Abstract: Concrete, the most widely used construction material, confronts durability challenges in aggressive sulfate-rich environments. The reaction between sulfate ions and cementitious materials causes various types of deterioration, such as expansion, cracking, and loss of strength. To address these concerns and promote sustainability, researchers have turned to incorporating mineral waste materials like fly ash and slag in concrete mixes. These by-products not only mitigate environmental impact but also enhance sulfate resistance. This review collates key studies on concrete durability in sulfate-rich environments, with a focus on mechanism of sulfate attacks. Understanding these mechanisms is pivotal in designing sulfate-resistant concrete mixes and ensuring long-term performance in such conditions. The knowledge derived from this review paves the way for resilient and sustainable concrete solutions in sulfate-exposed environments.
Keywords: Concrete, Sulfate Attack, Durability, Mineral Waste, Aggressive Environment.
