Bazaltna armatura za ojačenje betonskih konstrukcij

diplomska naloga

Anja Opara (Author), Drago Saje (Mentor)

Abstract

Diplomska naloga v prvem delu opisuje relativno nov material, ki bi lahko v prihodnosti zamenjal jekleno armaturo v betonskih konstrukcijah. Bazaltne palice imajo v primerjavi z jeklenimi visoko odpornost proti koroziji. Poleg tega so izredno lahek material z visoko natezno trdnostjo. Z vidika dimenzioniranja je neugoden nizek modul elastičnosti, kar pomeni, da imajo palice manjšo togost. Zaradi manjše togosti konstrukcijskih elementov se v primerjavi z jekleno armiranimi elementi povečajo pomiki in razpoke. Predpis Evrokod ne vsebuje navodil za projektiranje betonskih konstrukcij, ojačanih z bazaltno armaturo. V drugem delu naloge so predstavljena obstoječa navodila za dimenzioniranje upogibno obremenjenega nosilca po ameriških standardih in primer dimenzioniranja prostoležečega betonskega nosilca, ojačanega z bazaltno armaturo.

Secondary title:	Basalt rebar for reinforcing concrete structures
Secondary abstract:	The first part of the graduation thesis describes a relatively new material. In the future steel reinforcement in concrete structures is supposed to be substituted by basalt reinforced rebars. They have higher corosion resistance than steel reinforcement. Additionally, basalt rebars are extremely light in weight with high tensile strength. However, modulus of elasticity is extremely low, which can be a problem in view of construction design. Due to lower modulus of elasticity stiffness is reduced. Higher deformations and wider cracks are formed. Eurocode standards do not provide guidelines for designing a basalt reinforced concrete beam. In the second part, the existing American guidelines for the design of structural concrete with fiber reinforced polymer bars are presented. There is also an example of designing a basalt reinforced concrete beam.
