泥含量对掺聚羧酸减水剂混凝土的影响及措施

Negative effects of high clay content on cement mixed with polycarboxylic water-reducer and measures to reduce these effects

通过现场对比试验,分析了泥含量对掺聚羧酸减水剂混凝土的影响,并通过大量试验找了一种能够减少泥含量影响的保坍剂,与之复配,使混凝土的性能比原来有所提高。

Through on-site contrastive experiment,this paper conducts an analysis on the negative effects of high clay content on cement mixed with polycarboxylic water-reducer and discovers by numerous experiments a kind of high effect retarder to restrain slump,which can reduce the influence of clay content.Furthermore,this retarder is to formulate with the cement mixed with polycarboxylic water-reducer.The result indicates that the performance of cement is significantly improved.
