Assessment of the effect of Nano particles on physical and mechanical properties of high grade self-compacting concrete.

Abstract

Concrete that can be poured and compacted under its own weight with little to no vibration and without bleeding or segregation is known as self-compacting concrete (SCC). The use of SCC in concrete manufacturing is growing daily due to its improved production techniques. Recently, nanoparticles have gained greater interest due to their unique physical and chemical properties, and they are being exploited in many different fields to develop novel materials with creative uses. . Using a logical mix design, M60 grade self-compacting concrete was created in this project. 1%, 1.5%, and 2% of nano silica in a colloidal condition with 30% nano content was added to SCC. To support the novel features of SCC, tests such as the L-box, V-funnel, J-Ring, and slump flow were carried out and compared to the EFNARC (2005) requirements. Compressive, split tensile, and flexural strengths are among the strength characteristics of M60 grade SCC at 3, 7, and 28 days, both with and without nanoparticles (SiO). In comparison to the SCC without nanoparticles, it was determined that the SCC with silica nanoparticles exhibited superior strength characteristics. According to test results, adding nanoparticles to concrete has enhanced its performance in a number of strength-related areas.
