摘 要:利用正交试验分析了制备透水砖过程中花岗岩骨料粒径、集灰比、水灰比、生石灰掺量等因素的影响并对其重要性进行排序。研究了各因素与抗压强度、抗折强度、透水系数和孔隙率的关系。讨论了静压成型压力和振动成型时间对孔隙率和透水系数的影响。根据混合材料最优配比参数,完成了制作透水砖的最佳配合比设计方案。试验证明:经加工处理后的花岗岩石材边角废料是制备环保型透水砖的有益材料。
Abstract: The effects of granite aggregate size, aggregate cement ratio, water cement ratio, lime dosage, etc. on performance of water permeable brick were analyzed by using orthogonal test and the importance of these factors were ranked. The relationships of orthogonal factors and the performance such as compressive strength, flexural strength, permeability coefficient and porosity were researched. The influence of static molding pressure and vibration molding time on the porosity and the permeability coefficient was discussed. The best mix design for making permeable brick was completed according to the optimal ratio of mixtures. The test results prove that: the leftover waste material granite after processing is a good material for preparing environmental permeable brick.
