摘要
将建筑垃圾、水泥及粉煤灰按一定配合比组成的建筑垃圾再生骨料替代天然骨料,可大大节约工程成本,对其无侧限抗压强度试验结果进行研究,在再生骨料含量、粉煤灰掺量、水泥掺量三个因素作用下,利用正交试验,分析了三个因素对无侧限抗压强度的影响程度。通过试验研究,选取最佳配合比,结合工程实例进行了地基处理,并通过静载试验对处理后的地基承载力进行检测,证明了其适用性。
The recycled aggregate which mixed proportion of construction waste,cement and fly ash can instead of natural aggregate,which can greatly save engineering cost. In order to the study on unconfined compression strength test of the mixture,considering the amount of aggregate,cement and fly ash,the influencing degree of the three factors are analyzed using the orthogonal experimental. Through the experimental study, selecting the optimal mixing proportion, the ground improvement combining a engineering case is carried out. The bearing capacity of the improved ground is inspected by static loading test and it is proved applicable.
