Application and Dosage

This product is suitable for mass concrete, liquidity concrete, pumping concrete, concrete construction and commercial concrete and summer have special request for retarded concrete, concrete filling pile, sinking pipe pile concrete, artificial dig-hole pile concrete and underground mass concrete construction, has the good economic efficiency.

Dosage is 0.2%-0.3% based on the weight of cement, recommended dosage is 0.25%.

Features and Benefits

1. Water reducing rate can be up to 9-11% in the appropriate mix content, compared with the reference concrete strength increase 15-20%, 3 days, 7 days strength increased 20-30%, 28 days increase 15-20%, also increase long-term strength.

2. With same water condition of concrete, could increase the fluidity of concrete, improve workability.

3. Keep the same concrete slump and strength, could save cement 8%-10%.

4. Can dely the initial setting time of concrete more than 3 hours, final set time 3 hours, the hydration heat peak delay 5 hours. It is good for summer construction and commercial concrete transportation and mass concrete engineering.

5. This product has entraning air function, the permeability of concrete freeze-thaw performance can be improved.

6. No corrosive for steel and aggregate.
