Utilization of Glass Powder and Eggshell Powder as Fine Aggregate in Making Bricks

Masonry structures, traditionally made with bricks, face raw material depletion. There is a need to, explore sustainable alternatives like glass and eggshell powder to replace traditional fine aggregate. The literature indicates the potential use of these materials in replacing fine aggregates. Materials including cement, fine aggregate, glass powder, and eggshell powder are characterized for various properties. Bricks were cast using different proportions of these materials and evaluated. The properties of bricks with glass and eggshell powder are compared to conventional ones for water absorption, initial rate of absorption, compressive strength, modulus of elasticity, masonry efficiency, and ultrasonic pulse velocity tests. Thus, utilizing these waste materials in construction can prove sustainable. Since this research demonstrates that the necessary mechanical properties—most notably, compressive strength and efficiency—are improved, these bricks can be used commercially.
