The construction industry is facing major environmental challenges due to excessive cement production and disposal of waste materials. Eggshell waste generated from households, hotels, and food industries creates environmental and disposal problems. Researchers have therefore explored the use of eggshell powder (ESP) as a partial replacement of cement in concrete. This review paper presents a study on the properties, preparation, and utilization of eggshell powder in concrete. Previous research related to workability, compressive strength, split tensile strength, flexural strength, and durability characteristics of ESP concrete has been reviewed and analyzed. The reviewed studies indicate that eggshell powder can effectively replace cement up to 5–10% without significantly affecting concrete performance. Improvement in concrete properties is mainly due to filler effects and improved particle packing. However, higher replacement levels may reduce strength because of insufficient cementitious material. The study concludes that eggshell powder is a sustainable and eco-friendly material that can contribute to waste management and green concrete production.
