【摘要】 由于在工程建设中往往会产生许多的废弃混凝土,对生态环境产生很多不利的影响,为解决这一问题,本文通过向混凝土中掺杂再生骨料的方法,来消耗部分废弃混凝土.同时,为了改善再生混凝土的力学性能,按照相关的试验方法与标准,主要研究了聚丙乙烯纤维对再生混凝土力学性能的影响.试验结果表明:再生混凝土中掺入了聚丙乙烯纤维后,混凝土的抗压、抗拉和变形性能都有所提高.更多还原

【Abstract】 Due to a lot of waste concrete tends to be produced in construction,many adverse effects produced to the ecological environment.In order to solve this problem,the method in this paper is to doping in concrete of recycled aggregate,to consume part of the waste concrete.At the same time,in order to improve the mechanical properties of recycled concrete,this paper mainly researched the effects of polyethylene fiber on the mechanical properties of recycled concrete in accordance with the standard test method.The test results show that polyethylene fibe mixed into recycled concret,its concrete compressive strength,tensile strength and deformation performance are improved.更多还原
