Abstract

Cement production generates nearly one ton of carbon dioxide for every ton manufactured, contributing significantly to environmental degradation. Geopolymer concrete, which incorporates industrial by-products, for example, fly ash, metakaolin, and ground granulated blast furnace slag, offers a sustainable alternative. This study explores the use of stone quarry dust as a replacement for natural sand in brick production. A blend comprising 70% metakaolin, 30% ground granulated blast furnace slag, and stone quarry dust, activated with sodium silicate and sodium hydroxide, yielded bricks with high compressive strength, minimal water absorption, and excellent acid resistance. These eco-friendly bricks provide a cost effective, durable alternative to conventional bricks, making them suitable for diverse environmental conditions.
