Brick

A brick is a ceramic piece obtained by cooking, drying and modeling at high temperatures, its dimesions usually are: 24x12x6. Bricks are usually used in the constructions of facades and walls. There are eight types of brick, the various types differ in their formation and composition. - Building brick, also called common, hard, or kiln-run brick, is made from ordinary clay or shale and is fired in kilns. These bricks have no special shoring, markings, surface texture, or color. Because building bricks are generally used as the backing courses in either solid or cavity brick walls, the harder and more durable types are preferred. - Face brick is better quality and has better durability and appearance than building brick. Because of this, face bricks are used in exposed wall faces. - Clinker brick is overburned in the kiln. Clinker bricks are usually rough, hard, durable, and sometimes irregular in shape. - Pressed brick is made by a dry-press process, rather than by kiln firing. Pressed bricks have regular, smooth faces, sharp edges, and perfectly square corners. Ordinarily, they are used like face brick. - Glazed brick has one surface coated with a white or colored ceramic glazing. The glazing forms when mineral ingredients fuse together in a glasslike coating during burning. - Fire brick is made from a special type of clay. This clay is very pure and uniform and is able to withstand the high temperatures of fireplaces, boilers, and similar constructions. - Cored bricks have ten holes—two rows of five holes each-extending through their beds to reduce weight. Walls built from cored brick are not much different in strength than walls built from solid brick. - Sand-lime brick is made from a lean mixture of slaked lime and fine sand. Sand-lime bricks are molded under mechanical pressure and are hardened under steam pressure.

Now im going to tell you about bricklaying techniques. Bricklaying is a trade that specialises in building and repairing walls, floors, partitions, fireplaces, chimneys, as well as other structures with brick or concrete block.
