中文摘要：

以辽宁阜新矿区所产废渣自燃煤矸石为骨料,添加适当粉煤灰,配制混凝土空心砌块.依据均匀设计理论设计实验方案,研究不同配合比情况下煤矸石混凝土空心砌块的表观密度、吸水率、相对含水率、软化系数、碳化系数、抗冻性和抗压强度等性能指标.通过回归分析,得到抗压强度方程.利用BP神经网络预测出煤矸石混凝土砌决抗压强度,预测结果与实验结果吻合较好.实验与计算结果表明,采用煤矸石配制混凝土砌块,强度达到建材使用标准,能降低工程造价,且可以有效治理环境污染,工艺先进,值得大力推广使用.

英文摘要：

The coal gangue concrete hollow blocks were prepared with the self-ignition gangue and fly ash in Fuxin mine. Based on the theory of uniform design, the apparent density, water sorption, relative water content, soften coefficient, carbonized coefficient, frost resistance strength loss and frost resistance quality loss of the coal gangue concrete hollow block in different mixing proportion were studied, and the compressive strength equation was obtained by regression analysis. The compressive strength of coal gangue concrete hollow block was predicted by BP neural network, it showed that the predicted results were in good agreement with the test results. The test and calculation results indicated that using the coal gangue concrete block which strength reached the standard of building materials could reduce the engineering cost, control environmental pollution, in advanced technology, and worthy recommending.
