Various materials are used as a solution for fastening. It was so a long ago. Sometimes in Mesopotamia (modern Iraq) masters applied resin substance — bitumen. Egyptians used plaster (sulfate of calcium). Greeks and Romans originally worked with oxide calcium. But the limy solution was easily washed away by a rain. Subsequently Greeks and Romans took more durable cement mortal on arms — a mix to exhaust, sand and volcanic ashes. Later Romans began to add to it gravel for reception of concrete. Greeks continued building of integral blocks of a stone or marble. One more major landmark became manufacturing bricks in the furnace for roasting at high temperatures. So it was received stronger and more durable material in comparison with samanom. But Romans used only thin layers of these materials for lacing concrete designs. Besides dwellings, builders could erect majestic palaces, temples and monuments. They also decorated with their decorative stone lying.

Many things are made by metal tools. Metal tools allow cutting, squaring and polishing a stone. Metal tools such as an axe, а saw, builders used many years ago. Also they had an opportunity to use available materials more widely. Now they could cut the big trees and split them and bars.

5. Reading for general understanding. Skim read the text. Think
of a good title for it. Compare it with other students' titles.

Many new materials are familiar to us over centuries. We are pretty well acquainted with the advantages and disadvantages of wood. We know that glass is transparent, but in some ways it is rather brittle. Glass has the advantages of cheapness, rigidity and chemical inertness. We are aware that most metals can stand severe handling, but some of them rust.

But such materials as plastic materials are not found in nature. Some years ago plastics were little more than laboratory curiosities! Today plastics are conceived in the laboratory of the chemical plant. But plastic is formed by extrusion or injection molding under very high pressure. It can be molded into any desired shape. Organic plastics are divided into two general groups: thermosetting and thermoplastic. The thermosetting group becomes rigid through a chemical change that occurs when heat is applied. These plastics cannot be remolded. The thermoplastic group remains soft at high temperatures and must be cooled before becoming rigid. This group is not used generally as a structural material.

Plastics are rapidly becoming important construction materials because of their great variety, strength, durability and lightness. The high strength to weight ratio of some plastics offers big field in the coming age of space travels and rockets. Plastics are light. The same benefits of light weight coupled with good strength and absence of corrosion offer tremendous potential as alternatives to traditional building materials. A given volume of polythene weights less than one-eighth of an equal volume of iron and less then half of the same volume of aluminum. The following characteristics of plastics are usually shared by all plastics: lightweight, corrosion resistance, electrical and thermal insulation, ease of fabrication, transparency in some materially ease of coloring and economy of production.

These characteristics of plastics explain their increasing acceptance by industries. The development of plastic has been so rapid. Since World War 11 there have been rapid developments in the manufacture of blown thermoplastic bottles made of polyethylene, polypropylene, polyvinyl chloride, or some other plastics. Plastic bottles are much lighter and less fragile than glass bottles. We can hardly name a branch of industry where plastics are not applied. Plastics have been already used in the industry: from rockets and electronics to toys and house ware. Plastic products offer many advantages over the materials they replace, such as ease of handling, lower maintenance costs and rapidity of assembly. The insulation and dielectric properties of plastics led to their early use in the electrical engineering industry, which was followed by special application in mechanical engineering. Automobile, aircraft and shipbuilding industries have also made use of advantages offered by plastics.

Using of plastics as materials for a construction in the form of sheets, rods or tubes is substituting the conventional metals. Plastics offer a lot of properties for the designs. Plastics have now been developed to such an extent that they can be applied to almost every branch of building, tram the laying of foundations to the final coat of paint.

PLASTICS

Warming - up

1. Discuss the following:

• What do you know about plastics?

• What plastic products are you familiar with?

2. Try to guess the meaning of the following words. Use the dictionary if you need:

• plastic

• resin

• organic

• volume of polythene

• revolution in interior and exterior design

3. Read the text and find new words from the text.

4. Reading for general understanding. Skim read the text. Think of a good title for it. Compare it with other students' titles.

One of new synthetic materials used widely is plastic. Although the first plastic, celluloid was introduced 100 years ago. Some types of plastics are very tough, e.g., nylon. Others may be relatively brittle, as polystyrene. Plastic is not as strong as iron or steel or concrete when it comes to supporting great weights. Plastics do not rust and therefore require no protective layer, such as paint, which can subsequently peel off. They can be colored and such .color is part of the material. Some types will withstand higher temperatures than others and the ceiling temperature is constantly being raised as new varieties appear. Plastics have found wide application both in everyday life and in industry.

It is a decorative plastic — laminate. It consists of paper filler impregnated with thermosetting resins, on top of which is laid similarly impregnated paper. The paper itself is topped with a melamine resin treated skin which gives a tough surface. This sandwich being then pressed and subjected to heat. A laminate has been developed which is suitable for both inside and outside use. It is used by an architect and a builder in interior and exterior design. A Laminate can be worked by all the methods commonly employed by a builder. A Laminate has some weathering properties. There were many disadvantages in the development of decorative laminates before they could be put on the market. Its chief advantage is that it needs no maintenance other than an occasional wipe down with a damp cloth. Another important property is that curved surfaces can be introduced and sharp comers eliminated in areas where hygiene is an essential consideration.

8. Reading for specific information. Read the text, choose a right word.

9. Read the paragraphs about Reinforced and Foamed Plastics and answer the following questions:

• What is added to create a reinforced plastic?

• What are foamed plastics?

Reinforced Plastics. In order to improve the (mechanical, plastic) properties of resin, glass fibers are often added to create a reinforced (plastic, water). Glass fabrics offer great potential for structural use. Since the (glass, iron) fibers have tensile strengths up to 600.000 (42.000 kg/sq cm)? their addition to a resin results in a composite (material, work) with an ultimate strength up to 250.000 (17.500 kg/sq cm), although lower strength combinations are normally used as structural (panels, boxes) as structural shapes such as I-beams and as bodies for ships and trailers. Ал experimental (house, work) built in Disneyland in 1956 has a reinforced plastic shell.

Foamed Plastics. Foamed plastics, such as urethane and polystyrene, have very low compressive and tensile (strength, glass) and puncture easily. They can be used between two layers of a hard surface material such as a metal to create a laminated (sandwich, ship) panel with high stiffness. Such panels are used as floors, partitions and exterior walls in (buildings, garages).

10. Read the following statements and say whether they are true of false. Correct the false statements:

• Plastic like heat.

• Plastic can not part of the material.

• Plastic is not applied in industry.

• The use of plastic in the form of robs or tubes are substituting the conventional metals.

• There was a drop in power consumption of between 10 and 20 percent.

• It is a decorative plastic — laminate.

• It is not used .by an architect and a builder in ulterior and exterior design.

• Some types of plastics are very tensile.

• Color is part of the material.

• There were many advantages in the development of decorative laminates.
