20.500.12556/DiRROS-21849 Evaluation of the performance of clay-based bricks with the addition of co-combustion ash The gradual replacement of coal by local renewable resources leads to an increased production of co-combustion ashes (CC). Their disposal can be limited by their use in the construction sector, where they can partially replace primary raw materials. This study evaluates the incorporation of selected Slovenian CC ash into clay-based fired bricks within the EU AshCycle project. The tests included the measurement of water absorption, porosity, density, weight loss, shrinkage, flexural and compressive strength, and freeze-thaw resistance. Two types of clay were used to compare the influence of the selected ash on the performance of the fired samples. Replacing clay mixtures with 10 wt% CC ash reduced the compressive strength of the fired bricks but it still reached the required 10 MPa as specified in EN 772-1 (2015). The addition of CC ash to fired bricks requires careful planning of the raw mixes, taking into account various parameters that may affect the properties of the products. fired clay bricks waste ashes raw mixture ceramic-technological tests freeze-thaw resistance žgane opeke odpadni pepeli surovinska mešanica keramično-tehnološki testi odpornost proti zamrzovanju odpornost proti zamrzovanju / taljenju true false true University of Maribor, University Press Angleški jezik Slovenski jezik © 2025 Univerza v Mariboru, Univerzitetna založba Neznano 2025-04-07 12:15:13 2025-04-07 12:19:48 2025-10-24 03:49:59 0000-00-00 00:00:00 2025 0 0 Str. 169-179 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-03-03 54 230880515 227616771 https://press.um.si/index.php/ump/catalog/book/949/chapter/250 1 32bd6ba5-1399-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31507 http://hdl.handle.net/20.500.12556/DiRROS-20922 Raziskovalni podatki 0 33b2eeb4-1399-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31508 RAZ_Zibret_Lea_2025.pdf RAZ_Zibret_Lea_2025.pdf 1 A207A19BE81FED54C021BC4FCFB169BE e050c9d2168e413872c6513ea4cc65b1a6f45d77e51925eee14d144a50a63318 d1a16f04-1399-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31509 Zavod za gradbeništvo Slovenije Dataset for the conference paper Evaluation of the performance of clay-based bricks with the addition of co-combustion ash 0 0 0
