Compressive Strength Test (Cube Crushed Test)

ELE compact 1500 machine
This test was done by using a Cube crushed machine named ELE Compact 1500 machine designed for measure compressive strength of materials. Maximum applied load was 2000kN. Samples were taken from the concrete mixture which was used for the construction by making cubes (150mm×150mm×150mm), normally six cubes were made from one sample and it was compacted by using a hammer having 1.8Kg weight when it was making. Three Cubes were tested for strength after 7 days and others in 28 days from particular construction date. For that test a cube was put on the machine which consist a hydraulic jack and then oil valve was closed to take the pressure on jack. After placing the cube, the top screw has to be tightened to touch the upper plate on the specimen. Then adjust the manual display for the test and start the machine for compressed the specimen. When the loading was applying cracks were visible in the cube. When that specimen has reached its maximum load it displayed on the display. The description of the concrete mixture was mentioned on the top face of the each & every cube. All cubes were kept in a tank which was fully saturated by water. According to the testing order cubes were merged in the water in an array.
