Crushing strength is 175kg/cm 2 (mean) where the minimum is 154 kg/cm 2. It emits a metallic sound when struck by another similar brick or struck by a hammer. It is hard enough to resist any fingernail expression on the brick surface if one tries to do with a thumbnail. It is used for the construction of one-storied buildings, temporary shed when intended durability is not more than 15 years ...

To determine the compressive strength of burnt clay building blocks THEORY Brick are mostly subjected to compression and rarely to tension. The usual crushing strength of common hand molded well burnt brick is about 5 to 10 N/mm2 (50 to 100kg/cm2) varying according to the nature of preparation of the clay. Pressed and machine molded bricks made of thoroughly mixed clay are much stronger …

Compressive Strength of a brick is determined by placing a brick in the compressive testing machine and loading the top face (frog face) till failure. The brick frog face if filled with mortar and cured for a period of 4 days before. A minimum compressive strength of 3.5 N/mm2 should be obtained as per IS codes. If the compressive strength of the brick is less than 3.5 N/mm2, those bricks ...
