As the polycarboxylate-type high performance superplasticizer(PCEs) has the excellent performance on the water reducing
nowadays it has been one of the hottest researches on the concrete admixtures. In the paper
four different molecular structures of PCEs were detailed specified basing on the development history. Meanwhile
there is a contrast about the synthesis of four PCEs and the pros and cons of their performance. According to the problems focused on its poor abilities
such as slump
shrinkage rage
early strength
air entraining and sensibility
which have been studied both at home and abroad. And varieties of feasible solutions have been provided. At last
other aspects of PCEs
such as environmental protection
material price and market demand
have also been briefly described and prospected in the paper.
