Concrete

Concrete is a material made with cement, water and small stones, it cost is low and its weight is medium. Concrete is very strong in compression, it is waterproof, fireproof and it can be made of any shape. By the other hand it is weak to tension and it can crack easily with temperatures changes. As many people may not know, concrete is used from the ancient Egypt to the Roman Empire, but it wasn’t until 1849 when the concrete was invented as we know it. This new concrete is the “reinforced concrete”, developed to add the tensile strength of steel to the compressive strength of mass concrete.

Concrete has a radical impact on architecture after its many years of development. Also it is used in different ways for creating singular spaces with many advantages, for example, the concrete shell permits the construction of domes, the precast concrete decrease the time and cost of the construction and the prestressed concrete is used for carrying great loads. Concrete is a manufactured mixture of cement and water, with aggregates of sand and stones  Reinforced concrete

** Differences between **** tiltwall construction, tilt-up panel construction and pre-cast concrete construction ** T ilt-up and tiltwall are two terms used to describe the same process. It consist in modular concrete elements (i.e. walls, columns, structural supports, etc.), formed on a concrete slab; usually the building floor. By the other hand, precast concrete process is similar but in this case, the concrete is cast in a reusable mould or which is then cured in a controlled environment, transported to the construction site and lifted into place.
