Formulation of ceramic body to produce roofing tiles using Winkler diagram

Abstract

Winkler diagram was the tool used to formulate roofing tiles ceramic bodies using three different clays. The objective was to obtain a ceramic product with good technological properties using local clay that has deficiencies in its chemical-mineralogical composition. Specimens were made by uniaxial press-molding at 35MPa and then fired at 850 °C. The technological properties determined were flexural rupture strength, water absorption and linear shrinkage. The results showed that local clay has excessive coarse particles that impossibility its roofing tiles production and confirming the need to make a blend with other plastic raw materials. The Winkler Diagram was effective in the formulation of ceramic bodies due to the improvement of the observed properties.
