Concrete



 ** The concrete is a material made from a mix of cement and water, with sand and stones. When is solid has strength and compression capacity but is very weak if you apply tension on it. This material is use to make a great variety of structural elements, because it could be poured and transform while still liquid and can be fuse with other materials. (That’s why it’s an economical substitute for traditional material)
 * Concrete

The ancient Egypt and Romans did employ the concrete but the Romans were the ones that developed the concrete, this aloud a great expansion in architectural methods and the creations of domes, vault, bridges and water-proofing systems. The manufacture of concrete decline on the middle age and regain importance with the invention of reinforced concrete.

The reinforce concrete was invented on 1849 by Joseph Monier. Was developed to add the tensile strength of steel to the compressive strength of mass concrete, it was promoted for the use in railways ties, pipes, floors and bridges. In combination with steel, this combination is more versatile it use also in structure like columns and beams.

Then in 20th Century the concrete has a huge impact on the architecture. With the concrete- shell constructions, precast-concrete construction and prestressed concrete.
