Usage and precautions
1. The water reduction rate is between 26% -50%, the water content is less than 3%, and the chloride ion is less than 0.03%, PH value (20 ℃) 6-8, surface tension 71.4-72MN/M;
2. The stacking density is 400-700KG/m ³, with a milky white powder appearance and a total alkali content of<5%. It is recommended to add 0.16-0.3% of the total amount of cementitious material;
3. Powder is prone to moisture absorption and should be stored in its original sealed condition. The temperature should not exceed 40 ℃ and should not be stacked too high. The shelf life is generally 12 months;
