چکیده مقاله:
One of important causes for failure of concrete structures particular in Persian Gulf region is diffusion of chloride in concrete .One of the parameters which can increase the diffusion chloride ion is level of diffusivity of the concrete. prediction of concrete diffusion factor is an important issue as a key parameter in life cycle of concrete structures. Experimental method in this field have problems such as time consummation, high cost, lack of experimental instruments, existence of inconvenience ions during experiment, committing unwanted errors and distorting from the true model. For this reason in this research singular value decomposition (SVD) for modeling the diffusivity of chloride ion in concrete has been used. The aim of this modeling is to find mathematical relation between the concrete diffusivity coefficient with effective parameters on it which means the proportion of water per cement and percent of silica fume.
