聚丙烯纤维及橡胶颗粒对透水混凝土性能的影响
Effects of Polypropylene Fiber and Rubber Crumbs on Performance of Pervious Concrete
摘要
Abstract
It based on the influence factors of polypropylene fiber and rubber crumbs, researched the influence factors by measuring compressive strength and flexural strength at 28 d,the porosity, permeability coefficient of pervious concrete,and got the relationship between the dosage of polypropylene fiber and rubber particles and mechanical performance and the permeability performance of the pervious concrete.The test results showed that when the particle size is 4.75-9.5 mm,the compressive strength and the flexural strength at 28 d of the pervious concrete were improved,but the permeability coefficient were decreased.Compared with the addition of rubber crumbs,the mechanical properties of pervious concrete can be improved more obviously in adding polypropylene fiber.And with the increase of the proportion of polypropylene fiber and rubber crumbs, the increasing extent of the compressive strength and the flexural strength at 28 d of pervious concrete gradually lessen,but the permeability coefficient were decreased gradually.关键词
