Aferição da porosidade do clínquer : uma solução automática

Abstract

Clinker is responsible for 90% of the composition of Portland cement, it is a mixture of clay and limestone. To originate the clinker, it is necessary to heat the mixture so that four main phases appear: alite, belite, aluminate and ferrite; which define its quality. An important aspect of clinker is its porosity, as it influences the quality of the final product. Thus, a technique to monitor the amount of pores in clinker samples is through the observation of microscopic images of the product. Thus, the purpose of this research is to facilitate the work of the quality control professional, contributing to the construction of a computer vision system capable of performing automatic analysis of the samples and decide whether or not it is in a porous state (many pores). For this, image processing and analysis techniques are applied to the images of clinker samples. The techniques studied and tested in this work may be integrated into the system under development in the "Medusa’s Eyes"project, conducted by members of the Innovative Technologies Laboratory, from the Federal University of Ceará Campus, in partnership with the Apodi cement company, located in Quixeré - Ce , Brazil.
