The growing problem in waste prompted the researchers to use coconut shell as additives in concrete mixture, and to determine whether it significantly increases the flexural and compressive strength of concrete. This study used experimental design to determine the effectiveness of adding crushed coconut shell as additives in concrete mixture.

2022629 · Thus, the eggshell can be used as a replacement for part of the cement. The use of eggshell powder (CaCO3) as a partial replacement for cement improves compressive strength by stabilizing ettringite and monocarbonate [1]. As a rule, the main enterprises that produce eggshells in large quantities are bakeries, restaurants, and …

This research investigated the effect of eggshell powder as a partial replacement of cement on flexural behaviour of a one-way concrete slab. First cement was partially replaced with eggshell powder at these percentage 0%, 3 %, 5 %, 8%, 10%, 13% and 15% (by weight of cement). The resulting concrete was compared for mechanical properties (density, …
