Abstract

Nano-TiO2 is one of the most common materials used in paints as pigment because of its various advantages. Nano-TiO2 can be used as filler material in concrete for filling several intervals in concrete such as flaws, voids, fissures, bleeding channels, etc. By filling such intervals, the strength of concrete can be improved. In the present work, it is aimed to study the performance of M40 grade standard strength concrete with the use of nanomaterials by replacing the cement partially with nano-titanium dioxide (TiO2) (ranging from 0.5 to 2%). The workability of M40 grade concrete with and without incorporating nano-TiO2 has been studied by conducting slump cone test and compaction factor test. Finally, the strength characteristics of both the concrete have examined by performing compression, split tensile and flexural tests. The application of nanotechnology by incorporating nanomaterials in concrete has added a new dimension to improve the mechanical properties of the concrete. Workability is decreased with the increase in replacement, and strength is increased up to 1% replacement of cement. Based on the experimental results, it was noticed that at 1% replacement of cement, the compressive strength of the concrete was increased by 8% when compared to the conventional concrete. This concrete is used at the places where high strength and low permeability are required.
