The effect of modified hydrotalcites on mechanical properties and chloride penetration resistance in cement mortar
article
In this paper, two types of modified hydrotalcites (MHT) were incorporated into cement
mortars with two dosage levels (replacing 5% and 10% cement by mass). Designated testing
programme including strength test, porosity test, and rapid chloride migration and diffusion test
were employed to investigate the effect of modified hydrotalcites on chloride penetration in cement
mortar. The results based on these tests showed the incorporation of MHT-pAB at 5% dosage in
mortar specimens produced a notably improved chloride diffusion resistance with no or minor
influence on the development of mechanical strength
mortars with two dosage levels (replacing 5% and 10% cement by mass). Designated testing
