Abstract
A cement-talc-chamotte refractory mixture was dosified by subjecting the same to thermal shock. To this end, specimens compacted to 350 Kg/cm 2 through compression as well as specimens compacted manually were prepared. All the specimens were submitted to an initial working temperature of 1000°C and then left to cool down to room temperature. The thermal shock was originated by heating the specimens in an oven till reaching a certain temperature T i and then quenching the same through immersion in water at 20°C; temperature T i was varied between 170°C and 970°C by means of 100°C increments. The optimum dosification amounting to 90% cement-talc and 10% chamotte was obtained by studying means stress at compression fracture of five cement-talc-chamotte mixtures as a function of thermal shock. In addition, thermal fatique exhibited by the optimum dosification was studied through the determination of mean loss in compressive strength, which amounted to 52% after 7 cycles with ΔT = 500°C.
