BRICK MASONRY
Taken from : Ambuja Technical Literature Series - 33
INTRODUCTION
Brick is a building material made of hard inorganic clay of a size which can be conveniently handled. Bricks can be easily arranged into various shapes for
most of the structures. The strength of brick masonry works depends upon the quality of bricks, type of bond, proportion and quality of materials used in the
mortar.
Bricks are either made by hand or machine moulded from suitable clay and properly burnt in kilns. Bricks should be sound, hard, homogenous in texture and free from cracks, flaws and modules' of free lime. Bricks are either of deep red, cherry or coffee colour. They must have regular shape and size and should have sharp, square edges and parallel faces. Bricks should be free from pores, chips, flaws or lumps of any kind. When sounded (clapped together) they should give clear metal ringing sound.
Bricks should be provided with frogs. Only full size bricks should be used for masonry work. Bricks bats should be used only with the permission of the Engineers to make up required wall length or for bonding.
REQUIREMENT OF BRICKS
Common building bricks must have a minimum compressive strength of 50 Kg / Sqcm when tested as per IS 3495.
However, the compressive strength of common burnt clay bricks generally vary from 25 Kg / Sqcm to 50 Kg / Sqcm depending upon the technique used to manufacture and the place where it is made. The quality of bricks is generally found to be deteriorating and .hence it is rapidly being substituted by concrete blocks and other materials.
