Fly Ash Characteristics - A Challenge or Opportunity for Utilization
Abstract
This article explores fly ash, a coal combustion byproduct, and its potential applications in sustainable engineering. Classified as Class F with pozzolanic qualities or Class C with self-cementing capabilities, fly ash is used in construction, environmental cleanup, and innovative materials. It also has potential for climate change mitigation and the circular economy. However, it faces issues like leaching, compositional variability, and economic feasibility. To overcome these, advanced characterization methods, innovative activation approaches, and joint research are suggested. Fly ash integration into sustainable construction, carbon capture, and circular economy principles requires ongoing study and development based on its chemistry. Future research objectives include chemical activation, life cycle assessments, new energy storage, and nanotechnology usage.
