Bharti Vishwavidyalaya Durg, Chhattisgarh India. ----------------------------------------------------------------***--------------------------------------------------------------------Abstract - The use of nanotechnology has resulted in 1.1 Nanotechnologies in concrete: substantial advances in the concrete industry, ushering in Since its first examination in the late 1980s, the use of novel construction methods. Concrete's application in nanoparticles to improve the mechanical behavior of buildings is due to its low cost, strength, and moldability. cementitious composites has been the topic of ongoing However, environmental concerns drive research into research for nearly two decades. Nanomaterials offer alternatives. Adding ultra-fine additives, such as nano-silica, incredible features and capacities that can improve concrete can improve cementitious system performance, reduce behavior. Nano-SiO2, made up of pozzolanic components maintenance and life cycle costs, and enhance the properties of that react with cement hydration products, is one of the most plastic and hardened materials, resulting in a more widely used nanomaterials. The inclusion of nano-SiO2 sustainable construction process. The most recent improved cement qualities such as compressive and flexural breakthroughs in nanotechnology provide hopeful solutions to strength, resistance to water penetration, sulfate defense, these difficulties. This study investigates the simultaneous use and reduced calcium leaching. Nanotechnology remains a of nano silica (NS) and nano-titanium dioxide (NTiO2) to rapidly growing sector in which researchers from a variety improve the mechanical qualities and sustainability of of industries, including construction, continue to seek concrete. This study investigates the influence of nano-silica breakthroughs. Nonetheless, the -concrete is the world's and nano-titanium dioxide (nano-TiO₂) on the mechanical most used building material due to its low cost and strength. characteristics of concrete. As a result, combining With rising demand each year, over 4.2 billion tons of nanoparticles is more helpful than using them alone. Many cement were manufactured in 2019. It is vital to note that studies support the inclusion of nanoparticles to optimize the the identical materials at the nanoscale have different use of concrete in building structures, both alone and in properties than those at the microscale. This study combination to study the fresh and harden properties of nano investigates of-the simultaneous use of-nano silica (NS) and silica and nano titanium dioxide with partial replacement of nano titanium oxide (NTO) to improve the mechanical cement in different percentage such as 0%, 1% 1.5%, 3%, and qualities and sustainability of concrete. The percentages of 3% 2.5%, 1% are evaluated. nano silica are 1%, 1.5%, and 3%, respectively, whereas nano titanium dioxide is 3%, 2.5%, and 1%.
