Damage research on the resistance to marine corrosion of recycled concrete

WANG Qian;CUI Qibing;XU Haiqun;Lianyungang Technical College;Lianyungang Water Conservancy Bureau;  
Based on the drying-immersing cycles expriment,the study of recycled concrete with various fly ash contents in seawater erosion is carried out. Under the influence of sea water erosion on the recycled concrete,the compressive strength-time relationship,the relative dynamic modulus of elasticity-time relationship and the mass loss rate-time relationship are obtained. Results indicate that recycled concrete with 40% fly ash content can better resist seawater attack. Meanwhile,through the analysis and study of recycled concrete above all,the damage model is determined with the change in the number of corrosion period.
