Use of Self-Consolidating Concrete for Bridge Drilled Shaft Construction

One of the primary concerns regarding application of self-consolidating concrete (SCC) in Hawaii has been the development of suitable SCC mixtures using locally available aggregates. Aggregate selection in the Hawaiian Islands is generally limited to crushed basalt for course aggregate and a blend of dune sand and crushed basalt sand for fine aggregate. The high angularity of the crushed basalt aggregates raises concerns over the ability of SCC made with these materials to flow adequately. In addition, the high absorption of these aggregates tends to increase water demand and resulting shrinkage and creep for Hawaiian concretes. Pilot projects by Hawaiian concrete suppliers and precast companies have shown that production of SCC is possible with these aggregates. The objective of the proposed project is to build on these pilot projects to develop comprehensive specifications and mix design guidelines for SCC in Hawaii. The application of these SCC specifications and mix design guidelines would be demonstrated through the use of SCC in drilled shaft construction for the replacement of North Kahana Bridge. Inspections of the SCC during placement, and post-placement inspections, are proposed to evaluate the performance of SCC compared with traditional concrete placement in drilled shafts. The objective of the proposed research is to demonstrate the successful application of SCC to drilled shaft construction on a major bridge construction project in Hawaii. This will include development of the specifications and mix design guidelines necessary to produce an SCC mixture, based on materials readily available in Hawaii, which is suitable for pipe placement in drilled shafts. The placement of SCC in a trial drilled shaft at the replacement North Kahana Bridge will be compared with placement of conventional concrete to evaluate the improvement in performance.
