Bricks are mainly used in construction of wall, floor, cornices and arches. Brick chips are also used as a substitute of stone chips in concrete mix where stone is not available or an economic solution is prefared. In all the above-mentioned cases, compression load governs. Due to this, compressive strength of bricks is a very important parameter.

The strength of a single brick masonry unit varies widely, depending on its ingredients and manu- facturing method. Brick can have an ultimate compressive strength as low as 1,600 psi. On the other hand, some well-burned brick has compressive strength exceeding 15,000 psi. Because portland-cement-lime mortar is normally stronger than the brick ...
2. Crushing Strength or Compressive Strength Test on Brick. Bricks that are used for masonry construction are generally subjected to compressive loads thus it is necessary to determine the compressive strength of bricks. The compressive strength test is also known as the crushing strength test which is an important type of laboratory test conducted on bricks to determine the load-carrying ...
