Preparation and Properties of Low Air-entraining and Shrinkage-reducing Polycarboxylate Superplasticizer
摘要
Abstract
The crack of concrete caused by shrinkage is a serious problem. A low air-entraining and shrinkage-reducing polycarboxylate superplasticizer was prepared by different type and molecular macro-monomer BPEGMA, MAA, shrinkage-reducing monomer DPGMAL and de-foaming monomer PPGA400. The influences of the amount of all the materials were discussed. The optimal molar ratio of BPEGMA1000, MAA, DPGMAL and PPGA400 was 1∶3. 2∶0. 6∶0. 3. Compared with the like product in the market, the copolymer had the better water-reducing, shrinkage-reducing and lower air-entraining property.关键词
