再生骨料混凝土抗氯离子渗透性能研究进展
Research Progress on the Chloride Permeability of Recycled Aggregate Concrete
摘要
Abstract
Chloride-induced corrosion is one of the main factors affecting the durability of concrete structure.Before the recycled aggregate (RA) is used as a structural material,it is necessary to clarify the chloride permeability of recycled aggregate concrete (RAC).The mechanism of chloride permeability of RAC was analyzed from the characteristics of interfacial transition zone,and the influence of many factors,such as RA replacement rate,water-to-cement ratio,admixture,construction technology,stress level,on the chlorine permeability of RAC was summarized.And the improvement effect of RA modification on chloride penetration resistance of RCA was described.Finally,it is pointed out that the further investigation on the chloride permeability of RAC under multi-factor coupling action is requisite and significant.关键词
