TEHNOLOGY OF USING FRP, HIGH PERFORMANCE CONCRETE AND ULTRA HIGH PERFORMANCE CONCRETE IN CONSTRUCTION ELEMENTS

Beton je kot konstrukcijski material še vedno najbolj uporabljen material. Betonska konstrukcija, armirana z jeklom, zahteva nenehno vzdrževanje, saj v nasprotnem primeru zaradi korozije betona in jekla armiranobetonski objekti sčasoma propadajo. Polimerni kompoziti ali FRP (ang. Fibre Reinforced Polymers) so materiali, ki se po svetu uporabljajo v vse namene. Vedno več pa se uporabljajo tudi v namene grajenja, saj zaradi dobrih lastnosti konkurirajo armirnemu jeklu v betonskih konstrukcijah. V diplomski nalogi se dotaknem še dveh novejših materialov. Beton visoke trdnosti ter beton ultra visoke trdnosti sta materiala, ki se v svetu gradbeništva še uvajata, vendar že kažeta na odlične lastnosti ter ekonomsko uporabnost. Concrete is still the most used construction material. Steel reinforced concrete structure requires constant maintenance otherwise, due to corrosion of steel, these reinforced structures eventually disintegrate. Fibre Reinforced Polymers (FRP) are materials that are used for all purposes throughout the whole world. Because of their good qualities, they represent great competition with reinforced steel used in concrete structures, and are therefore increasingly used for the purpose of construction. In this thesis I also mention two more recent materials – high performance concrete and ultra high performance concrete. They are only starting to be implemented in the construction industry, but are already showing great potential and economic usefulness.
