Abstract

•9 concrete mixtures with different W/B ratios and admixtures were designed, exposed up to 600 d.•The analytical method of instantaneous diffusion coefficients was studied.•Influence of W/B ratio, admixture and exposure time on the age reduction factors were analyzed.•Time dependent model of instantaneous diffusion coefficients of chloride was validated.•The chloride diffusivity of concrete tends to be stable basically after 360 d exposure time.
