UTILIZATION OF FLY ASH AS A CEMENTITIOUS MATERIAL: AN OVERVIEW

The constant cement production results in a rise in carbon dioxide released into the air, which harms the ecosystem and causes greenhouse effects that cause climate change. The establishment of new sustainable material is thus becoming imperative as an alternative to normal concrete. To this end, several studies have been carried out with a partial or total replacement of cement by fly ash. Products with the inclusion of fly ash are considered a relatively new, innovative, and sustainable material with many advantages, including high strength, reduced use of natural resources, costeffectiveness. This study has carried an overview of the utilization of fly ashes in geopolymer, engineered cementitious composites (ECC), roller compacted concrete (RCC), previous concrete, and masonry bricks. The findings showed that the utilization of fly ash to manufacture concrete and masonry products which contribute to sustainable materials and environment-friendly building products.
