Paper Title:
Influence of Stone Dust Content in Manufactured Sand on Chloride Diffusion Coefficient of C60 Grade Concrete
  Abstract

The influence of stone dust content on chloride diffusion coefficient in C60 grade concrete were investigated by means of the natural immersion test, XRD test, MIP test and TGA test, respectively. The experimental results showed that the chloride diffusion coefficient increased with increasing the stone dust content in manufactured sand, and the chloride diffusion coefficient increased little when the stone dust content increasing from 7% to 13%. The hydration degree for cementitious and compressive strength for concrete was slightly promoted by using stone dust replacing cementitious at a low level. But the porosity and average pore size of concrete increased with increasing the stone dust content from 3% to 13%, and the concrete pore structure was the main factor that influences the changes of chloride diffusion coefficient in concrete.
