Concrete is a composite material commonly used for construction work consists of 3 main components: cement, composite materials (such as stone, sand or gravel) and water, there may be additional chemicals added to it for another property. Where the water and cement to chemical reactions in the style known as Hai de migration. By cement and other materials will begin with capture and clotting, which in this State is known as concrete. It also strengthened after curing, curing estimated 28 days after a strong start, fixed
.
Concrete is widely used in many types of construction, including the building of roads and bridges, dam construction, the monument, which is visible in General
.The main features of concrete compression strength is high. While you can get the lowest tensile strength (about 10% of pressure), to make the concrete tensile strength can be complementary to other materials will be added to the concrete, it is called. The reinforced concrete or referred to (by reinforced with steel) These materials will help you get an internal tensile strength of concrete, structural building mainly used concrete reinforced concrete instead of naked
.
In addition, the construction method is also known as prestressed concrete by placing a force into the concrete casting success at casting factory when applied. This will make the concrete more weight can be obtained by using the top level and elevated bridge prestressed concrete.
