Some of the most important building

Some of the most important building materials are : timber brink stone concrete metal plastics and glass.
Timber is provided by different kinds of tress. timbers used for building purposes are divided into two groups called softwoods and hardwoods. timber is at present not so mach used in building construction as in railway engineering in mining and in the chemical industry where it provides a number of valuable materials.
however, timber is still employed as a building material in the form of boards. for the interior of buildings plywood and veneer serve a number of purposes.
A briсk is best described as a building unit. it may be made of clay by moulding and baking in kilns, of concrete, of mortar or composition of sawdust and other materials. in shape it is a rec: angular solid and its weight is from 1|6 to 9 Ib/
There exists variety of bricks for different purposes: ordinary hollow or porous lightweight multicolor bricks for decorative purpoman pular for many hundreds of years. The hand of the average man is large enough to take a brink and he is able to handle more thar 500 bricks in an eidht - hour working day. It is necessary therefore for the "would be" bricklayer to practise handling a brick until he dan control it with complete mastery and until he a able to place in into any desired position.
The brick may be securely handled by placing the hand ower the surfaсe of the upper part of a brick and by placing the hand over the surfase of the upper part of a brick with " the joints of the fingers on the opposite fage. It is better to protect the thumb and the fingers with leather pads, which also prevent the skin from rough bricks.
Sometimes natural stones such as marble, granite, basalt, limestone and sandstone are used for the construction of dams and foundations. Marble granite and sandstone are widely used for decorative purposes as well, especially with the puplic buildings.
Natural stone is used for foundations and for the construction of dams. The main varieties of building stone are basalt, granite, marble, sandstone and limestone.
Metals: aluminium, principally in the form of various alloys, is highly valued for its durability and especially for its light weight, white brass is frequently used for decorative purposes in facing.
Steel finds its use in corrugated sheets for girders, frames, ect. Various shapes are employed in construction.Plastics are artificial materials used in construction work/ for a vast number of purposes. nowadays plastics which are artificail materials, can be applied to almost every branch of building. from the laying of foundation to the final coat of paint. synthetic resins are the main raw material for plastics. plastics have some good advantages as they are lighter than metals, not subject to corrosion, and they can be easier machined. besides, thee are inflammable, they can take any color and pattern, and they are good electrical insulators. more over, they possess a high resistance to chemical action.
a lot of decorative plastics, now available , have brought about a revolution in interior and exterior design. but plastics are used now not only for decoration. these materials are sufficiently rigid to stand on their own without any support. they can be worked with ordinary builders tools.
laminate is a strong materials manufactured from many layers of paper or textile impregnated with thermosetting resins. this sandwich is then pressed and subjected to heat. laminate has been developed for both inside and outside use. it resists severe weather conditions for more than ten years without serious deformations a structural materials it is recommended for exterior work. being used for surfacing, laminate gives the tough surface.
foamed glass is a high - porosity heat insulating material, available in block made of exterior wall panels, and in industrial construction.
foamed glass has a high mechanical strenght, is distinguished by moisture, vapour and gas impermeability. it is non - inflammable, offers resistance to frost, possesses a hight sound adsorption, and it is easily sewn and nailed.
structural foamed glass blocks designed to fill ceitlings, and for making partitions in buildings and rooms, to ensure heat and sound insulation.
for insulation mineral wool or cinder wool is often resorted to.

Деякі з найбільш важливих будівельних матеріалів: Пиломатеріали межі каменю бетонні металеві пластмас і скла. Пиломатеріали забезпечує різні види Тресс. Пиломатеріали, які використовуються для створення цілей діляться на дві групи, які називають softwoods і листяних порід. Деревина є в даний час не так Маха застосовуються при будівництві, будівництво, як і залізничних інженерії у гірничодобувній промисловості та у хімічній промисловості, де вона забезпечує ряд цінні матеріали. Однак, деревини і раніше використовується як будівельний матеріал, у вигляді дошки. для внутрішньої частини будівель фанери й шпони служать кількість цілей.У briсk є найкраще можна описати як єдине ціле будівлі. Це може бути зроблено з глини лиття і випічки у печах, бетону з розчину або склад тирси та інших матеріалів. у формі це rec: твердого кутового і його вага – від 1|6 до 9 Ib /Існуюча в ньому різноманітність цегли для різних цілей: звичайні пустотіла або пористого легкий багатобарвної цеглу для декоративних purpoman pular протягом багатьох сотень років. Рука середня людина достатньо великий, щоб взяти на межі і він здатний обробляти більше Тар 500 цеглини у eidht - годинний робочий день. Це необхідно, тому для муляр "б", щоб практикувати обробки цегла, поки він dan контролювати його з повним майстерності і поки він може помістити в в будь-якої бажаної позиції.The brick may be securely handled by placing the hand ower the surfaсe of the upper part of a brick and by placing the hand over the surfase of the upper part of a brick with " the joints of the fingers on the opposite fage.

Одні з найбільш важливих будівельних матеріалів: дерево межі камінь конкретні металевих пластмаси та скла. Кратність бруса забезпечується різних видів Зелених Свят масового нищення дерев. брусами використовується для будівельних цілей поділяються на дві групи під назвою хвойних порід за розміром і пошкодженням листвяних порід.Дерево - зараз не так мась використовується в будівельних конструкцій як в залізнична техніка в гірничо-хімічної промисловості, де вона забезпечує ряд цінних матеріалів. Однак
Петре, деревину, як і раніше працюють як будівельний матеріал, у вигляді плит. для інтер'єру будинків фанери й шпона відбувати номер цілей.
A briсk найкраще описати як будівництво блоку.
