Products of Yunsong Chemistry Are Mainly Divided into Four Parts.
PCE is a new generation high performance superplasticizer based on polycarboxylate technology. With featured advantages of high water reduction, excellent slump retention ability and low alkali content, it can be widely used in premix of common concrete, gushing concrete and hydro concrete. It's also suitable for engineering projects under various weathers and especially a preferred choice in hot climate area.
