摘要：
Naphthalene sulfate based superplasticizer and poly carboxylate superplasticizer (characterized by different polymerization of graft chain and backbone chain, different reaction temperature and different carboxyl/graft chain ratio) were applied to investigate their influences on fluidity of mineral admixtures (fly ash, granulated ground iron blast furnace slag, silica fume) -Portland cement-water system.
