The physical (ceramic aptitude) and chemical (X-ray fluorescence) properties of four raw materials were analyzed (Peracos clay, La Alejandra clay, Kaolin HS-801 A and mixes Tachira). Measurement indicators were obtained through the studied temperatures (1150 and 1280 oC) to identify its composition and the individual behavior; and select the amounts to be used in the formulation of the different mixtures: MA, MB, MC, MD, ME and MF. Finally, the most appropriate mixtures for the manufacture of a refractory brick prototype were used to real scale. The mixture MA presented a low percentage of contraction in stew of 2.89 at the temperature of 1280 oC, a constant apparent density of 1,60g/cm3 and resistance to the break of 16.98Kgf/cm2. MB presented a low percentage of contraction in stew of 5.69 to the temperature of 1280 oC, an apparent density of 1.58g/cm3 and a resistance to the break of 49. 01 Kgf/cm2, and ME presented a low percentage of contraction in stew of 5,88 to the temperatureof 1280 oC, an apparent density of 0.93g/cm3 and a resistance to the break of 7,68Kgf/cm2; those that fulfill the conditions required by NTC 623 for the refractory brick manufacture.
