Abstract
A process of manufacturing NH2-MIL-125(Ti) for use in mitigating ingress of chlorine ions in concrete, comprising dissolving 2-amino-benzene dicarboxylic acid in a 1:1 ratio of dimethylformamide and methanol, adding a titanium (IV) isopropoxide to the mixture at 150° C. with constant stirring to form NH2-MIL-125(Ti), submerging the NH2-MIL-125(Ti) in dichloromethane for about 3 hours and separating the NH2-MIL-125(Ti). NH2-MIL-125(Ti) produced is activated and ready for use in cement-based concrete structures. NH2-MIL-125(Ti) is enabled to reduce the ingress of chlorine ions in concrete by at least 20%.
Claims14
A method of making a cement-based concrete structure capable of mitigating ingress of chlorine ions, the method comprising:
- providing cement;
- providing NH2-MIL-125(Ti);
- providing water;
- providing aggregates
- mixing the NH2-MIL-125(Ti) with the cement, the aggregates and water;
- allowing the mixture of the NH2-MIL-125(Ti), the aggregates and the cement to set, thereby to form the cement-based concrete structure and wherein an average pore volume of the NH2-MIL-125(Ti) is 0.35 g/cm3″.
