A vantagem do processo de fabricação de tijolos com manipueira é ser ecologicamente correto, pois não consome água, nem há necessidade de ir ao forno, economizando recursos naturais e fazendo uso de um efluente altamente poluente. Assim, este trabalho objetivou analisar as propriedades mecânicas de tijolos fabricados com solo associado à manipueira como alternativa sustentável. Foram avaliados os parâmetros absorção de água e resistência à flexão. Em conformidade com os resultados, observou-se que as massas cerâmicas apresentaram valores de absorção de água da ordem de 10 a 13 %, valores aceitáveis para fabricação de blocos cerâmicos e valores de resistência a flexão adequados para fabricação de tijolos maciços, tanto, os corpos de prova com queima quanto os corpos de provas sem queima. Assim, conclui-se que a troca da água pela adição da manipueira na massa cerâmica não interfere nas propriedades mecânicas e esta pode ser adicionada a massa cerâmica para fabricação de tijolos ecológicos através do processo de prensagem.Mechanical properties of manufactured bricks with soil and cassava wastewaterAbstract: The advantage of the manufacturing process of brick with cassava is being environmentally friendly because it does not consume water, and there is no need to go to the oven, saving natural resources and making use of a highly polluting effluent. This work aimed to analyze the mechanical properties of bricks made from soil associated with cassava as a sustainable alternative. Parameters were evaluated water absorption and flexural strength. In accordance with the results, it was observed that the ceramic material provided water absorption values of the order of 10 to 13%, acceptable values for manufacturing ceramic blocks and bending strength values suitable for manufacture of solid bricks, both proof bodies test with burns as the proof bodies of evidence without burning. It is therefore concluded that the replacement of water by the addition of cassava the ceramic mass does not interfere with the mechanical properties and that can be added to the ceramic paste for manufacturing green bricks through the pressing process.

Much industrial waste has mineralogical, chemical and physical characteristics similar to clays used in ceramic materials, enabling the reuse of these as raw materials in the ceramic industry. The ashes are a type of waste containing metals, which can cause air pollution, responsible for serious respiratory problems in the affected population. This study investigate the use of waste derived from the carbonization of a solid fuel (wood) in ceramic paste used for the manufacture of rustic floors, aiming its incorporation into the mix, partially replacing (lessening the environmental problem) the usage of raw material (saving clay), enabling the analysis of certain variables of sample preparation (characterization and formulation) and their influence on the final properties of the material. Results indicate that the partial replacement of clay by ash is feasible in the chemical and mineralogical aspects in the formulation of ceramic paste in the manufacturing of rustic floors.

The article is about republication of the complex of the building ceramics from the excavations of the «cave town» Eski-Kermen. At the first time this complex was published in 1941 by N. I. Repnikov, who was the author of the excavations, and in the 1950 and 1979 by A. L. Yakobson. This researcher made the complex of roof tiles an important part of his medieval building ceramics investigation. The central peculiarity of these works was a special attention for the craft marks on the tiles and ignorance of common forms and ceramic paste of the tegulaes and imbrexes. Such approach led to serious mistakes in the tiles dating. The republication of this complex based on the modern methodology of roof tiles analysis is an important step for correction of these mistakes and for mainstreaming of its scientific significance. As a result roof tiles from the excavation of the Eski-Kermen were listed by the morphological and technological features and drawn with the accuracy. Instead of small-scale pictures of craft marks without the tegula background as in previous works, this publication presents pictures in scale 1 : 4, where the smallest details of the production were represented in full-size. This methodology showed its positive results in the work with the building ceramics from Eski-Kermen. There are three main branches of these results. At first, the work with the roof tiles from excavation of the Eski-Kermen in 1936—1937 showed mistakes in the pictures of the craft marks in the A. L. Yakobson works. One of the craft mark with the complex design was separated into the two parts, which were dated differently. At-second, some craft marks, which were absent in N. I. Repnikov and A. L. Yakobson works, were published for the first time. The craft mark with the ship and fantastic beast is the most significant of it. At-third, the tegulaes from the N. I. Repnikov excavations were dated according to the technological and morphological classification and by the findings some analogies from modern excavations. The chronology of tiles proposed in this work is demonstrated that the excavations on the Eski-Kermen in the 1936—1937 discovered stratigraphy contexts of the four periods: IX—X c., X — first half of the XIII c., the second half of the XIII c. and XIV c., which weren’t described by N. I. Repnikov.

Abstract This paper aims to present a state of the art of additive manufacturing (AM) of ceramic materials based on extrusion processes of clay pastes, reviewing the definitions and classifications of the AM field under current international standards. A general overview on the AM category ‘material extrusion’ is provided and the class ‘paste deposition modeling’ is proposed for those techniques based on the extrusion of pastes that are solidified by solvent vaporization, with the aim of distinguishing it from the class ‘fused deposition modeling’, which is applied to extruded polymers through temperature plasticization. Based on the survey of background information on 3D printing technology by ceramic paste extrusion, a classification and historization of the innovations in the development of this technology are proposed.
