Abstract

This study focused on the characterization, product, and relationship between bending strength and porosity of ceramic bricks with added vermiculite. To achieve this goal, pre-made bodies containing 0%, 10%, and 20% calcined vermiculite by weight were mixed in to create the body compositions. Alumina ball manufactories homogenized fusions (60 rpm, 24 hours) were molded through uniaxial dry pressing (100 MPa). Additionally, the arranged samples were heated to a temperature of 800-1000 °C for a duration of 1 hour. Tests involving phase analysis (XRD), microstructure (SEM), mechanical properties (three point bending), and physical characteristics (Porosity, water absorption, shrinkage and bulk density) were carried out on the demitasse bodies that were manufactured. The data that was collected was displayed in graphs and tables, showing the results. As a result, the packages containing samples of vermiculite were effectively created, and the best parameters were easily displayed. The findings indicate that the quality of flawed packages improves as calcined vermiculite levels rise. Following the characterization results, the correlation between bending strength and porosity was investigated. Correlations, t-tests, and p-values were computed. The inclusion of vermiculite in ceramic bricks results in a significant negative correlation of -0.769 between their bending strength and porosity characteristics.
