摘　　要：针对生态混凝土设计中高孔隙率和高强度之间相互矛盾、低碱度难以兼顾的难题,考虑目标孔隙率、水灰比、有机质掺量、灰骨比等四个影响因素,采用正交试验法对生态混凝土的材料配合比进行了优化设计。通过对试验结果进行分析,探讨了不同因素对生态混凝土强度和pH值的影响程度,并得到一组四种因素组合情况下的生态混凝土最优配合比。Aiming at the difficulties of the design of eco-concrete,such as the contradiction between high porosity and high strength,and the difficulty of low alkalinity,the material mixing ratio of eco-concrete was optimized by orthogonal test method,taking into account the four influencing factors such as the target porosity,the water-cement ratio,the admixture of organic matter,and the ash-cement ratio.By analyzing the test results,the influence degree of different factors on the strength and pH value of eco-concrete was explored,and a set of optimal mixing ratios of eco-concrete under the combination of the four factors was obtained.
