再生骨料混凝土及再生道路材料的研究应用不仅将建筑垃圾有效资源化,而且对社会可持续发展具有重要意义。本文主要针对破碎、处理后的原生骨料的形态和性质进行分析,探讨了再生骨料混凝土的抗压强度、弹性模量、耐久性能等基本性能,分析了再生骨料和砂浆界面微观结构,为高强再生骨料混凝土的研发应用提供了理论依据。 Research and application of recycled aggregate concrete and recycled road materials not only effectively recycle construction waste, but also have great significance for the sustainable development of society. In this paper, the morphology and properties of crushed and treated primary aggregate are analyzed. The basic properties such as compressive strength, elastic modulus and durability of recycled aggregate concrete are discussed. The microstructure of recycled aggregate and mortar interface is analyzed. It provides a theoretical basis for the research and development of high strength recycled aggregate concrete.
