instructions for use
1. Dosage range: 0.3% ~ 1.0% by weight of cement, the common dosage 0.5% ~ 0.75% by weight of cement. The dosage quantity is calculated by the dry material percentage of cement weight. The dosage quantity of aqueous solution is calculated by converting above content. The final dosage quantity depends, among others,on the reactivity of the cement and the concrete recipe.This must be determined by suitability trials.
