Effect on Mechanical Properties and Chloride Penetration Resistance of Modified Hydrotalcite in Cement Mortar
In this paper, two types of modified hydrotalcites (MHT-pAB and MHT-NO2) were incorporated into cement mortars with two dosage levels (replacing 5 and 10 % cement) and a constant water-to-(cement + MHT) ratio of 0.50. Designated testing programme including strength test, porosity test, and rapid chloride migration were employed to investigate the effect of modified hydrotalcites on chloride penetration in cement mortar. The results based on these tests revealed that the incorporation of MHT-pAB at 5 % dosage in mortar specimens produced a notably improved resistance to chloride ingress with no or minor influence on the development of mechanical strength, which further confirmed the possibilities for using modified hydrotalcite as a chloride scavenger in cement mortars.
