Abstract
The technology of production of ceramic roof tiles on the basis of low-melting red-burning clay, namely on the basis of clay from the Sadovoye deposit of the Sverdlovsk region, is proposed. The samples of ceramic roof tiles, molded by plastic and semi-dry way, were obtained with the properties that meet the requirements of Russian standards and correspond to the quality of the Röben ceramic roof tiles. The water absorption of such products is 6.2–6.9%, the apparent density is 2.19–2.31 g/cm3, the products are waterproof for more than 4 hours, and withstand frost resistance for more than 150 cycles. The production technology involves the use of high-speed firing way in the temperature range of 1150–1200°C. The production technology provides for grinding the clay to a grain size of less than 0.3 mm. Molding of products can be done both in a plastic or semi-dry way. The use of high-speed firing is allowed. There is no destruction of products made on the basis of Sadovoye deposit clay.
Highlights
Ceramic roof tile has significant advantages over other types of roofing in terms of architectural expression, durability, and in other physical and mechanical characteristics
The properties of ceramic roof tiles produced by Röben were studied in order to compare their properties with the obtained samples based on clay from the Sadovoye deposit
Conclusion the possibility of obtaining of ceramic roof tiles based on Sadovoye deposit clay was established
Summary
Ceramic roof tile has significant advantages over other types of roofing in terms of architectural expression, durability, and in other physical and mechanical characteristics. The modern building materials market of the Russian Federation includes ceramic roof tiles from various manufacturers, such as: Terreal (plants Tuiles Lambert, TBF and Guiraud Fréres – the oldest French brands in the production of ceramic tiles and bricks), Röben (Robin or Rebon) [9] in Sroda – Slinska (Poland), CREATON is one of the largest European manufacturers of ceramic tiles (Germany), Ludowici – USA, Tejas Cobert Company (Spain, Portugal), KORAMIC – Austrian concern “Wienerberger”. The cost of such roof tiles is 20–76 $ per 1 m2
