Abstract

The construction industry consistently pursues sustainable and new materials to improve the performance and durability of infrastructure. This study examines the efficacy of nano silica, a residual substance derived from industrial operations, in the context of road infrastructure development. Nano silica possesses exceptional pozzolanic qualities that can enhance the mechanical and durability attributes of concrete. This study assesses the influence of nano silica on the performance of concrete utilized in highway pavements by conducting a series of laboratory tests and field testing. Important factors such as the ability to withstand compression, the ability to resist tension, the ability to withstand bending, and the ability to remain durable under different climatic circumstances are tested and analyzed. The findings demonstrate that the addition of nano silica greatly improves the compressive and tensile strengths of concrete, as well as strengthens its resistance to abrasion and chemical assault. The study also examines the environmental advantages of using micro silica, emphasizing its potential to decrease the carbon emissions associated with roadway construction. The findings indicate that nano silica is a highly promising material for constructing durable and environmentally-friendly highway infrastructure, as it provides enhanced performance and ecological advantages. Potential areas for future research involve the extended evaluation of field performance and the investigation of the most effective blending proportions for different roadway uses.
