Review on Enhancing Durability of Concrete Using SCBA and Hydrated Lime as Cementitious Additives

This study investigates the potential of using Sugarcane Bagasse Ash (SCBA) and hydrated lime as supplementary cementitious materials (SCMs) to enhance the mechanical and durability properties of concrete. SCBA, a by-product of the sugar industry, is rich in silica and exhibits pozzolanic characteristics, while hydrated lime improves workability and resistance to chemical attacks. The research explores how SCBA and lime, when combined, can partially replace Ordinary Portland Cement (OPC) in concrete, leading to a reduction in environmental impact and enhancing concrete performance, especially in harsh conditions such as sulfate-rich environments. The findings indicate that SCBA, particularly when processed optimally, can improve concrete’s strength, durability, and resistance to chemical assaults. This study contributes to the development of more sustainable and eco-friendly concrete solutions, promoting greener construction practices.
