eggshells for traditional concrete constituents should be determined through experimentation and testing to achieve the desired performance and durability characteristics. Eggshells can be used as a sustainable additive in concrete production, contributing to both environmental conservation and improved material properties. II. OBJECTIVES
Egg shells are a rich source of minerals, serving as a pharmaceutical excipient, a base material for developing medicinal and dental preparations, a food additive and calcium supplement, a diluent of solid dosage forms, use as an agricultural fertilizer component, and as a component for bone implants (Murakami et al., 2007).
Research on the reuse of waste materials in the concrete industry has been quite intensive in the past decade. The objective of this research is to identify the performance of …

Calcination is a process used to prepare nano-CaO ESP [70], [71], as shown in Eq. (1). Restaurants, houses, and bakeries frequently discard eggshells. After collecting the eggshells, they are cleaned and dried for 24 h in an. Slump. The slump test results of concrete mixes incorporating ESP at distinct replacement levels have been listed in ...
The study and use of seafood especially the shell of oyster as an additive material for ceramic tiles. According to Hung-Yu Wang (2013), oyster shells can be utilized for producing medium- and high-quality cement. In other studies, for potential use, the shells are mostly used as additive or replacement of part of the cement
