Abstract

Vitamin B3 intercalated layered double hydroxides (VB3-LDHs) were added to cement mortar, and thermogravimetric analysis (TGA) and mercury intrusion porosimetry (MIP) were used to characterize the effect of VB3-LDHs on the properties of cement-based materials. Electrochemistry methods were applied to study the corrosion protection performance of VB3-LDHs on steel bars in cement mortar at different ages. The surface analysis of the steel bars was carried out using XPS. The results show that 3% VB3-LDHs have a good anti-corrosion effect, and the corrosion protection performance is substantially better than that of pure VB3. On the one hand, this is due to the dual effect of the slow release of VB3-LDHs and the adsorption of chloride ions. On the other hand, VB3-LDHs can effectively improve the compactness performance of cement mortar. The anti-corrosion effect is not ideal at a content of of 6%, which may be caused by the poor dispersion of VB3-LDHs at a high content. XPS characterization indicated that VB3 can form an organic film on the surface of steel bars.
