  1. 1. Environmental and technical evaluation of cement reduction and test methods for fibre reinforced shotcrete in tunnels

    University essay from KTH/Betongbyggnad

    Author : Elin Brodd; Lina Östlund; [2022]
    Keywords : Shotcrete; Global Warming Potential; Environmental Product Declaration; Tunnel construction; Fibre reinforcement; Compressive strength; Residual strength; GGBS; Sprutbetong; Klimatpåverkan; Miljövarudeklaration; Tunnelbyggande; Fiberarmering; Tryckhållfasthet; Residualhållfasthet; Granulerad Masugnsslagg;

    Abstract : 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. READ MORE
