Abstract

Concrete is a versatile and resilient construction material widely used in various applications. The incorporation of silica particles, particularly Nano silica, has emerged as a promising approach to reduce cement consumption and enhance the performance of concrete. Nano silica, a type of Nano material, has the ability to modify the molecular structure of concrete, thereby improving its bulk properties and mechanical behaviour. Through its Pozzolanic nature, Nano silica reacts with free lime during cement hydration, results in the development of additional C-S-H gel, which enhances the concrete's impermeability, strength, and durability. This experimental study focused on incorporating Nano silica into M30 Grade concrete at various concentrations (0, 0.5, 1, 1.5, and 2%). The results clearly demonstrate that Nano silica-based concrete exhibits significantly higher strength compared to traditional concrete. These findings highlight the potential and promise of Nano silica-based concrete in advancing concrete technology.
