多孔混凝土力学破坏机理及其改性研究

摘要

The main research object of this test is the compressive failure of porous concrete,including the failure mechanism of porous concrete and the modification of porous concrete.The results show that the destructive properties and the effect are obvious dif-ference between the porous concrete and the traditional concrete.And most of the damage layers are distributed at the bonding layer between the aggregate and the cementitious material of porous concrete.Also interface transition layer of concrete,and the interface op-timization method proposed not only effectively improves the physical properties of porous concrete,but also improves the interface transition layer.%以多孔混凝土抗压破坏行为为研究对象,对多孔混凝土破坏机理进行分析研究,并在破坏机理研究的基础上,进行多孔混凝土改性研究.试验结果表明:多孔混凝土的破坏性质及效果与传统混凝土存在明显差别,大多数破坏层均分布于集料与胶凝材料的结合层处,即集料与胶凝材料相连接的界面过渡层处;提出的界面优化型拌合方法有效的提高了多孔混凝土的物理性能,并且较好的改善了界面过渡层.
