Study on Permeability of Concrete under Sustaining Tension
An experimental device which provided uniaxial sustaining tension stress to concrete was especially designed with pressed spring. The accelerated, steady state chloride migration experimental method was used to test the permeability of concrete under tension resulting from designed device. Concrete with two mixture proportions was tested to get chloride diffusion coefficient under different tension stress. Mathematics models were built to show the change of chloride diffusivity coefficient of concrete under tension.
