Abstract
A study about the behaviour of a clay from the Guayabo formation in the Metropolitan Area of San José de Cúcuta when mixed with corundum was conducted; this work is a continuation of others previously performed. In this raw material the dominant minerals are kaolinite and mica; it has quartz, carbonates and free iron oxides, as well as excellent plasticity and a good particle size distribution. Three mixtures with percentages of 5% (M5), 10% (M10) and 20% (M20) of corundum were made using the press technique to form and record control in the drying process. It was sintered in a muffle furnace at 1200°C and 1250°C and tests were performed to determine their technological behaviour, as contractions, bulk density, water absorption, open porosity, mechanical resistance to bending and to deep abrasion. The research results showed that when corundum was added to the clay material, it improves its technological properties, allowing this residue to be used in industrial processes and minimizing the pollution generated by this.
