CL-ES-50 Polycarboxylate Superplasticizer 50%(Early Strength&Water Reducing Type)
CL-ES-50 is an Eco-friendly new generation high performance polycarboxylate superplasticizer developed by our company with raw material (with average molecular weight 5000).
It is based on the action between polycarboxylate superplasticizer molecule and cement, designing special structure molecule of polycarboxylate to promote combination of granules of cements and hydrone to consummate hydrating and enhance the initial strength.

Application
CL-ES-50 can be widely used in all kinds of precast concrete,prefabricated products,early strength and high early-strength concrete.
Usage
1. Recommended dosage ( by binding materials’ weight) is 0.35%-0.55% (on the base of 50% solid content). The optimum dosage is according to the real project conditions and actual materials.
2. Compatibility test should be done in advance when used with other additives.
3. Precise measurement avoids repeat dosage and errors.
