Abstract:
This presentation will compare the long-term changes in the porosity and diffusion coefficient of belite CSA cements and compare the results to portland cement, calcium sulfoaluminate, and alkali activated binder. The results will also show that the addition of a pore blocking admixture will greatly reduce the diffusion coefficient with only minor impact on the porosity. The findings suggest that early age durability testing of belite CSA cements may not be appropriate.
