摘 要:以废弃混凝土为原料配制再生混凝土。通过对再生混凝土进行拉拔试验,研究再生粗骨料取代率和水灰比对再生混凝土的握裹力及抗压强度的影响,并对试验现象进行了分析和总结。结果表明,再生混凝土的粘结强度大于普通混凝土的粘结强度,并对水灰比给出了合理的取值范围,为再生混凝土的进一步推广应用提供了试验依据。
Abstract: Recycled concrete is prepared by the waste concrete as aggregate materials. Through the pull-out test related to recycled concrete, the effects of recycled coarse aggregate replacement rate and cement-water ratio on the bond stress and compressive strength of recycled concrete are studied. From the experiment and the analysis, the cohesional strength of recycled concrete is stronger than that of common concrete. Rational range of cement-water ratio is given and it can provide theoretical basis for further application of recycled concrete.
