二灰稳定再生集料的劈裂试验研究

采用石灰、粉煤灰及再生混凝土集料为原料，配制成二灰稳定再生集料。通过劈裂试验等，对不同配合比的二灰稳定再生集料的28d间接抗拉强度进行了研究，分析了混合料的组成成分对其间接抗拉强度的影响，并将其与同等条件下的普通二灰稳定集料进行了对比试验。最后根据试验结果建立了它们之间的回归关系，为二灰稳定再生集料的工程应用提供一些有益的参考和建议。

Research on Split Test of Recycled Concrete Aggregate Stabilized by Fly-Ash and Lime

In this paper,the recycled concrete aggregate stabilized by fly-ash and lime(RSFL) is designed and made from lime,fly-ash and recycled concrete aggregate(RCA).On the basis of the split test,the 28 d indirect tensile strength of RSFL is tested,and influences of ratio of lime to fly-ash and content of recycled concrete aggregate on the split test of RSFL are also undertaken,then the results of split test and the ordinarily concrete aggregate stabilized by fly-ash and lime(ASFL) are contrasted on the same condition.Finally,according to the results of split tests,the relations of regression curves are established,and these conclusions would offer reference and suggestion for civil engineering.
