Instruction for use :

 1. Polycarboxylate based water reducer   dosage normally ranges from 0.15% ~ 0.25% of the total weight of cementitious materials. The final dosage quantity depends, among others, on the reactivity of the cement and the concrete recipe. This must be determined by suitability trials.

2. Polycarboxylate based water reducer    can be added to the sand, stone, cement and other admixtures with the mixing water in the same time, and stir for a time. The product can also be used by after mixing method.
