Cenospheres are waste products produced during the burning of coal to create electricity. These wastes can be combined with cementitious ingredients to create lightweight materials. Furthermore, the integration of these wastes can help to improve the thermal and acoustic qualities of cementitious materials. However, the addition of these cenospheres changes other features. This research provides a comprehensive analysis of the characteristics of cementitious materials that contain cenospheres. A brief description of the origin, physical features, and chemical properties of cenospheres was initially presented. The impact of cenospheres on physical, mechanical, and durability properties also addressed.
