Concrete


 * CONCRETE **

Concrete is a very common material in the constructions for its resistance, its durability and because it can mould to produce great variety of structural forms. Its components are:water, cement and small stones. Concrete is strong for compression but weak in tension.

It was used in ancient Egypt and developed by the Romans in the architecture and structures to cover large areas. In 1849 Joseph Monier invented the reinforced concrete, where the structures are reinforced with the combination of concrete with other materials like steel.

In the 20th century, three types of concretes are developed that determined an impact on the architecture: concrete-shell construction,precast-concrete construction, and prestressed concrete.




 * Difference and similarities between tiltwall construction, tilt-up panel construction and pre-cast concrete construction**

Tilt-up and tiltwall are assembled and poured directly at the job. “Tilt-up affords more flexibility; it is the method of choice in locations where the weather allows it. Precast concrete is a suitable choice in circumstances where environmental factors and the construction schedule preclude tiltwall as a viable option”. And precast concrete not found in tilt-up construction because the panels must be transported.
