These could lead to natural resource depletion without replacement, resulting in a severe environmental crisis in the future. Because of this risk, alternative construction materials resources must be investigated for replacement purposes. Because cement mortar is a critical element of masonry construction, the rising demand for cement has converted the cement industry into the second greatest greenhouse gas producer, contributing to global warming. Raw material such as eggshells is introduced as a partial substitute for cement in the construction field. Therefore, this paper aims to present mortar's water absorption and flexural strength by incorporating powdered eggshells. Powdered eggshell was used as a partial substitute for cement-based mortar in four mortar mixtures of 0%, 8%, 10%, and 13% of powdered eggshell. A total of 24 mortar cubes were prepared, with six mortar samples for each mixture. All of the specimens are cured in the air. Each mixture of mortar consists of 1 sample for the water absorption test and 5 samples for the flexural test at 24 hours. The result obtained that 13% partial substitution of cement with powdered eggshell produced the highest flexural strength compared to the controlled mixture but only third on the water absorption. The powdered eggshell as a partial substitute for cement in producing mortar still presented the opposite relationship between flexural strength and water absorption, and this experimentation possesses the potential to be used as sustainable construction materials.
