Abstract
This article presents experimental study to analyse the effect of pre-compressive loading on the chloride permeability of concrete used in anti-permeable admixture; the admixture was mixed in concrete with compression resistance of 30 MPa for casting specimens. Specimens was pre-compressive loaded at different stress levels including values in elastic phase and in diffused damage phase. After reloading, specimens were treated and put into measurement cell for chloride permeability evaluation. The results show significant effect of pre-compressive stress on chloride permeability of concrete, especially when damage appeared. effect of anti-permeable admixture on concrete permeability was also clarified.
