低品质粉煤灰混凝土基本力学性能试验研究

Experimental study on basic mechanical properties of concrete incorporation of Low–quality fly ash

有效提高低品质粉煤灰的利用率具有重大的环保意义和经济效益。本文采用试验方法,对低品质粉煤灰混凝土的基本力学性能包括轴心抗压强度、劈裂抗拉强度、静力受压弹性模量等进行了研究,探讨了适用于中等及轻交通等级公路路面结构层中低品质粉煤灰混凝土的最大掺量。研究结果可为低品质粉煤灰在公路路面结构层中的推广应用提供理论数据。

Effectively improve the utilization of Low - qual.ity fly ash has great significance to environmental protection and economic benefits. The basic me-chanical properties such as axial compressive strength, splitting tensile strength, modulus of elasticity, etc. have been studied by experiment method in this paper. And the maximum volume of Low - quality fly ash used in medium and light traffic level was discussed. The conclusions can provide theoretical data for the application of low quality fly ash in highway pavement structure layer.
