Evaluating resistance of fine bone china ceramic aggregate concrete to sulphate attack

This study deals with the results of sulphate attack on concrete containing fine bone china ceramic aggregate (BCFA). Natural river sand in concrete was substituted by 0%, 20%, 40%, 60%, 80% and 100% fine bone china aggregate. The concrete specimens were submerged in 3% MgSO4 solution for 7, 28, 90 and 180 days. The influence of sulphate solution was evaluated by change in mass and change in compressive strength. Studies related to microstructure like FT-IR and XPS were carried out to monitor the influence of BCFA in sulphate resistance of concrete.
