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.

Abstract in Filipino [Abstrak]

Umaabot sa halos 40% ng global greenhouse gas emissions ang naidudulot ng industriya ng construction, tumataas ang pangangailangan para sa mga inobatibo at sustainable na materyales sa construction. Sinuri sa pag-aaral na ito ang makabagong eco-friendly concrete brick na binubuo ng sugarcane bagasse ash (SCBA), sawdust, at bamboo fibers. Tatlong eco-bricks mixtures ang pinag-aralan, bawat isa ay may 2% bamboo fiber at 10% sawdust batay sa bigat, ngunit may magkakaibang proporsyon ng Portland cement (PC) at SCBA, at inihambing sa karaniwang brick batay sa compressive strength, flexural strength, at water absorption. Makikita sa mga resulta na ang pinakamainam na mixture, na may 2% bamboo fiber, 10% sawdust, 85% PC, at 15% SCBA, ay may compressive strength at flexural strength na maihahambing sa karaniwang brick. Bagama’t mas mababa ang water absorption nito kumpara sa ibang eco-brick variants, hindi ito umabot sa antas ng conventional brick. Sa kabuoan, batay sa mga resulta, ipinapakita ng pag-aaral ang potensiyal ng paggamit ng mga repurposed na materyales tulad ng sawdust, bamboo fibers, at SCBA sa pagbuo ng sustainable at matibay na construction materials. Gayunpaman, kinakailangan pa ng karagdagang pagpapaunlad upang mabawasan ang water absorption. Nag-aambag din ang pag-aaral sa paglawak ng kaalaman sa sustainable construction sa pamamagitan ng pagsusuri sa mga alternatibong materyales na maaaring makabawas sa epekto sa kalikasan habang napapanatili ang kanais-nais na mechanical properties.
