TEST OF BRICKS

 TEST OF BRICKS

       There are various field tests in  bricks

 TEST OF BRICKS

• Hardness test
• Soundness test
• Strength test
• Uniformity in size
• Uniformity in colour

     Hardness

           Hardness of a good brick can be tested by making a scratch on bricks surface with the help of finger nail on the field. If no impression is left on the surface, brick is treated to be sufficiently hard. 

     Soundness

         In this test, two bricks are taken and they are strucked with each other on the field. For a good brick a clear ringing sound should be produced. 

Strength Test

     In  this test, brick should not break, when dropped flat on hard ground, from a height of about one metre.

Uniformity in Size

      The brick should be uniform in size and shape and should have rectangular plane surfaces with parallel sides and sharp straight right angled edges. The unifromity in size can be checked out by observing the  bricks on the field.

Uniformity in Colour 

        The brick should have uniform deep red, cherry or copper colour, which can be judged by observing the brick on the field.
