钢纤维再生混凝土的力学性能研究进展

Research progress on mechanical properties of recycled aggregate concrete reinforced with steel fibers

再生混凝土能有效解决施工产生的建筑垃圾处理问题,实现资源回收再利用。然而,天然缺陷严重影响再生混凝土在实际工程中的推广应用。作为一种新型复合材料,钢纤维再生混凝土(掺入钢纤维后的再生混凝土)研究逐渐成为复合材料领域一个研究热点,也取得了一定的研究成果。为了推进钢纤维再生混凝土的实际应用进程,拟从力学性能研究方面对钢纤维再生混凝土的研究现状与发展趋势进行综述分析,并指出今后尚待探讨的研究问题。

Recycled aggregate concrete can effectively solve the problems to disposal the construction waste,and achieve the recycling of resources.The natural defects of recycled aggregate concrete seriously affect its application in practical engineering.However,as a new type of composite material,the research on recycled aggregate concrete reinforced with steel fibers（recycled aggregate concrete was added steel fibers）has gradually been a hot topic in the field of composite materials and some achievements has been made in this field.In order to promote the applications of recycled aggregate concrete reinforced with steel fibers in the practical engineering,it summarized the ralative research resutls and analysized the current situation and development trend in the perspective of the mechanical properties of recycled aggregate concrete reinforced with steel fibers,and pointed out the research problems to be carrided out in the future.
