IV. Read and translate the text brick

Brick was the first artificial building material made by man of clay and sand. There are practical and economic reasons why the use of brick has survived. Brick is reasonably priced, standardized product, durable, with good insulating properties, satisfactory porosity and weather-resistant.

Historically the use of brick has been influenced by the availability of raw materials. The main material clay can be obtained practically everywhere. Egypt and Mesopotamia have some of the earliest examples of brick -making. The Romans were quick to see its potential and organized production where they found the raw materials. In England the art of brick-making came and went with the Romans. But it revived in the Middle Ages and since then there has been the development of mass-production techniques and transport systems to deliver the products. In Russia bricks have been used in construction for centuries.

The basic principles of brick-making have never changed. This process was rather simple. Nowadays there are also four stages in the manufacture of bricks: 1) mixing the raw material, 2) forming 3) drying and 4) burning.

There are different kinds of bricks: facing, common, engineering, hollow and porous: reinforced and refractory. Facing bricks have a pleasant appearance. Common bricks are cheap. Engineering bricks have excellent resistance to impact, corrosion and wear. Hollow and porous bricks are lightweight and more economical than common ones.

Bricks are of different size, colour and texture. The principal structural defect of brick is its porosity.

Bricks are widely used in construction:

1) for bearing elements, for example, walls and foundations

2) for producing aggregates

3) for decoration.

4) reinforced and refractory bricks are used in the metallurgy and glass industries for lining furnaces.

Brick structures require almost no maintenance. They are characterized by high durability and can last for hundreds of years.
