Reading
Ex- 1: Read the text and discuss it;
Materials that are used for structural purposes should meet several requirements. In most cases it is important that they should be hard, durable, fire-resistant and easily fastened together. The most commonly used materials are timber, stone, concrete, steel, brick, light materials, glass, plastics. They differ in hardness, durability and fire-resistance.
All building materials are divided into three main groups:
Main building materials such as stones and artificial stones timber and metals;
Binding materials such as lime, gypsum and cement.
Secondary or auxiliary materials which are used for the interior parts and buildings.
We use many buildings materials for bearing structures. Binding materials are used for making artificial stone and for joining different planes. For the interior finish of the building we use secondary materials. If the materials do not require any changes in their chemical structures they are known as natural building materials. They are stone, clay, sand, lime and timber. Cement, clay products and concrete are examples of artificial building materials. Now building materials are changed into units of assembly, prefabricated or precast construction members.
