摘要
随着人类环保意识的提高和天然砂资源的匮乏,机制砂混凝土在工程中得以广泛应用。现有机制砂混凝土耐久性能研究现状主要集中在影响因素分析方面,其耐久性作用机理研究的不足严重制约着机制砂的推广。本文通过总结机制砂混凝土的抗冻性、抗氯离子渗透性以及抗碳化能力等研究现状,为机制砂混凝土耐久性的系统研究提供参考。
With the improvement of human awareness of environmental protection and the shortage of natural sand resources,mechanical sand concrete has been widely used in engineering.The current research on durability of concrete with mechanical sand mainly focuses on the analysis of influencing factors,and the lack of research on durability mechanism seriously restricts the popularization of mechanical sand.This paper summarizes the research status of frost resistance,impermeability,and carbonation resistance of mechanical sand concrete,and provides reference for the systematic study of durability of machine-made sand concrete.
