Abstract

Abstract

Influences of water to cement ratio (w??c) and cement content on concrete durability are analyzed in detail based on experimental results. An initial chloride effective diffusion coefficient predicting model is proposed according to nonlinear least square method regression. This model can be used to evaluate the initial chloride effective diffusion coefficient which takes combination influences of w??c and cement content into consideration. At last, relevant validation experiments are executed to test the regression model.
- cement content,
- chlorideion,
- initial chloride effective diffusion coefficient
