The Effect of Layered Double Hydroxides on the Concrete Resistance of Chloride-Ion Penetration

Article Preview

Abstract:

Layered double hydroxides (LDH) can provide the ion-exchange ability and the addition of LDH can affect the chloride-ion transfer in the concrete. The effect of LDH on the chloride-ion penetration is investigated in this study. Concrete samples contained different addition of LDH are designed in the experiment and tested by electric flux method and NT Build 443 method. The experimental results show that the addition of LDH can solidify the chloride-ion in concrete and slow down the transfer of chloride-ion, which enhanced the concrete resistance of chloride-ion penetration.
