摘　　要：在正交试验的基础上研究了在不同水胶比、再生骨料掺量、粉煤灰掺量条件下对再生混凝土的各项力学性能指标的影响,对试验结果进行了极差和方差分析,得出水胶比,再生骨料掺量和粉煤灰掺量对各指标的影响规律。在此试验基础上,引用了一些国内外再生混凝土的试验结果,采用回归分析的方法,分别建立了劈裂抗拉强度、抗折强度、弹性模量与立方体抗压强度的关系。Based on the orthogonal tests,the mechanical performance indexes of recycled aggregate were studied under the different water-binder ratios,percentages of recycled aggregate and percentages of fly ash replacements, the rank of significance analysis and the analysis of variances were proposed according to the test results, it was concluded that the influences of water-binder ratio, the percentage of recycled aggregate and the percentage of fly ash to the test results.Based on this test, considering some domestic and foreign recycled concrete test results, using the regression analysis, the conversion relationships between the splitting tensile strength, flexural strength, the elastic modulus and compression strength were established.
