English abstract
This paper focuses on the need for domesticating the production of building materials like tiles to address the problem of Nigeria over dependence on imported goods, despite adequate availability of mineral resources like clay, quartz and feldspar in the country. Clay, quartz and feldspar, and milled glass were respectively obtained from Ogijo in Ogun State, Okpila in Edo State and Oshodi, Lagos State of Nigeria were characterized using ASTM C71 as a guide. Samples of the ceramic tile were produced from varying mixtures of clay, quartz, feldspar and milled glass. The chemical and physio-mechanical properties of the samples were also determined. The results showed that the clay sample belong to Alumino-silicate group with 59.20% silica and 21.25% alumina. The samples' properties met the required standards; hence, the materials were found suitable for production of ceramic tiles of acceptable standards. Though, the porosity of the sample tiles increased as the percentage weight of the clay material in the mixture decreased the proportion of quartz, feldspar and milled glass increased. The sample containing 70% Clay and 30% Feldspar had better formulation properties than others.
