Title: Tunnel Concrete--Consolidation Achieved by a Harmonic Blend of Internal and External Vibration
Author(s): T. R. Harrell and G. M. Goswick
Publication: Special Publication
Appears on pages(s): 103-118
Keywords: concrete construction; consolidation; fresh concretes; permeability; placing; surface defects; tunnel linings; vibration; vibrators (machinery); Manufacturing
Abstract:The permeability of a tunnel concrete lining can be significantly affected by the consolidation techniques and procedures used during a concrete placement. Both the density and the durability of the concrete will have an influence on the ultimate permeability of the concrete. Consolidation techniques and procedures that will include both external and internal vibration can be used to aid in obtaining a concrete lining, which may be characterized as slightly permeable. Techniques and procedures used for consolidation of the tunnel lining concrete for the Rocky Mountain Pumped Storage Project are presented and discussed.
