Abstract

In order to solve the problems such as wide fluctuation of concrete fluidity, too fast loss and water secretion caused by the variation of polycarboxylate superplasticizer for concrete preparation. In this paper, a kind of polycarboxylate superplasticizer with multiblock low sensitive(PE-K) was prepared by modified polyether (TPEG), acrylic acid (AA), acrylamide (AM), and 2-acrylamide-2-methyl propanesulfonic acid (AMPS) in the presence of initiator at 50 centigrade. Results showed that the PE-K had lower dosage sensitivity, temperature sensitivity and the water consumption sensitivity performance compared with PE-01.
