Brick

====A brick is a block of ceramicmaterial. Bricks for building may be made from clay, shale, soft slate, calcium silicate, concrete, or shaped from quarried stone. However, true bricks are ceramic, and therefore created by the action of heat and cooling.==== ====Bricks are used for building, block paving and pavement. They are used in masonry construction, usually laid using various kinds of mortar. It has been regarded as one of the longest lasting and strongest building materials used throughout history.====

 * ==== What is the meaning of //brick laying techniques//? ====

They are the different methods used by the persons in order to lay bricks to construct brickwork such as walls.
==== Structural bond refers to how the individual masonry units interlock or tie together into a single structural unit. You can achieve structural bonding of brick and tile walls in one of the following three ways: Overlapping (interlocking) the masonry units, e mbedding metal ties in connecting joints or using grout to adhere adjacent wythes of masonry. Mortar bond refers to the adhesion of the joint mortar to the masonry units or to the reinforcing steel. ==== ==== The running bond is the simplest of the six patterns, consisting of all stretchers. Because the bond has no headers, metal ties usually form the structural bond. The running bond is used largely in cavity wall construction, brick veneer walls, and facing tile walls made with extra wide stretcher tile. ==== ====Masonry is a composite material consisting of masonry units and mortar joints. This not only accounts for its inherent appeal, but can also be its inherent weakness. The achievement of an effective bond between the brick and mortar is the most important aspect of masonry construction, and this bond is reliant on the workmanship and mortar ingredients. Mortar is also relatively weak compared to bricks so the removal of the traditional 10mm joint, not only increases the speed of construction, it also drastically improves the strength of the masonry.====
