Experimental Study on Strength and Durability Characteristics of Mortars with TiO2 Nanoparticles

The paper briefs about the developments in the construction field with the effective incorporation of different kinds of nanomaterials and their effects on the microstructure, strength and durability characteristics of concrete. The present work gives the detailed procedure for synthesizing the Titanium Dioxide Nanoparticle and strength as well as durability behavior of CM 1:3 is ascertained by partially replacing cement with TiO2 Nanoparticle in varying percentages ranging from 0 to 5 by weight. For better results, TiO2 Nanoparticles were synthesized in the laboratory by precipitation method and were characterized for size, morphology and elemental composition. The characterized SEM results indicated non-uniformity; the Scherrer formula indicated the average size of the Nanoparticle to be 9.61 nm using XRD details. Other results indicate that the cement mortar has shown better compressive strength values and improved resistance against alkalinity and acidity for 3% of TiO2 for 3, 7 and 28 days of curing.
