【摘要】 试验研究了一种由建筑垃圾混凝土骨料制备的路用透水型彩色再生混凝土的抗压强度、弯拉强度、透水系数。结果表明:水胶比对路用透水型彩色再生混凝土的抗压强度、弯拉强度、透水系数均有明显的影响。添加聚丙烯纤维可以有效增强透水混凝土的弯拉强度,颜料对彩色再生透水混凝土的力学性能影响不显著。更多还原

【Abstract】 The properties of permeable color recycled road concrete fit for medium traffic road were studied through the orthogonal test.The effect of compressive strength,flexural tensile strenth and permeability coefficient on the properties was evaluated.Further,the optimum mixture ratio was gained in terms of the total efficacy coefficient method.The results showed that water binder ratio had obvious effect on compressive strength,flexural strength,permeability coefficient of water permeable color recycled concrete.Adding polypropylene fiber could effectively enhance the bending strength of porous concrete.Pigment content had no impact on permeable color recycled road concrete.更多还原
