Experimental Investigation on Sugarcrete Blocks as a Sustainable Building Material for Low-Rise Construction

The construction industry is a significant contributor to global greenhouse gas emissions, with cement-based materials responsible for approximately 8% of worldwide CO₂ output. In pursuit of more sustainable building practices, this study explores Sugarcrete, an eco-friendly construction material produced from sugarcane bagasse, a fibrous agricultural by-product, combined with natural mineral binders such as lime, clay, and sand. Sugarcrete offers a low-carbon, biodegradable alternative to conventional masonry materials. This research evaluates the feasibility and performance of Sugarcrete blocks for application in low-rise, non- load-bearing construction. Nine different mix ratios were designed and subjected to compressive strength testing, weathering resistance evaluation, and fire resistance assessments. The compressive strength values ranged from 6.81 N/mm² to 7.01 N/mm², confirming its suitability for non-structural masonry. The material exhibited favorable weathering durability and moderate fire resistance, retaining integrity after exposure. The lightweight and thermally insulating nature of Sugarcrete enhances its potential for energy-efficient building systems. This study emphasizes the importance of agricultural waste valorization, contributing to a circular economy by converting sugarcane processing residues into sustainable building materials. The results suggest Sugarcrete as a scalable, eco-friendly, and economically feasible alternative for sustainable construction, with potential for further optimization and integration of other bio-based by-products.
