This study investigates the use of fly ash (FA), rice husk ash (RHA), and marble dust (MDP) in geopolymer bricks, an eco-friendly alternative to traditional brick-making methods Geopolymerization, a process that employs alkali-activated materials to construct solid structures, has shown promise as an eco-friendly alternative to conventional brick-making methods. The researchers created brick samples using different amounts of FA, RHA, and MDP to investigate the properties of geopolymer bricks made with quality materials. To establish the bricks' quality and toughness, tests were conducted on them for efflorescence, water absorption, and compressive quality. After the first 24 hours of treatment, the pace of power rise slowed down to a moderate level. The geopolymer bricks were cured under ambient temperature for 24 hours. This study produced geopolymer bricks using a mixture of FA, RHA, MDP, and an alkali-soda chemical activator solution. The bricks had dimensions of 230mm × 110mm x 75mm. Different proportions of the components were utilized in the mixture, with fly ash comprising 70% to 85% of the combination, fine aggregate accounting for 70% to 95%, rice husk ash ranging from 15% to 30%, and marble dust powder accounting for 5% to 30%. This research's main goal was to determine the effect of these different extents on the properties of the bricks. For each mixture, the concentration of NaOH was maintained at 12M. On the other hand, the sodium silicate ratio was kept constant at 1:2.5. Studies have shown that fine aggregate-constructed geopolymer bricks have greater compressive strength than natural sand. indicating that fine aggregate is a good choice for geopolymer brick production. Using recycled materials as alternatives for burnt bricks in buildings can provide economic and construction benefits. These findings emphasize the significance of future studies into the environmental and economic implications and the durability features of geopolymer bricks. Geopolymer bricks were tested on days 7, 14, and 28 to identify the order in which their overall quality was assessed for strength, air, compressive strength, and water absorption.
