Usage and Notes

1. Under the total weight of cement, liquid dosage is 2-4.5%, and powder dosage is 4-8%. The optimum dosage should be determined by test before use. The dosage should be adjusted according to the temperature during construction. For example, appropriately increase the dosage when temperature is low, reduce the dosage when temperature is high. 

2. Strictly control the water-cement ratio, the appropriate eructation should has no flow, no dry spots, and uniform color. 

3. The mixture stand-by time should be controlled when the concrete is sprayed. 

4. Pay attention to wet maintenance, to prevent dry crack after molding. 

5. Refers to relevant provisions of construction of the national standard “concrete admixtures application technical specifications”.
