Abstract
about the properties of most available clay materials in Nigeria is necessary to enhance their industrial applications. Availability of this information will adversely reduce importation of refractory materials and its products into the country, since the mineral resources are abundantly available in the country. This study evaluated the chemical and physico-mechanical properties of some selected clay deposits across the three districts of Asa Local Government Area (LGA) of Kwara State to ascertain their suitability for refractory and other industrial applications. The results revealed that the clay samples were mainly alumina-silica based with silica and alumina concentrations of 47.30 – 58.50% and 32.75 – 34.30% respectively. The physico-mechanical properties exhibited by the clay samples included: clay content (33.80-72.20%), linear shrinkage (6.10-9.80%), moisture content (21.00-33.00%), bulk density (1.99 - 2.87 g/cm3), apparent porosity (21.00-37.00%), permeability (73-94), compressive strength (213-840 N/mm2), thermal shock resistance (+29 cycles), specific gravity (2.18-2.52) and refractoriness (>1300oC). The properties were within the required standard values which make the clays suitable for insulating materials, refractories for low-medium thermal applications and
