Abstract

Through the adjustment of polyether monomer, polyether molecular weight and early strength functional monomer, the best process formula was determined, and its molecular weight was tested by gel permeation chromatography, as well as the product performance. The experimental results showed that the early strength polycarboxylate water reducer (ES-PCE)was prepared by solution polymerization using a vinyl polyoxyethylene ether with a molecular weight of 5000 and a 2-acrylamido-methylpropane sulfonic acid in the ammonium persulfate, hydrogen peroxide, and sodium bisulfite initiator system. Compared with similar products PC-1 and PC-2, the compressive strength of ES-PCE at 1d, 7d, and 28d was comparable to that of similar products PC-1, Compared to similar domestic products PC-2, it is about 2 ~ 3 MPa higher, indicating that ES-PCE can completely replace similar foreign products, to improve template turnover rate. Thereby it promotes the rapid development of prefabricated buildings.
