【摘要】 研究了氨基磺酸盐高效减水剂(PAS)、聚醚多糖、聚丙烯酰胺、聚醚多糖及聚丙烯酰胺与PAS复合对水泥浆的泌水率、流动度及强度等性能的影响。结果显示,聚醚多糖、聚丙烯酰胺、聚醚多糖及聚丙烯酰胺与PAS复合能明显降低水泥浆的泌水率,提高其早期强度;相比较,聚醚多糖与PAS复合后浆体流动性较好,且流动度经时损失较小。更多还原

【Abstract】 The influence of aminosulfonic acid-based superplasticzer,polyacrylamide,polyether polysaccharide,the compound of polyacrylamide or polyether polysaccharide and aminosulfonic acid-based superplasticzer to fresh cement paste weepage,flowability and intension was studied by means of the fluidity,the weepage and so on.The results showed that water-retentive and thickening admixture and the compound of polyacrylamide or polyether polysaccharide and aminosulfonic acid-based superplasticzer could bring down weepage and improve the early strength.Through the compound of polyether polysaccharide and aminosulfonic acid-based superplasticzer,slump loss of cement paste was little.更多还原
