摘要
在分析高性能混凝土对各组成材料的特殊要求的基础上 ,以强度等级 4 2 .5 R的硅酸盐水泥、粒径 5~ 2 0 mm花岗岩碎石、NNO型萘系减水剂及矿物掺合料 (II级粉煤灰和磨细矿渣 )为原材料 ,可配制出具有良好坍落度的 C60、C80高性能混凝土。
After the analysis of the HPC′s special requirement for its composing materials, we can use silicate cement with the strength 42.5R, gravel with grain size 5-20 mm, NNO series naphthyl water reducing agent and mineral admixture (mainly comprised of II grade fly ash and fine lag) to produce C60 and C80 HPC with small slump constant. The strength of the HPC can be achieved by the adjustment of WC ratio and choose of the different admixture.
