Eggshell (ES) is a bio-waste material obtained from bakers and fast-food restaurants. This waste material is generally disposed of in landfills, causing health hazards and polluting the environment. Eggshell powder (ESP) has high amounts of calcium and can be combined with pozzolanic materials, such as fly ash, which have low calcium content. This paper presents the results of the latest studies on the utilization of ESP as a filler, cement and fine aggregate. The chemical composition, physical properties and fresh and hardened properties of ESP concrete at different proportions are also presented. Results indicate the potential of using ESP with other pozzolanic materials to improve concrete properties and reduce cement production, thereby minimizing environmental pollution. The compressive, flexural and tensile strengths have also been improved with the use of some materials with ESP as cement replacement. However, some studies reported a reduction when cement is replaced with high percentages of ESP, particularly those larger than 10%. Furthermore, the modulus of elasticity decreases with high levels of replacement. The specific gravity of ESP was found to be lower than that of cement. The durability and water absorption of concrete were reduced with the addition of ESP.

蛋壳（ES）是从面包师和快餐店获得的生物废物材料。这种废料通常被丢弃在垃圾填埋场中，造成健康危害并污染环境。蛋壳粉（ESP）含有大量钙，可以与钙含量低的火山灰材料（例如粉煤灰）结合使用。本文介绍了利用ESP作为填料，水泥和细骨料的最新研究成果。还介绍了不同比例的ESP混凝土的化学组成，物理性能以及新鲜和硬化性能。结果表明，将ESP与其他火山灰材料一起使用可改善混凝土性能并减少水泥产量，从而最大程度地减少环境污染。压缩的 弯曲强度和抗拉强度也得到了改善，因为使用了某些用ESP代替水泥的材料。但是，一些研究报告说，用高百分比的ESP（尤其是大于10％的ESP）代替水泥时，水泥的减少。此外，随着高水平的替换，弹性模量降低。发现ESP的比重低于水泥的比重。添加ESP会降低混凝土的耐久性和吸水性。
