Study on chloride ion penetration model considering water absorption in concrete

Abstract

The aim of the study is to experimentally clarify effects of water to cement ratio and cement types on chloride ion penetration with water absorption in concrete, and to verify applicability of chloride ion penetration model considering water absorption in concrete. From the experimental result, it is found that capillary water velocity and chloride ion diffusion coefficient correlate highly with continuity pore volume due to effect of water to cement ratio and cement types. And verification result of advection-diffusion model of chloride ion based on experimental result, it is confirmed that this model could evaluate characteristics of chloride ion penetration with water absorption.
