摘要:
废旧混凝土的再生利用符合我国绿色环保、可持续发展的基本国策，因此，如何在研究再生混凝土破坏模型的基础有效提高再生混凝土的力学及路用性能进而扩展其在基础建设领域的推广应用是目前亟待解决的问题之一。本文结合国内、外最新研究现状，分别从抗压强度、抗拉劈裂强度、弹性模量等方面对再生混凝土破坏机理、破坏形态研究现状进行归纳总结。此为基础进一步从再生骨料的取代率、骨料类型、试件成型方法、外加剂掺入、钢渣、钢纤维、碳纤维、纤维织物的添加以及粉煤灰或硅粉等矿质填料的加入等再生混凝土力学增强措施研究现状进行梳理与分析。研究成果对加强废旧混凝破坏机理及力学增强措施的研究具有重要的引导作用，为进一步提高废旧混凝的再生利用及广泛推广提供参考。
Abstract:
The recycling of waste concrete was in line with Chinese basic national policy of green environmental protection and sustainable development.Therefore,It was one of the urgent problems to be solved to effectively improve the mechanics and road performance of recycled concrete based on the research of recycled concrete failure model,and expand its application in infrastructure construction.Combined with the latest domestic and foreign research status,this paper summarized the studis of the failure mechanism and failure mode of recycled concrete from the aspects of compressive strength,tensile splitting strength and elastic modulus.On this basis,the replacement rate of recycled aggregate,type of recycled aggregate,specimen forming method,admixture addition,and addition of steel slag,steel fiber,carbon fiber,fiber fabric and addition of mineral fillers such as fly ash or silica powder were analyzed to strength mechanical properties of recycled concrete.The results had an important guiding role in strengthening the research mechanism of waste concrete collapse and mechanical strengthening measures,and provided reference for further improving the recycling and widespread promotion of waste coagulation.
