摘要
混凝土因具有优异的力学和物理性能广泛应用于建筑行业,但其缺点也很明显,包括负面环境影响和低耐久性。提升混凝土性能以弥补这些缺点一直是该研究领域的热点,在混凝土中掺加天然沸石粉可以有效改善这些问题。讨论了沸石的结构和基本性质,以及作为辅助胶凝材料和内部养护剂在混凝土生产中的应用,分析了沸石对混凝土工作性能、力学性能、耐久性和收缩的影响。
Concrete is widely used in the construction industry because of its excellent mechanical and physical properties,but its disadvantages are also obvious,including negative environmental impacts and low durability.Improving the performance of concrete to make up for these shortcomings has been a hot spot in the research field.Adding natural zeolite powder to concrete can effectively improve these problems.In this paper,the structure and basic properties of zeolite and its application in concrete production as cementitious material and internal curing agent are discussed.The effects of zeolite on concrete workability,mechanical property,durability and shrinkage are analyzed.
