BDA comment on the use of Reclaimed Clay Bricks

The compressive strength of the brick is the most important property of the bricks because brick is mostly subjected to compression and hardly to tension. Bricks are used both for load-bearing structures and non-load bearing structures. Bricks basically used for masonry construction and also used for the construction of brick floors, arches, cornices etc.
