Analysis of Structural Performance of Fibre Reinforced Sustainable Concrete Using Nano-Engineered Laterite Materials
Abstract
The construction industry is increasingly focusing on sustainable materials to reduce environmental impact and improve durability. This study investigates the performance of nano-enabled laterite infused fibre reinforced sustainable concrete. Laterite soil is used as a partial replacement for cement, while nano-silica enhances microstructural properties and steel fibres improve mechanical performance. Various mixes were prepared by replacing cement with laterite at 10%, 20%, and 30% levels and incorporates 1% steel fibres along with 2% nano-silica, and evaluates compressive, split tensile, and flexural strengths at 7 and 28 days. The results demonstrate that the combination of nano-silica and fibres significantly enhances mechanical properties compared with conventional concrete. The optimal mix containing 20% laterite replacement showed improved strength and sustainability. This study confirms that nano-enabled laterite fibre reinforced concrete can serve as an environmentally friendly alternative for structural applications.
