Effect of Materials and Construction Conditions on Shotcrete Quality
초록
Recently, TBM (Tunnel Boring Machince) method for a tunnel construction in domestic is very promisible due to shorten a constrution period. It is very important to increase the efficiency of the shotcrete for the TBM. The major factors influencing the efficienty of shotcrete are materials, mix disign, constrution conditions and skill of nozzle-man. In this paper, first, optimum synthesize conditions for the shotcrete accelerators was explored and early stiffenting mechanisms also studied. Second, TBM method was applied for a real job site using the optimum conditions obtained from a lab scale experiment.
