基于复合矿物掺合料的C30高性能混凝土强度试验研究

Study of the C30 high performance concrete based on the compound mineral material

混凝土是一种多相复合材料,其影响因素很多。针对一种新型的复合矿物掺合料,研究在不同水胶比、不同水泥替代比例以及不同砂率情况下,对这种高性能混凝土的强度影响。同时还给出了在标准养护环境和实际工程养护环境下,基于此种特殊掺合料的高性能混凝土强度差异的对比分析。从工程安全角度的考虑,优选了一组C30配比作为工程应用。

Concrete is a kind of polyphase and compound material, be influenced with many factors. According to a kind of new compound mineral material, the paper researches the HPC＇s strength with water cement ratio, cement＇s substitution rate and sand ratio variating. The paper gives the difference of the HPC＇s strength in standard curing condition and engineering curing condition. Considering engineering safety, the paper selects a C30 mixture ratio to be applied a engineering.
