摘要
本文综述了近年国内外关于CO_(2)养护固废材料体系协同增强机理的研究进展,CO_(2)矿化养护技术运用在各种固废胶凝材料和CO_(2)之间的碳酸化反应和产物沉积过程实现产品力学强度等特性的提升,本文主要从CO_(2)养护技术对固废胶凝材料的影响、CO_(2)养护的现状及进展展开叙述。重点描写了CO_(2)养护对固废胶凝材料的孔隙率、力学性能、耐久性的影响,并最终对CO_(2)养护固废材料体系作出前景和建议阐述。
This paper reviews the research progress of CO_(2) curing solid waste system synergistic strengthening mechanism at home and abroad in recent years.CO_(2) mineralization and curing technology is applied in the carbonation reaction and product deposition process between various solid waste cementing materials and CO_(2) to improve the mechanical strength and other properties of products.In this paper,the influence of CO_(2) curing technology on solid waste cementitious materials,the status quo and progress of CO_(2) curing are described.The effects of CO_(2) curing on the porosity,mechanical properties and durability of solid waste cementitious materials are described in detail,and the prospects and suggestions of CO_(2) curing solid waste material system are presented finally.
