Statistical Analysis of Degradation Data of Red Ceramic Pieces Incorporated with Ornamental Stone Waste

Abstract:

From the point of view of mechanical strength, ceramic materials exhibit dispersion results after being subjected to various levels of stress. However, there are no statistical surveys addressing the results efficiently. The present study aims to conduct with statistically survey, through the Minimum Lot Size, Chauvenet criterion and the Tukey range test. Specifically, the mechanical strength of red ceramic incorporated with ornamental rock waste and fired up to 700°C was analyzed, before and after degradation. The pieces were subjected to degradation of up to 1,500 hours by continuous leaching and of up to 10 months by the natural process. The results of the Tukey Test, before and after the degradation, showed statistical differences, ensuring that the data analysis was effective.
