Abstract
This paper presents the experimental study on blunder mistakes in testing concrete cubes of grades M25 and M30. Thirty cubes were casted to test the concrete cubes by placing the cubes in compression testing machine as per IS516 - 1959, Cube placed at casted side, Cube placed at outside the circle, Cube placed Diagonally, Cube Misplacement. From this, the test result the misplacement of concrete cube in CTM was given huge difference in strength. More than 8% of strength was decreased when it is misplaced. From this, testing of concrete cubes strength varies from misplacing the cubes in compression testing machine during the application of load. It is suggested to refer the code book before the testing.
