| Popis: | Opisana su istraživanja primjene polipropilenskih vlakana u mikroarmiranom betonu za sekundarnu tunelsku oblogu tunela Sveti Rok. Posebno su prikazana istraživanja žilavosti i otpornosti takvog betona na djelovanje požara. Istaknuto je da takav beton ima povećanu otpornost na udar i habanje, mraz i soli te povećanu vodonepropusnost. Preporučuje se primjena toga za primarnu i sekundarnu oblogu tunela, što povećava vatrootpornost, smanjuje mikropukotine, a povećava trajnost. The analysis of the use of polypropylene fibers in fiber reinforced concrete for the secondary lining of the Sveti Rok tunnel is presented. A special emphasis is placed on the study of toughness and resistance of such concrete to fire action. It is stressed that this type of concrete has an increased resistance to impact and wear, frost and salt, and is much more impermeable to water. Its use is recommended for the primary and secondary tunnel lining, as this will result in higher fire resistance, reduced microcracking, and increased durability. |
