Concrete

 **Concrete** //Concrete like construction material//

The **Concrete** is a cheaper material, result of the mixture of cement, water and small stones. This is a strong material in compression but very weak in tension. Also the concrete can break with change of temperatures. It's very importat that the concrete can be in fusion with some kind of materials and can be an economical substitute of others.

The concrete was exist since very years. This was employed in ancient Egypt and developed by the Romans. One example of a concrete construction is the Pantheon in Roma, Italy. After 1860 was invented the reinforced concrete and was developed to add the tensile strength of steel to the compressive strength of mass concrete

The **Reinforced Concrete** is the kind of concrete developed to gave it the tensile strength of iron because, as I sayd before, the concrete is very strong in compression but weak in tension, so the Reinforced Concrete is a well material in tension and in compression.



In the 20th had three radical effects to architecture: concrete-shell construction, precast-concrete construction and prestressed concrete.
