FIELD CONSTRUCTION TEST OF CAST-IN-PLACE CONCRETE PILE USING HIGH-STRENGTH CONCRETE

Abstract

Field construction test of cast-in-place concrete pile using high-strength concrete has been carried out in order to clarify the strength development of high-strength concrete placed with cast-in-place concrete pile construction method. Compressive strength of core specimens sampled from pile concrete was compared with that in full scale model of column 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.
