摘　　要：设置4个粉煤灰掺加水平(0、50%、75%、100%),通过对24个粉煤灰混凝土试块的抗压强度试验,得到了高掺量粉煤灰混凝土的120 d抗压强度,并应用统计分析软件SPSS 19.0进行回归分析,建立了粉煤灰混凝土的120 d抗压强度与粉煤灰掺加水平之间的回归关系式。结果表明,粉煤灰混凝土抗压强度的预测值与试验值吻合较好。Four kinds of flyash content （0,50%, 75% and 100% ） were considered in this paper.Through the compressive strength test of twenty-four flyash concrete specimens,the 120 d compressive strength of concrete with high content of flyash was obtained.And based on the regression analysis, the regression equation between 120 d compressive strength of flyash concrete and the flyash content was established by using the statistical analysis sottware SPSS 19.0.It could be seen from the results that the prediction of compressive strength of flyash concrete was in good agreement with the experimental values.
