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28 d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。 Using lime, fly ash and recycled aggregate concrete as raw materials, formulated as a lignite stable renewable aggregate. Through the splitting test and so on, the indirect tensile strength of lime-flyash stabilized recycled aggregates with different proportions was studied for 28 days. The influence of the components of the mixture on the indirect tensile strength was analyzed and compared with the same conditions Under the normal lime-ash stable aggregate conducted a comparative test. Finally, the regression relationship between them is established according to the test results, which provides some useful references and suggestions for the engineering application of lime-flyash stabilized recycled aggregates.
