通过对16组自燃煤矸石粗骨料混凝土试件的试验，研究了自燃煤矸石粗骨料压碎值、水胶比对混凝土抗压强度的影响。利用多元回归建立了自燃煤矸石压碎值、水胶比和混凝土28 d 抗压强度之间的回归方程，并由25组试件检验，普适性良好。自燃煤矸石粗骨料混凝土双变量强度公式的建立，对自燃煤矸石粗骨料混凝土配合比设计及强度推算具有重要的实际意义。

Study on the effect of crushing value of spontaneous combustion gangue coarse aggregate and water - binder ratio to com-pressive strength of concrete by experiment of 16 groups spontaneous combustion gangue coarse aggregate concrete specimen.The re-gression equation about crushing value of spontaneous combustion gangue coarse aggregate,water - binder ratio and 28 d compressive strength of concrete was established.And it is general good using 25groups specimen to test.It is very important practical meanings about mixing design and strength calculation of spontaneous combustion gangue coarse aggregate concrete that bivariate strength formula of spontaneous combustion gangue coarse aggregate concrete was established.
