Water-reducing type polycarboxylate DD-502

详情

DD**02 is a new excogitate environmental superplasticizer.It is a concentrated product, best high water reduction, high slump retention ability, low alkali content for the product, and it having high strength gained rate. It can be widely used in premix of common concrete, gushing concrete, high strength and durability concrete. Especially, it can be used in high strength and durability concrete having excellent capability. It can improve the plastic index of the fresh concretes, thus enhance the pumping performance of the concretes. It exhibits superior cost performance in commercial concretes.

The main chains of the high performance polycarboxylate water reducing agent molecular are absorbed onto the surface of the cement granulates, which can efficiently hinder the hydration, enhance its flowing retention ability, the branch chains surrounded by the cement granulates, play dual roles of steric hindrance and electrostatic repulsion, it is totally different from the traditional water reducing agents, which principal is dispersing cement granulates by electrostatic repulsion, so the high performance polycarboxylate water reducing agents have better dispersion and water reducing effect, which makes the comprehensive performance of the concrete products attain a qualitative leap.
