Abstract

The choice of appropriate locally sourced refractory materials for lining of locally produced furnaces has remained a major concern in which numerous efforts has been put in place to enhance the performance of the local contents of furnace lining materials. This study investigates the effects of certain additives such as Pulverized Glass Wastes (PGW) and Bentonite on some selected refractory properties of ant-hill clay. 100% finely-ground ant-hill clay, clean water and proportionate amount of Bentonite and PGW were manually mixed, consolidated and oven-dried at 110 oC for a period of 8 hours at varying additives percentages. Compressive strength, apparent porosity, permeability, filtration rate, thermal conductivity and bulk density were experimentally determined... The results showed that the compressive strength, bulk density and thermal conductivity of Ant-hill clay increased significantly on addition of additives while there was corresponding decrease in the values of the filtration rate, apparent porosity and permeability. These values were enhanced by Bentonite and pulverised glass waste additions to the Ant-hill clay. The test results for the compressive strength, thermal conductivity, filtration rate, apparent porosity, bulk density and permeability of no-additive clay samples are 156.4 N/m2 , 0.0028 W/m2K, 0.0041cm3 /s, 0.0009 %, 6.3 g/cm3 and 0.0012 cm/s, respectively. However, the sample-mix consisting 100% ant-hill clay with 80% PGW and 20% Bentonite produced 333.4 N/m2 , 0.0032 W/m2K, 0.0037 cm3 /s, 0.00018 %, 9.5 g/cm3 and 0.0015 cm/s as optimum values for the compressive strength, thermal conductivity, filtration rate, apparent porosity, bulk density and permeability, respectively. Therefore, 80%PGW/20%Bentonite additives gave the optimum results for the production of refractory clay blocks for furnace lining
