【摘要】：由于再生砖骨料的特殊性以及多孔混凝土的多孔性,再生砖骨料多孔混凝土的结构和破坏特征与普通混凝土有很较不同。再生砖骨料多孔混凝土应用于工程时,既要保证有较高孔隙率,又要保证其作为护坡结构组成部分的力学强度,为了对该混凝土的结构性能进行分析,设计了控制变量试验,研究骨料粒径、水灰比、目标空隙率对力学性能和透水性的影响,同时设计了正交试验研究上述因素对多孔混凝土性能的影响大小,并得出目标孔隙率对抗压强度和有效孔隙率都有显著影响。分析混凝土抗压强度、实测孔隙率及透水性三者的关系,以三者的平衡点为目标,确定高强度,合理透水性,适于植物生长的最佳配合比。
[Abstract]:Because of the particularity of recycled brick aggregate porous concrete and porous structure, and failure characteristics of recycled brick aggregate porous concrete are obviously different from ordinary concrete. Recycled brick aggregate porous concrete used in the project, both to ensure a high porosity, but also to ensure the slope structure strength part, in order to structure performance the concrete analysis of the control variables, experimental design, study the size of aggregate, water cement ratio, the target the influence of porosity on the mechanical properties and permeability, while the design of the size of the orthogonal test to study the influencing factors on the performance of porous concrete, and the target porosity has a significant influence on the compressive strength and effective analysis of porosity. The compressive strength of concrete, the relationship between the measured porosity and permeability of the three, with the balance of the three as the goal, determine the high strength, reasonable permeability, The optimum mix ratio for plant growth.
