Abstract: Concrete has a significant impact on the environment as the cement, whose production involves a large amount of CO2, is its main ingredient. Enhancing the durability limitations of the concrete structures can reduce their impact on the environment. Incorporating a small amount of Nanoparticles in concrete can modify the Nano-structure of cementitious materials, and thus procure high durability. Nano Silica on the strength properties, durability limitations, and microstructural individuals of the concrete. The replacement level was varied from 2% to 5% in PPC. Cement is replaced by 2%, 3%, 4%, 5% of Nano Silica and 2% of Nano Silica is increased in Compressive Strength of concrete 40%. Crimped Steel Fibre are considered by high tensile and flexural strengths and high ductility, as well as by a high compressive strength and a very good workability. Durability and strength of concrete can be better-quality at lower fibre contents, where fibres are used in combination rather than reinforcement with a single type of fibre. Crimped Steel Fibre has been used with replacement of cement by 1.5% and 1.5% of Crimped Steel Fibre is improved in Compressive Strength of concrete 48%.
