In this paper an investigational ponder has been performed by substituting the bond with Nano titanium dioxide in the extents of 0.5 %, 1.0 % and 1.5 % (by weight of cement) to enhance the quality attributes of cement with the expansion of Nano titanium dioxide which not just goes about as a channel to enhance the microstructure yet in addition as an activator to advance pozzolanic response there by bringing about the improvement of the mechanical properties of the Concrete blend. The blend configuration utilized as a part of this examination work was PQC M40 for the unbending asphalt and the blend extent of M40 concrete was landed by utilizing IS 10262: 2009 and IS 456: 2000. The specimens (Concrete shapes and bar) were casted, cured and checked following 28 days to investigate out the compressive quality and flexural quality of cubes and beams. The most extreme compressive and flexural quality is accomplished at 1.0 % of Titanium Dioxide (TiO2) with replacement by weight of cement. Key Words: Compressive Strength, Flexural Strength, M40 Grade Concrete, Nano Titanium Dioxide, Nano Concrete. 1. INTRODUCTION Nanotechnology is an innovative technology which deals with the materials of size in a range less than 100 nm. Physical and mechanical properties of the specimens were measured after adding Titanium Dioxide (TiO2) nano particles to concrete. TiO2 nano particle can be used as a replacement of cement (up to 2% weight of cement proportions in concrete) because it could quicken C-S-H gel formation as a result of increased crystalline Ca (OH)2 amount at the early age of hydration and hence increase all the strength of concrete. The nanoparticles benefited in enhancing the porousness and strength of concrete. The three communal stages of titanium dioxide are rutile, anatase and brookite. Rutile is the steadiest form of titanium dioxide. Anatase and brookite are stable at standard temperatures but on heating gradually converted to rutile. In this research attempt the anatase based TiO2 was used. Nanotechnology materials while being combined in constructional structures would not only help in extending their lifetime, but would also keep a check on the energy spent by them and at the same time gauging their reactions and reacting to different agents like fire, corrosion, water penetration, fractures, cracks, etc. Nanotechnology has changed our vision, expectations and abilities to control the material world. Application of titanium dioxide can be used in numerous fields such as it has a wide range of applications from paint, sunscreen to food colorings. It is used for water and air purification has been a subject of extensive research. More recent, the applications have widened to surfaces with self-cleaning, self-sterilizing, bactericidal and anti-fog properties. The purpose of this study is to investigate compressive quality and flexural quality of cubes and beams with different contents of 0.5 %, 1.0 % and 1.5 % by weight of cement. 2. LITERATURE REVIEW Jay Sorathiya, Dr. Siddharth Shah, Mr. Smit Kacha, (2017) research includes an attempt to understand the outcome of Anatase Nano Titanium Dioxide (TiO2) on Conventional Concrete (CC) of M20 grade with various proportions and concluded that the nano-TiO2 particles added concrete had appreciably higher compressive strength comparable to that of the normal concrete. It is found that the cement could be gainfully added with nano- TiO2 particle up to maximum limit of 1.0% with average particle sizes of 15 nm. (Jay Sorathiya, 2017) Iyappan. A.P, Srikanthan.L, Felix Franklin.S, Bhuvaneswari.J, Preethika.A, 2017, studied the use of Nano Titanium Dioxide (anatase based TiO2) of size 15 nanometer (nm) to advance the compressive strength and tensile strength of concrete. An experimental study had been carried out by replacing the cement with nano titanium dioxide. The maximum compressive strength and split tensile strength is attained for 1.5% of Titanium Dioxide (TiO2) with replacement of cement (by weight of cement). (Iyappan.
