### compressive strength of concrete cube test procedure

Abstract. In this paper we investigate the influence of the shape and of the size of the specimens on the compressive strength of high-strength concrete. We use cylinders and cubes of different sizes for performing stable stressstrain tests. The tests were performed at a single axial strain rate, 10 6 s 1. Shape and size effect has been also investigated about high-strength concrete, showing that size effect is stronger in cubes than cylinders. One of the factors, which change the conversion factors ...
