12Apr, 2023 Comprasion of compressive strength of concrete cube and cylinder It is found that cylinder specimen gives lower strength compared to cube specimen. Also, cylinder test gives more uniform strength than cube test. It may be because, The cylinder strength is less affected by the friction at loading surface. The slenderness ratio for cylinder will be more than that of cube (Approximately double, For Cylinder = 300/150 = 2 and for cube 150/150). So, the cylinder has less compressive strength.
