Lehký beton z pórovitého kameniva s rozptýlenou výztuží

Concrete masonry is relatively low in cost due to the wide availability of aggregates used in the production process. These aggregate materials are not always suitable for structural use. The common solution to the issue of brittle concrete element characteristics is addition of steel reinforcement. However, this solution can be expensive, highly dependent on the quality of the labour and especially on the quality of the available steel. A possible alternative to conventional steel reinforcement has proven to be the addition of steel fibres to the concrete mix. By adding steel fibres to lightweight aggregate concrete, research has shown an increase in flexural strength, toughness, and ductility. The paper deals with the topic of lightweight aggregate concrete reinforced with fibres, especially in terms of physical properties, with special regard to the reinforcement of steel fibres.
