摘要
Abstract
The work performance and mechanical properties of sulphoaluminate cement by adding polycarboxylate superplasticizer ( PCE) and naphthalene superplasticizer ( FDN) were investigated .The hydrated products of the paste has been analyses with XRD and SEM technologies .The results show that there are saturation points on the effect of the two water reducing agents on the fluidity of the sulphoaluminate cement paste .When compared with FDN superplasticizer , PCE superplasticizer has better water reducing efficiency and dispersibility to sulphoaluminate cement .PCE superplasticizer can hinder the early hydration of sulphoaluminate cement , and reduce the 1 d compressive strength .FDN superplasticizer accelerates the early hydration of sulphoaluminate cement , which shortens the initial setting and final setting time , and improves sulphoaluminate cement 1 d compressive strength .The two kinds of water reducing agents have no effect on the compressive strength and hydration products of sulphoaluminate cement after 3 d.关键词
