This construction video tutorial briefly explains what the most important brick test procedures are generally undertaken in the construction jobsite.
The details of the tests are given below :-
Compressive Test – It is performed to verify the strength of a brick. Under this test 5 samples of bricks are chosen randomly and sent them to laboratory and apply pressure on various bricks through a crushing machine. Now, take the average of all the results produced. If the averages is similar to 3.5 N/mm2, the quality of the bricks are good.
Impact Test – This test ensures the proper bond in a brick so that it can’t break easily. Under this test few bricks are selected and dropped them from a height of 1 meter.
Dimension Tolerance Test – In this test shape, size and colors of the bricks are checked. Under this test, 20 bricks are selected and arranged in a straight line. Then we take a sample of standard brick and tally it’s size, shape and color with the bricks arranged in a straight line. If they match with the sample bricks, the bricks should be treated as good quality bricks.
Hardness Test – In this test, a metal or other object is used to put scratches on the bricks. If scratches are not produced, then these bricks are hard and treated as good quality bricks.
