Optimization of Axial Tension Test for Cement Composites

5.12.2016 | Ing. Martin Tipka, doc. Ing. Jan Vodička, CSc., ČVUT v Praze, Fakulta stavební, Katedra betonových a zděných konstrukcí
The paper introduces modified arrangement of the test in axial tension for cement composites. Specific shape of the specimen and special steel grips to fix the specimen in testing machine are described. The arrangement of the test enables recording of the load-deformation diagram in the central part of the specimen and direct derivation of the stress-strain diagram.

Retenční schopnosti testovacích segmentů zelených střech

5.12.2016 | Ing. Klára Nečadová, Ing. Petr Selník, Ing. David Bečkovský, Ph.D., doc. Ing. Jan Pěnčík, Ph.D., Fakulta stavební - VUT Brno
Green roof is currently very discussed topic especially their positive retention properties in urban units. The article describes tests of three diverse variants of green roofs applied on the testing building EnviHUT in Brno – research centre AdMaS. Each roof set represents unique application of structural and physical characteristics, but also different characteristics of biological and botanical aspects. With respect to these facts it has been provided and tested optimal design type of green roof that would secure a long-term stability corresponded to local parameters. The article also focuses on the discussion between the participants of the implementation process of vegetative parts of buildings, including a link to the issue of building legislation.
