摘要:
以水泥细石透水混凝土为基层材料、树脂砂基混合料为面层材料,制备复合结构生态透水砖(EPBCS).通过分析树脂、水泥、有机物X及石英粉对复合结构砂基透水砖的抗折强度、抗压强度,以及透水系数的影响规律,确定透水砖的基本结构和组分,并对其透水机理进行分析.研究表明:掺入4%石英粉作为矿物外掺料,可以在保证树脂砂基混合料强度的基础上有效改善材料的透水性能;当树脂掺量为3%~5%时,有利于面层砂基混合料力学性能的改善;当树脂掺量为5%,石英粉掺量为4%,以及体积分数10%的有机物X掺量为2%,基层透水混凝土的主要组分掺量为细石∶水泥∶水=3.0∶0.8∶0.3时,复合结构生态透水砖的抗压强度高于25.0 MPa,且透水系数均高于2.3×10-2 cm·s-1,满足相关规范对一般透水砖的性能要求.
Abstract:
Taking cement pervious concrete with fine stone as base material, and resin-sand mixture as surface material, these two kinds of materials were used to prepare the ecological permeable brick with composite structure(EPBCS). The basic structure and composition of EPBCS were designed by analyzing the effect of resin, cement, organic-X and quartz powder on the flexural strength, compressive strength and permeability coefficient of EPBCS; and the permeability mechanism was studied. It is shown that: on the basis of guaranteeing the basic mechanical properties, adding 4% quartz powder improves effectively the water permeability of resin-sand mixture; adding 3%-5% resin improves the mechanical properties of resin-sand mixture. Adding 5% resin, 4% quartz powder, 2% organic-X with 10% concentration, and ratio of the main components of base permeable concrete is that fine stone∶cement∶water =3.0∶0.8∶0.3, the compressive strength of all the specimens of EPBCS exceeds 25.0 MPa, and the permeability coefficients are higher than 2.3×10-2 cm·s-1, which meets the requirements of relevant specifications.
