Experimental Study on Chloride Ion Permeability of Steel-plastic Fiber Lightweight Aggregate Concrete
摘要
Abstract
The chloride ion permeability of steel-plastic fiber lightweight aggregate concrete was studied by rapid chloride ion transport coefficient method.The amount of steel-plastic fiber, the type of ceramsite and the time of pre-wetting time of ceramsite were investigated.The research results show that the diffusion coefficient of steel-plastic fiber lightweight aggregate concrete decreases with the increases of fiber content, and the diffusion coefficient is the lowest when the content is 9 km/m3.Compared with fly ash ceramsite, steel-plastic fiber lightweight aggregate concrete that is made the shale ceramsite has lower diffusion coefficient.The pre-wetting time of ceramsite has little effect on the chloride ion diffusion coefficient of steel-plastic fiber lightweight aggregate concrete.However, the diffusion coefficient in the lightweight aggregate concrete increases with the increases of the pre-wetting time.关键词
