The physical, chemical composition and service properties of imported monolithic refractory and locally produced refractory lining materials were investigated and compared in this study. The samples were compacted in a standard rammer, cured in air for 24h and oven dried for 24h. They were then heated to temperature of 100°C and characterized to determine their refractory properties. These samples were tested for parameters, such as bulk density, porosity, thermal conductivity, electrical conductivity, refractoriness, permeability, and cold strength. The results obtained indicate that local acidic ramming mass was found to be a good substitute to imported ramming masses due to comparative properties of the former. A fusion temperature of 1620°C was obtained in the local sample which is equivalent to the value obtained for the imported ramming masses. The results of other properties show little or no variation between the locally produced ramming mass and the imported ones.
