摘　　要：为了更好地利用和推广自燃煤矸石骨料混凝土,研究其配合比设计和温度公式,以水泥强度等级和自燃煤矸石粗骨料的压碎值为影响因素,通过试验研究二者与自燃煤矸石粗骨料混凝土强度之间的关系。结果表明,水泥强度等级和自燃煤矸石压碎值与混凝土强度之间存在良好的线性关系。建立了自燃煤矸石粗骨料混凝土强度的Bolomey公式,并分析了自燃煤矸石粗骨料混凝土Bolomey公式中回归系数值的修正方法。The mix design and temperature formula of spontaneous combustion gangue aggregate concrete are researched for utilizing and popularizing this kind of concrete preferably. Using the cement strength grade and crushing value of spontaneous combustion gangue coarse aggregate as the influencing factors, the relationship between the two factors and the strength of spontaneous combustion gangue coarse aggregate concrete is studied through experiments. The result shows that （ 1 ） there is a good linear relationship of concrete strength grade with cement strength grade and crushing value of spontaneous combustion coal gangue. The Bolomey formula for the strength of spontaneous combustion gangue coarse aggregate concrete is established, and the revision method to determine regression coefficient and values in the Bolomey formula of spontaneous combustion gangue coarse aggregate concrete is also analyzed.
