Influence of TiO2 on the Physical and Mechanical Properties of Cement Mortars: A review

This study explores the impact of Titanium dioxide (TiO2) as an additive on the physical and mechanical properties of various types of cement mortars. It delves into the strengths, durability, and workability under normal conditions and challenging environments like different temperatures, CO2 exposure, as well as optimal TiO2 dosages either alone or in combination with other additives. The results indicate that TiO2 is a filler in cement mortars that enhances strength and decreases permeability by improving the hydration process and increasing density. It improves water absorption, electrical resistivity, and resistance to acid and chloride attacks but reduces workability. However, as the TiO2 percentage rises, the resistance and durability of cement mortars decrease. This paper offers valuable knowledge for civil engineers to establish the most effective proportion of TiO2 and its utilization in conjunction with other additives. Furthermore, researchers can leverage this paper to pinpoint areas for further investigation in this domain.
