Análise das propriedades físicas das misturas cerâmicas utilizadas na indústria de cerâmica vermelha

Abstract

The present work had the objective of identifying the physical properties of the mixtures with 1: 1 and 3: 2 traces of strong clay and weak clay, used in the manufacture of bricks from a red clay deposit located in Itaitinga - Ceará Municipality. The need for improvement in product quality led to an investigation of the characteristics of these traits, establishing the pillars for the development of this work. The ceramic mass was formed in 30 test specimens, with a mold of 117.4 x 25 x 14.6 mm, uniaxially pressed to two tons, being submitted to sintering with a heating rate of 10 ° / min with firing levels of 800 ° C, 850 ° C and 900 ° C, for a period of 1 hour, with 5 specimens for each sintering. The properties determined were: linear retraction of drying, linear retraction of burning, loss of mass, water absorption, apparent porosity and apparent specific mass. The results showed that, according to the statistical analysis (ANOVA), the best trace was 1:1 at 850 ° C.
