Without concrete products during the construction of realistic enough. jbi incredibly much: road plates, elements basements, pillars, etc. All products are reinforced in its structure two main components: an iron rebar and mixture. Concrete is classified according to strength: tensile strength along the axis, stretching during bending, compression. Grades of concrete differ in average density, water resistance and cold resistance. Concrete, in principle, is a mix of cement and water. The reaction between these two components and are connected to the whole grain mass.
Known two types of iron fittings: the working and assembly. Working valves located at the bottom reinforced concrete construction and is designed for bending and assembly used to manufacture the bulk of the skeleton. Each product has its own recipe of concrete products manufacturing and the percentage mix of components. Production method varies depending on the destination of each product. If the need to work on a bend, the armature is poured into a stretched form, and concrete pre-straining. This gives the design strength. Similar designs found a use for its floor slab and bridges.
That's why every concrete products has its own secrets of creation and operation. Each design has a scheme in which is mounting. Deviation from the norms usually entails very serious consequences. Reinforced concrete structures are extremely durable and reliable, but concrete is prone to fracture. It occurs when abnormal conditions of storage, when there is mold and fungus. In this connection is not recommended to keep the concrete products in areas with high humidity. In addition, the reinforced concrete rather fragile and requires the creation of special conditions for transportation.
