HIGH-STRENGTH CONCRETE IN TRIAXIAL COMPRESSION BY DIFFERENT SIZES OF SPECIMENS

This paper introduces some experimental data for very high-strength concrete in triaxial compression with very high confining pressures and comparison with available data for different sizes of cylindrical specimens. The experimental data pertain to failure strength and stress-strain curves of high-strength concrete (HSC) in biaxial compression with very high confining pressures by 3-by-6 in. cylinders. Comparisons with the available publications were made. The comparison shows a slight size effect on the failure strength of HSC in triaxial compression.
