3. Read the text again and find the main idea of each paragraph.

4. Reading far specific information. Read the text and answer the following questions to the text:

• Why is it preferable to elevate all raw materials into overhead storage bins?

• Is it axiomatic now that materials can be handled more cheaply with machinery than with manpower?

* Why should be the following general aspects kept in mind when designing a plant?

* Why is a great number of plants producing recast reinforced-concrete elements now in operation in our country and abroad?

 

With a great number of plants producing recast reinforced-concrete elements in our country and abroad it is a rapid growth of recast-concrete products. Particularly they are wall panels, slabs, beams to serve a multitude of building needs. This industry has a task to maintain and improve the quality of the products. A lot of excellent work has already been done to raise the standards of this industry to their present, level.

First of all, a well-designed plant must be established in a given area. A careful appraisal of the potential requirements provides valuable information for determining the size of the plant which should be built. A number of economic considerations deserve a particular attention. The following general aspects should be kept in mind when designing a plant. The plant floor level should be not 6 inches above the general grade of the yard to assure. In addition, concrete yard runways should be slightly above the level of the surrounding yard so that they will remain free of pebbles and other obstructions that might interfere with the operation of trucks or other equipment. The yard should slope away from the main building in all directions if possible. Adequate space should be allowed at sides and in front of machines and casting beds.

Then, a well-designed plant must have sufficient capacity for the normal output plus reasonable margin for a possible increased.

The design should specifically and carefully antic-creased production without disrupting the original lay-out. Regardless of the general lay -out of the plant, aggregates and cement should be stored as close to the mixers as possible. Machinery and equipment designers have made important contributions by creating better machines and tools for the industry. It is axiomatic now that materials can be handled more cheaply with machinery than with manpower. All raw materials are elevated into overhead storage bins. The materials may move by gravity from the bins to the mixers and molding machinery without re-elevating. With such an arrangement the mixers are located on a separate floor level directly above the molding machinery. In large plants producing precast-concrete elements the moulded units are delivered from the moulding machinery to high-pressure steam curing autoclaves for further treatment:

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

* At present in our country there are but a small number of plants producing precast elements.

* Ordinary brick is an artificial stone made of clay by moulding and burning.

* Hi is recommended to store aggregates and cement as close to the mixer as possible.

* When designing a plant it is necessary to anticipate the future installation of additional equipment.

* It is not economic to elevate all raw materials into storage bins over the mixers.

* The yard should slope to the main building of the plant from all directions.

* Materials can not be handled more cheaply with machinery than with manpower.

.* Particularly they are wall panels, slabs, beams to serve a multitude of building needs.

* A well-designed plant must be established in a given area.

* The plant floor level should be not 10 inches above the general grade of the yard to assure.
