Abstract
The effects of curing age and waste material content on mechanical properties and durability of recycled concrete were studied in this paper.The results show that the compressive strength and splitting tensile strength of ordinary concrete and recycled concrete are positively correlated with curing age.The tensile and compressive strength of recycled concrete is lower than that of ordinary concrete,and the tensile and compressive strength of recycled concrete decreases with the increase of recycled material content.With the increase of recycled aggregate content,the chloride ion diffusion coefficient of recycled concrete increases and the permeability becomes worse.With the increase of curing age,the diffusion coefficient of chloride ion resistance gradually decreases,and the permeability resistance begins to increase.Under the water-cement ratio in this paper,the carbonization resistance of reclaimed concrete increases with the increase of curing age and the decrease of waste material content.关键词
