Influence of an Anti-Chloride Corrosion Admixture on Density of Cement-Based Materials

Article Preview

Abstract:

A new admixture increasing the density of cement-base composites and hence preventing the penetration of chloride ions is developed and investigated. The new admixture is the combination of traditional mineral admixture and steel bar inhibitor. The composition of the admixture is optimized using water absorption tests. Then the effect of the new admixture on the workability of freshly mixed cement paste as well as the pore structure and SEM analysis of hardened cement paste is experimentally investigated. The results show that the new admixture is effective to increase the density of cement-based materials.
