C80自密实高性能混凝土的试验研究与应用

Experimental investigation and application of C80 self-compacting concrete

本文采用聚羧酸系高效减水剂,通过对硅灰、粉煤灰及矿渣粉不同组合的试验研究,在不掺加硅灰的情况下,配制出成本低廉、工作性能良好的C80级自密实混凝土,并在工程中成功应用。

Through the experiment of mixing silica fume,fly ash and scoria ash with high efficiency water reducing agent of polycarboxylate,it prepared an inexpensive and good workability C80 self-compacting concrete,which succeeded in construction.
