摘要
本文研究了再生粗骨料掺量、再生细骨料掺量、粉煤灰取代水泥量和水灰比对再生混凝土抗压强度和坍落度的影响。正交试验表明,再生粗骨料的掺量是影响再生混凝土强度和坍落度的主要因素;通过正交分析,提出了再生混凝土的最佳配合比,并选出强度和坍落度均比较高的三组混凝土做耐久性的试验研究。
The effect of recycled coarse aggregate quantity,recycled fine aggregate,PFA replacing cement quantity and water cement radio on the recycled concrete compression strength and slump.Orthogonal experiment results show that recycled coarse aggregate quantity is the main factor that influences recycled concrete compression strength and slump.The optimum mix radio of recycled concrete is advanced by orthogonal analysis.And I studied on the durability of three groups of recycled aggregate,which compression strength and slum Pis are high.
