石屑对粉煤灰砖抗压强度影响的研究

Influence of Stone Chips on Compressive Strength of Fly Ash Brick

应用正交试验,研究了石屑的配比对粉煤灰砖抗压强度的影响程度;应用逐步去除石粉的方法,分析了石屑中石粉的质量分数及细度对粉煤灰砖抗压强度的影响程度,探讨了石屑在粉煤灰砖中掺入量的最佳配比的改进方法。

By orthogonal test,the author studied the influence of stone chips on compressive strength of fly ash bricks.By progressively reducing stone dust,the author analyzed the influence of degree of mass fraction of stone chips and fineness on compressive strength of fly ash bricks.Also the author discussed the perfect matching of stone chips in fly ash bricks.
