Palm Kernel Ash and Eggshell Ash as Partial Replacement of Cement in Interlocking Brick Production

Abstract

This research uses eggshell ash and palm kernel shell ash as a partial replacement for cement in brick production. Previous researchers have used different materials as a replacement for cement. This research seeks to determine the best eggshell ash and palm kernel ash ratio as a partial replacement for cement in brick production. The experiment uses 5, 10, 15, and 20% eggshell ash and palm kernel shell ash for a partial replacement of cement. This research performs the compressive strength, water absorption, efflorescence, fire resistance, colour, sound and size tests to determine the quality of the brick containing eggshell ash and palm kernel shell ash as a partial replacement for cement. The results show that the best ratio for replacing cement in brick production is 15% eggshell ash and palm kernel shell.
