摘要
用再生混凝土骨料替代原生粗骨料,用30%粉煤灰等量替代水泥制作10根试验梁,研究了再生混凝土梁的弯曲性能;根据试验结果分析了再生骨料替代率和粉煤灰添加剂对再生混凝土梁开裂荷载和破坏荷载的影响规律。
Based on bending experiment of 10 recycled concrete beams, in which recycled aggregate replacing the natural aggregate and 30 percent fly ash replacing cement, the bending performance of recycled concrete beam are studied;And the regulation of influence of recycled aggregate and fly ash on crack resistance and destroy resistance are analyzed.
