摘要
基于图形分析,对水灰比为0.29、掺与不掺抗泥型聚羧酸减水剂(PCE)的硬化水泥浆体7 d和28 d宏观孔隙率进行了半定量表征及分形计算,发现掺用抗泥型PCE能降低水泥石的宏观孔隙率及宏观孔的分形维数。
Macro porosity of hardened cement paste with and without clay compatible polycarboxylate ether （PCE） superplasticizer, and with water to cement ratio of 0.29, cured for 7 d and 28 d are semi quantitative characterized and fi＇actal calculated based on graphic analysis. Calculation results indicate that the addition of clay compatible PCE may significantly reduce tile macro porosity in hardened cement paste, and may enhance fraetal dimension of macro pore.
