Size and Shape Effects on the Compressive Strength of High ...

compressive strength of high strength concrete. We use cylinders and cubes of different sizes for performing stable stress-strain tests. The tests were performed at a single axial strain rate, 10¡6 s¡1. This value was kept constant throughout the experimental program. Our results show that the post-peak behavior of the cubes is

Concrete breakout capacity of cast-in-place concrete ...

concretes were tested at 7, 14, and 28 days at a strain rate of 5 µε/ min. The compressive strength was measured using three 4 in. (100 mm) cubes at each age. Embedded steel bars were used to apply the load. Khan et al. conclud-ed that the tensile-to-compressive strength ratio decreases as concrete matures and the tensile strength gain is similar for a wide variety of mixtures. From this ...
