复掺混合材对水泥及混凝土性能影响的试验研究

Effect of composite admixture on performance of cement and concrete

研究了石灰石、矿渣、烧页岩及粉煤灰四种混合材复配对水泥及混凝土性能的影响。试验结果表明,矿渣和石灰石有益于改善水泥的标准稠度用水量、外加剂相容性、混凝土的工作性能及强度,而烧页岩和粉煤灰有益于水泥的强度,几种混合材的合理搭配可以改善水泥和混凝土的性能。

The effect of composite admixture,such as limestone,blast furnace slag,calcined shale and fly ash,on the performance of cement and concrete were studied.The results showed that mixed limestone and blast furnace slag with clinker could be benefit to improve water requirement of normal consistency of cement,compatibility of cement and additive,working performance and strength of concrete.The calcined shale and fly ash could be benefit to improve strength of cement.The reasonable collocation of several admixtures could improve the performance of cement and concrete.
