PC-3(Polycarboxylate Superplasticizer), containing polycarboxylic ether copolymer, is the new generation of the high performance water reducer. The product has its excellent performance for the slump retention and water reducing. PC-3，free of chloride complies with The China’s Standard for Concrete Admixture of GB8076-2008 and U.S. Standard of ASTM C94 Type F, as well as the EU Standard of EN934-2 T3.1/3.2. PC-3 is compatible with all types of Portland cement which are complying with the international standards. The difference between PC-3 and the traditional high range water reducer is that PC-3 is based on its unique side chain polycarboxylic ether copolymer. Therefore, it enhances the dispersion of cement greatly. Furthermore, the copolymer has the effect of slow-release with prolonged time of slump retention and no delayed setting.
