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.
In order to solve this problem, a lot of waste concrete is often produced in the construction of the project, which has a lot of unfavorable effects on the ecological environment. In this paper, some waste concrete is consumed by doping recycled concrete into the concrete.At the same time, In order to improve the mechanical properties of recycled concrete, the influence of polypropylene fiber on the mechanical properties of recycled concrete was studied in accordance with relevant test methods and standards.The results showed that the compressive strength and compressive strength of recycled concrete after being mixed with polypropylene fiber Pull and deformation properties have improved.
