Abstract

This report describes the result observed during the practical application of shotcrete including silicafume in the Gorigamine tuunel.The experiment is designed so as to confirm the workability and quality of the shotcrete composite with silicafume, which has been already confirmed in laboratory test by the authors. According to the examination, it is observed that the shotcrete including silicafume has following characteristics; the range of slump to reduce the quantity and rebound ratio is comparatively wider than that of conventional shotcrete;the existence of minute particles of fine aggregate is effective to improve the construction performance of the shotcrete.
