Abstract:
The use of natural eggshells as an additive in concrete has gained attention in recent years due to its potential to improve the performance of the material. The eggshells, which are rich in calcium carbonate, can enhance the mechanical and durability properties of concrete, making it a more sustainable and environmentally friendly construction material. With growing concerns about the environmental impact of traditional building materials, the use of eggshells in concrete offers a promising solution for improving the sustainability of the construction industry. This study aims to explore the effect of eggshell addition on concrete performance, including its impact on strength, durability, setting time, and cost. The results of this research will provide valuable insights into the potential of eggshells as a sustainable alternative to traditional concrete materials. Investigating the impact of adding natural eggshells to concrete mixture on its properties such as compressive strength, split tensile strength, with the aim of determining the potential of eggshells as a supplementary material in improving the performance of concrete. The concrete specimens were prepared with varying percentages of eggshells (4%, 8%, 12%, and 16%) and tested for compressive strength and split tensile strength after 28 days of curing. The results of the study showed that the addition of eggshells to the concrete mixture had a positive effect on its compressive and split tensile strength. The compressive strength of the concrete increased with increasing eggshell content up to 8% and then decreased at higher percentages. The split tensile strength of the concrete also increased with increasing eggshell content. The study concludes that the use of natural eggshells as a supplementary material has the potential to enhance the performance of concrete. The optimal percentage of eggshells for maximum improvement in concrete performance was found to be 8%.
