A Comparative Study Of The Mechanical Properties And Water Absorption Of Different Masonry Bricks In Egypt

Abstract

To evaluate existing structures and guide future strengthening initiatives, as well as to comprehend the mechanical characteristics and percentage of water absorption of different masonry bricks that are often utilized in Egypt. The experimental program encompassed ten distinct types of brick units included: first-class perforated clay bricks, second-class perforated clay bricks, first-class cement bricks, second-class cement bricks, autoclaved aerated concrete (AAC) brick, sand-lime bricks, engineered perforated clay bricks with horizontal holes, and engineered perforated load-bearing clay bricks., with a total of one hundred and fifty brick units investigated. These brick units were meticulously examined to measure their compressive strength, flexural strength, and water absorption properties. The findings of this study highlighted that solid sand-lime emerge as an optimal choice for constructing load-bearing walls in Egypt according to its remarkable compressive strength. As well as second-class perforated clay bricks has higher flexural strength and its cost-effectiveness make it particularly an optimal choice for constructing masonry elements subjected to flexure. These insights provide valuable guidance for builders, engineers, and architects alike.
