石灰-粉煤灰稳定煤矸石混合料抗压强度试验研究

Experimental Research on the Compressive Strength of Coal Gangue Mixtures Steadied by Lime-Fly Ash

通过室内试验,研究了邢台某矿区煤矸石混合料的物理、化学性能。采用均匀设计方法,设计了6组煤矸石混合料的试验配比方案,并分别对不同配合比的混合料进行饱水无侧限抗压强度试验,利用回归分析模型对试验结果进行分析,研究讨论掺合料(生石灰、粉煤灰)掺量对煤矸石混合料强度的影响。

The physical and chemical performances of coal gangue in the Xingtai area are studied based on the indoor experiments. By uniform design method, 6 groups mix proportion schemes of coal gangue mixtures are designed. And the experiment of compressive strength with full water and no lateral restraint is carried out for the mixtures with different mix proportion. Using the regression analysis model, the experimental results is analyzed. The influence of the contents of admixtures（quick lime, fly ash） on the strength of the coal gangue mixture is discussed.
