摘要
对掺几种高效减水剂和引气剂的混凝土性能进行了试验 ,试验结果表明 ,掺缓凝高效减水剂、引气剂和Ⅰ级粉煤灰 ,可显著降低混凝土的单位用水量 ,改善混凝土的和易性 ,提高混凝土的强度和耐久性。
? In this paper,ths properties of conorete with superplastioizer and air entralning admixture is studied The results shows that the concrete with superplesticizer,air antraining admixture and class fly ash can observably reduce water content,ameliorate workability,and increase strength and durability of concrete. 〔
