ABSTRACT

The manufacture of the red pottery in the State of Pernambuco (Brazil) is done in the empirical and conservative form. Thus it lacks technological control. The objective of this article is to contribute to the understanding of the current quality of the ceramic blocks used in the civil construction sites in the State of Pernambuco. This article shows an analysis of the composition from the raw material, the process of production and the final quality of the ceramic blocks and prisms from a ceramic specific industry. Visits to this ceramic industry located in the forest zone of Pernambuco gave us the opportunity for understanding the whole manufacturing process, seeing deposits of the raw material and observing its mixture and preparation. For the raw material, the results of granulometrie tests, limits of liquidity and plasticity, specific mass of the grains and moisture are presented. In the case of ceramic blocks and prisms, the tests of compressive strength, intended for non-structural masonry use, were performed.
