1. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels
Master-uppsats, KTH/BetongbyggnadSammanfattning : The dominating support method for hard rock tunnels today is use of fibre reinforced shotcrete in combination with rock bolts. The fibre reinforced shotcrete secures smaller blocks, while rock bolts are used to support larger blocks in the rock. Application of shotcrete is done by spraying against the rock surface using compressed air. LÄS MER

3. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken
Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanikSammanfattning : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. LÄS MER
4. Laboratory testing of shotcrete with fibres of steel, basalt or synthetic materials
Master-uppsats, KTH/BetongbyggnadSammanfattning : Shotcrete or sprayed concrete has become an inevitable material for stabilising and supporting hard rock tunnels. To prevent rock block fallouts in the excavated tunnel, shotcrete is pneumatically projected under high pressure on the rock surface. LÄS MER
5. Seismic evaluation and retrofitting of an existing building in Athens using pushover analysis
Master-uppsats, KTH/BetongbyggnadSammanfattning : Earthquakes are one of the biggest problems in civil engineering all over the world. Due to earthquakes, great disasters in cities with collapsed structures and human losses have been caused. LÄS MER
