Abstract

This study investigated the recycling of ceramic kiln room waste as broken refractory bats, bricks and props for the production of refractory kiln props used as kiln bat footings in ceramic firing operations.Waste refractory materials were processed and blended with kaolin, ball clay, and silica to develop a refractory body suitable for kiln-prop production.Test props were formed, dried, and fired to approximately 1200°C.The results showed that the recycled composite body produced kiln props with satisfactory strength, moderate shrinkage, and resistance to warping and cracking during firing.The study demonstrates that ceramic waste from the kiln room can be effectively reused in the manufacture of kiln props, thereby reducing waste generation and dependence on imported refractory products.
