Abstract

In Nigeria, importation of several additives usually used in blending fireclays is on the increase. Similarly, other materials available in the country are currently underutilized. These materials could be used as additives to alter/improve the refractory properties of fireclay. The performance behavior of refractory bricks produced from a single and multi-component blending of Osiele and Ikorodu fireclays with Azara-Lafia zircon was studied. The chemical compositions of the raw materials were determined using the Atomic Absorption Spectrophotometer (AAS-PG990AFG). The Osiele and Ikorodu fireclays were blended with Azara-Lafia zircon at varying mass proportions of 10 -35%. The blended samples were mixed with water (3 -4%), molded into bricks using the Hydraulic Press (Paul-Weber D-7084) to 300KN. The bricks were air dried for 24 hours and later fired in the Carbolite RHF-16/15 furnace at 800oC to 1200oC. Cold crushing strength test were conducted using Testometric M-500-30KN D7940.
