Brick

A brick is a block of ceramic material used in masonry construction, usually laid using mortar. Bricks are used in construction for centuries, they’re used for used for building and pavement and they are also used in the metallurgy and glass industries for lining furnaces. There are basically fives types of brick: common brick, face brick, refractory bricks, calcium silicate bricks and glazed brick. Common brick is the everyday building brick and it’s not made of special materials. Face brick is applied on top of common backup brick. Refractory bricks are used in various types of furnaces, kilns, and fireplaces. Calcium silicate brick are made in areas where clay is not readily available. Glazed brick are made primarily for walls in buildings such as dairies, hospitals, and laboratories, where easy cleaning is necessary. Bricklaying is a trade that specializes in building and repairing walls, floors, partitions, fireplaces, chimneys, as well as other structures with brick or concrete block. Bricklayers are responsible for a variety of work. Typically it involves hands on bricklaying like measuring the work area following the architect's plans, mixing mortar by hand or with a mechanical mixer, laying the bricks and applying the mortar, shaping and trimming bricks using bricklaying tools and checking that the brick wall is straight.

· It’s very useful because a bricklayer may use their skills for residential or large commercial development projects. · Bricklayers may also refurbish brickwork on restoration projects functional. They are in high demand due to urban revitalization programs, building programs and large development projects being built throughout the UK. So, it’s a good trade.

· It’s a meticulous work, because there are many chemical and mineral pr ocesses involved. · Some uses of bricks are common in areas of northern England and som e outskirts of England. So, there are not that uses in Latin American countries.

1. Brick **__compares__** favorably with stone as a structural material for its fire-and-weather resisting qualities and for the ease of production, transportation and laying. 2. **__But__** shapes, along with the techniques of bricklaying, have varied widely throughout history. 1. The size of bricks **__is__** limited by the need for efficient drying, firing, and handling. 2. **__Its fire-and-weather resisting qualities__** and for the ease of production, transportation, and laying. 1. Special shapes can be produced by molding to meet particular structural or expressive requirements (**__for example, wedge-shaped bricks are sometimes employed in arch construction and bricks with rounded faces in columns__**). 1. Brick which has been used since the 4th millennium BC. (Are you sure, what is the cause and the effect in this sentence?) 1. **__The commonest ancient Roman__** bricks were cut into triangles and laid with the base out and the apex set into a concrete filling that provided additional strength. 2. Brick which has been used since **__the 4th millennium BC__**, was the chief building material in the ancient Near East. The versatility of the medium was expanded in ancient Rome by improvements in the manufacture of both brick and mortar and by new techniques of laying and bonding. Employed throughout the **__Middle Ages__**, brick grained greater popularity from the **__16th__**. Century on, particularly in northern Europe. It is widely used in **__the 20th Century__**, often for nonbearing walls in steel frame constructions.
