it is applied as a condition of blending in which collapsibility and strength are fixed aforehand.

Application
1. Widely used in pre-cast & deposit concrete. Armored concrete, pre-stressed reinforced concrete and fly-ash-cement concrete.
2. Compatible with portland cemen, normal portland cement, porland slag cement, fly-ash cement and portland pozzolanic cement etc.
