** Stones: **

Stones are rock formations used by the men for building. They are the product of aggregate of minerals, mineral alloys and water as well as changes in pressure and temperature. Stones have a big importance into the architectural and construction world. They are used in many applications like decoration and in at construction as concrete aggregate. The reason because stones are pretty used is that    they have great durability; they can be adapted to sculptural treatment and can be use in their natural form given by their different colors and textures. Between many disadvantages we can say that stones are difficult to transport and cut, especially because they are very strong.

Bricks are made from  [|clay]  ,   [|shale]  , soft slate,   [|calcium silicate]  , concrete, or shaped from quarried stone, but clay is considered the most common material ==== Bricks are used in  [|masonry]    construction, for building,   [|pavement]  , as a decorative surface and in the   [|metallurgy]    ==== ==== and  [|glass]    industries for lining   [|furnaces]  . ==== ** ** There are many types of brick **. Some are    different in formation and composition while     others vary according to their use

**<span style="font-size: 14.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Arial; color: black; mso-ansi-language: EN-US;">Iron ** ** : Iron is able to mold in any shape and is strong in compression. Is weaker than steel in tension and breaks without warning. Iron has frequent use at the construction of arch bridges, cannons and historic domes.

<span style="font-size: 10.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Arial; mso-ansi-language: EN-US;"> Steel is one of the strongest materials used in construction, due to its strong in tension and compression. However loses strength in extremely high temperatures <span style="font-size: 14.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Tahoma; color: green; mso-ansi-language: EN-US;">

**Concrete:** Concrete is a manufactured mixture of cement and water, with aggregates of sand and stones, which hardens rapidly by chemical combination to a stonelike, water-and-fire-resisting solid of great compressive but low tensile strength. <span style="font-size: 10.0pt; font-family: "Comic Sans MS"; mso-ansi-language: EN-US; mso-bidi-font-weight: bold;"> The importance of concrete in construction is its ability to be mold in different ways and sizes, it is a very strong material, Concrete is resistant to hight tempetatures without cracking and it can be mixed to other materials without show any physic or chemical change. Another important advantage of concrete as material construction is that is easy to produce  it and has low cost. <span style="font-size: 10.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Arial; mso-ansi-language: EN-US;"> <span style="font-size: 10.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Arial; mso-ansi-language: EN-US;">

**Wood:** Wood is an organic material very useful at construction by its physic and mechanic properties. It is use for boats, houses construction but also on sculpture, musical instruments manufacture and as raw material on the industry of paper. <span style="font-size: 10.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Arial; mso-ansi-language: EN-US;"> <span style="font-size: 10.0pt; font-family: "Comic Sans MS"; mso-bidi-font-family: Arial; mso-ansi-language: EN-US;"> Wood is more resistant than steel or concrete in high temperatures because keeps its structure and load capacity. As concrete is very use at construction by its low cost.

**Glass:** Glass is an inorganic product of fusion which has been cooled to a rigid condition without crystallizing. Many glasses contain [|silica]     as their main component Glass plays an essential role in science and industry. The optical and physical properties of glass make it suitable for applications such as     [|flat glass] ,  [|container glass]  ,      [|optics]      and      [|optoelectronics]      material,      [|laboratory equipment]  , thermal insulator (  [|glass wool]  ), reinforcement fiber (  [|glass-reinforced plastic]  ,  [|glass fiber reinforced concrete]  ), and      [|art].
