Specification

Application 

1. Sodium lignosulfonate in concrete,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.
