固体废弃物在蒸压加气混凝土中的应用现状综述

摘要/Abstract

摘要： 随着固废资源化利用成为当下研究的热点,近年来采用固体废弃物制备蒸压加气混凝土的研究成果层出不穷。但固体废弃物由于种类繁多,特点不一,对蒸压加气混凝土的干密度和抗压强度等关键性能的影响规律和影响机理并不明晰,亟需进行归纳总结。本文首先从基体和孔结构两方面分析归纳了影响蒸压加气混凝土干密度和抗压强度的主要因素,之后从固体废弃物做硅质材料、钙质材料和发气材料三个方面分析了其对蒸压加气混凝土干密度和强度的影响规律和影响机理,最后总结了当前研究中存在的问题并对未来的研究方向进行了展望。

关键词: 蒸压加气混凝土, 固体废弃物, 硅质材料, 钙质材料, 发气材料

Abstract: With the utilization of solid waste resources becoming a hot topic nowadays, the research outputs of autoclaved aerated concrete prepared by solid waste are endless in recent years. However, due to the wide variety and different characteristics of solid wastes, the laws and mechanisms of solid wastes affecting the dry density, compressive strength and other key properties of autoclaved aerated concrete are not clear, which need to be summarized urgently. This paper first summarized the main factors affecting the dry density and compressive strength of autoclaved aerated concrete in terms of matrix and pore structure, and then analyzed the rules and mechanisms of solid wastes influencing the dry density and strength of autoclaved aerated concrete in terms of siliceous, calareous and gassing materials, finally summarized the problems in the current research and discussed the future research directions.

Key words: autoclaved aerated concrete, solid waste, siliceous material, calcareous material, gas forming material
