Production and characterization of aluminosilicate refractory brick using Unwana beach silica sand, Ekebedi and Unwana clays has been carried out with a view to determining the suitability of localy available raw materials for refractory bricks production. The sand was used to compose six (with 65%, 60%, 55%, 50%, 45%, and 40% of Unwana beach silica sand) refractory brick body together with Ekebedi and Unwana clays. The properties of the produced bricks investigated after firing shows that samples A - F had total shrinkage ranging from 3.2% to 8.3% with % porosity of 16.58 to 18.66 respectively. The bulk density result revealed that Samples A- F had 1.63g/cm3 to 1.53g/cm3 with compressive strength ranging from 7.90Mpa to 21.49Mpa respectively. The estimated refractoriness result indicated that the samples A-F had values ranging from 16080C to |
