Description
The current global tendency in the construction industry is to replace a portion of the cement in the concrete mix with materials of cementitious properties to mitigate the cement industry’s negative environmental impact. This study explores using finely milled Mechanized-Fired Clay Brick debris to partially replace Portland cement in the production of mortars. The principal aim is to create a more costeffective mortar for non-structural uses while also tackling the problem of disposing of waste bricks. Two samples of Mechanized-Fired Clay Brick were collected from two different factories, pulverized into a fine powder, and added to the cement mortar mixtures in 10%, 15%, and 20% by mass of cement. Mortars were examined for their chemical composition, fineness, consistency, and setting time. Furthermore, the compressive strength of the mortar specimens at 3, 7, and 28 days was tested. Results showed that the strength activity index of both samples exceeded 75% at 7 days and reached nearly 100% in 28 Days. This confirmed the suitability of mechanized-fired clay brick to be used as a supplementary cementitious material.
