| 摘 要： | 泡沫混凝土是我国水泥基建筑材料的重要组成部分,分析了孔结构的分类及其对泡沫混凝土的强度、耐久性、保温系数等宏观性能的影响,发现泡沫混凝土的宏观性能与孔结构密切相关。总结了泡沫混凝土孔结构的控制技术,发现水灰比、矿物掺合料等的加入都会影响孔的形成。在此基础上,提出加强对建立孔结构与宏观性能之间的理论模型、孔结构与宏观性能间关系的适用范围、孔的定量控制等方面的研究。

| Abstract: | Foam concrete has become an important component of cement-based materials.The classification of pore structure,and its influence on the properties such as strength,durability,and thermal properties are described.Also the method of controlling pore structure is showed,discovering that adding w/c ratio and mineral will affect the formation of pore structure.Based on that,deeper research in the theoretical models of pore structure and macro pro-perties,the applicability of pore structure and macro properties,the definite quantity control of pore structure are proposed. |
