Abstract - The outstanding properties of concrete, such as

silica in the concrete increased, but the concrete's workability also dropped.

its cost-effectiveness, strength, and moldability, account for its widespread use in construction. Concerns over the environmental impact of cement manufacturing, however, drive ongoing research into alternatives. The production of more durable and environmentally friendly concrete, the wise use of resources, and the ensuing decrease in maintenance and life cycle costs can all lead to improved cementitious system performance. The goal of adding ultra-fine additives such as nano-silica to cementitious systems is to improve the characteristics of plastic and hardened materials. The latest advancements in nanotechnology offer promising solutions to these issues. This work explores the simultaneous application of nano-silica (NS) and nano-titanium oxide (NTO) to enhance the mechanical properties and sustainability of concrete.

2. AIM: An experimental study examining how nano-silica and nano titanium oxide affect the mechanical and fresh properties of M-35 grade concrete.

2.1 OBJECTIVE:   

Key Words: traditional concrete, Concrete with Nanosilica and Nano-titanium oxide, Workability, Compressive, Tensile, and flexural strength.

3. LITRATURE REVIEW: G. Dhinakaran et. al. (2014) analysed the microstructure and strength properties of concrete with Nano SiO2. The silica was ground in the planetary ball mill till nano size reached and it was blended in concrete with 5%, 10% and 15% b.w.c. The experimental results showed gain in compressive strength with maximum strength for 10% replacement.

1.INTRODUCTION: The outstanding properties of concrete, such as its costeffectiveness, strength, and moldability, account for its widespread use in construction. Concerns over the environmental impact of cement manufacturing, however, drive ongoing research into alternatives. The production of more durable and environmentally friendly concrete, the wise use of resources, and the ensuing decrease in maintenance and life cycle costs can all lead to improved cementitious system performance. The goal of adding ultrafine additives such as nano-silica to cementitious systems is to improve the characteristics of plastic and hardened materials.

Heidari and Tavakoli (2012) investigated the combined effect of replacement of cement by ground ceramic powder from 10% to 40% b.w.c. and nano SiO2 from 0.5 to 1%. A substantial decrease in water absorption capacity and increase in compressive strength was observed when 20% replacement is done with ground ceramic powder with 0.5 to 1% as the optimum dose of Nano SiO2 particles Alireza Naji Givi et.al. (2012) studied the effect of Nano SiO2 particles on water absorption of RHA blended concrete. It is concluded that cement could be replaced up to 20% by RHA in presence of Nano SiO2 particle up to 2% which improves physical and mechanical properties of concrete.

1.1 Nanotechnology in concrete: The latest advancements in nanotechnology offer promising solutions to these issues. This work explores the simultaneous application of nano-silica (NS) and nanotitanium oxide (NTO) to enhance the mechanical properties and sustainability of concrete. The percentage of nano-silica is 1%, 1.5%, 3% and nano titanium dioxide is 3% 2.5% and 1.0%. Following the experimental examination, the strength of the mechanical qualities increased as the amount of nano-
