Stone:  It is a natural and solid element conforms by an aggregate of minerals. Since the Prehistory it was used for construction because of its advantages like : __Its durability: __  The stone guarantees centuries of using life. A big prove of this can be appreciated in ancient constructions like Stonehenge and Egyptian Pyramids . __Its resistance: __  This material provides resistance to some unexpected situations like earthquakes, weather changes and case of fire . __Its adaptability: __ The stone give us the opportunity to create different structures like arches, columns, beams and bridges . __ Its origin: __ It doesn’t need especial treatments because it is used just like we find it in nature, an important advantage because it provides a lot of arrangement.

Brick:  A brick is a small block made of a mixture of clay and sand that is mainly used for make walls in constructions. The bricks work like beams to support walls, and also give the opportunity to decorate them. Nowadays we can see many buildings that show a façade decorated with bricks, giving a sensation of an old construction that also seems to be comfortable and pleasant . <span style="font-family: 'Tahoma','sans-serif'; font-size: 110%; line-height: 115%;">One advantage of bricks could be that they not only can be used for construction, but also for decoration because of its appearance that adds dimension, texture and integrity, and one disadvantage is that they are strongly resistant in compression but in tension are just so fragile and also bring a lot of weight to the structure.

It is a strong, heavy, hard and gray metal with a strongly attraction to magnets. It is used to make many things for construction like structures, gates, windows and so on. This metal also can be combined with carbon to create the steel, an even harder metal with more advantages. The steel have the property of be strength, resistant in compression and in tension and is used to reinforce the structures and also to make machines, cars, tools, knives and many other things <span style="font-family: 'Tahoma','sans-serif'; font-size: 10pt; line-height: 115%;">.

<span style="color: #0070c0; font-family: 'Tahoma','sans-serif'; font-size: 121%; line-height: 115%;">Concrete: <span style="font-family: 'Tahoma','sans-serif'; font-size: 11pt; line-height: 115%;"> It is a construction material made of cement and few quantities of other materials such as granite, water sand and chemical mixtures. This material is used to make structures, roads, bridges, bricks, fences and other elements used for construction. Some properties of the concrete are that it is resistant in compression but fragile in tension and it doesn’t deform so much with thermal variations <span style="font-family: 'Tahoma','sans-serif'; font-size: 10pt; line-height: 115%;">. <span style="font-family: 'Tahoma','sans-serif'; font-size: 110%; line-height: 115%;">The concrete is considered the most durable, sustainable and safest building material, because it offers more resistant in case of fire and guarantee an extremely long service life. Also, one advantage of using this material is that it doesn’t coast so much.
