Description
Calcium aluminate cements (CACs) are well known for their rapid setting characteristics and refractory performance, owing to their significant early strength gain and excellent thermal stability. The properties of CACs vary based on their alumina content. Global demand for CACs has shown consistent growth in recent years. However, this projected rise in production is likely to intensify the demand for natural raw materials such as limestone and bauxite, thereby increasing the environmental impact-particularly due to emissions associated with limestone calcination. Numerous conventional and alternative raw materials have been identified and studied within CAC technology, owing to their multiple advantages, including cost reduction, lower carbon emissions, and enhanced sustainability. This study tackles the combined challenges of incorporating alternative raw materials and developing hydraulic binders exhibiting diverse hydration characteristics.
