FIELD CONSTRUCTION TESTS OF CAST-IN-PLACE CONCRETE PILES USING HIGH-STRENGTH CONCRETE (Fc100N/mm²)

Abstract

Field construction test of cast-in-place concrete piles using high strength concrete (Fc100N/mm²) has been carried out in order to clarify the strength development and the filling ability of concrete. Compressive strength of core specimens sampled from piles was compared with that of simple adiabatic curing specimens and that of standard curing specimens using the same concrete mix proportion. The results indicated that the strength development of high strength concrete constructed under the adequate construction management of cast-in-place concrete pile was very similar to that of high strength concrete of superstructure.
