Abstract

With the construction industry contributing nearly 40% of global greenhouse gas emissions, there is a growing need for innovative and sustainable building materials. This research investigates a new eco-friendly concrete brick incorporating sugarcane bagasse ash (SCBA), sawdust, and bamboo fibers. Three eco-brick mixtures, each containing 2% bamboo fiber and 10% sawdust by weight but with varying proportions of Portland cement (PC) and SCBA, were tested against a standard brick for compressive strength, flexural strength, and water absorption. The optimal mixture, with 2% bamboo fiber by weight, 10% sawdust by weight, 85% PC, and 15% SCBA, exhibits compressive and flexural strength comparable to the conventional brick. While demonstrating lower water absorption than the other eco-brick variants, it falls short compared to the conventional brick. Although further optimization is needed to minimize water absorption, this research demonstrates the potential of utilizing repurposed waste materials like sawdust, bamboo fibers, and SCBA to create sustainable and competitive construction materials. This study contributes to the growing knowledge in sustainable construction by exploring alternative materials that can reduce environmental impact while maintaining desirable mechanical properties.
