INCREASE OF FLEXURAL STRENGTH OF RED CERAMIC PIECES INCORPORATED WITH ORNAMENTAL ROCK WASTE: APPLICATION OF WEIBULL STATISTIC FOR DETERMINATION OF BEST FIRING TEMPERATURE

摘要

Ceramic materials exhibit dispersion results after being subjected to various levels of stress, from the point of view of mechanical strength. With the focus on sustainable development and to improve the strength of these material, was incorporated ornamental rock waste into clay in up to 10% in mass to conform some samples, that was fired to 750°C, 850°C and 950°C and submitted to technological tests. This paper presents an analysis of the technological properties of the samples through the use of Weibull statistic to determine which the best firing temperature for these red ceramic materials. The Weibull Modulus indicates a greater homogeneity for samples with 10R at 950°C.
