Importance of Precast Concrete & Its Requirement In UAE!
Precast concrete is used by a variety of designers. Post-tensioning is an alternative to make concrete stronger by pre-stressing it. Steel used for pre-tensioning, like wires, strands or bars, are used for the purpose of adding compressive forces to concrete. Precast works are strained prior to the time that concrete is being poured. The force that is strained will be transferred onto the concrete by the bond. In contrast to pre-tensioning, post-tensioning is possible on the spot of work in situ applications. Casting precast concrete parts is accomplished by using steel reinforcing wires that are placed in a way to protect them from bonding to concrete. This method allows designers to improve the efficiency of the materials by making more compact concrete components. The components utilized in post-tensioning concrete components include high strength steel strands and bars. Horizontal applications, such as beam foundations, slabs, bridges, and beams usually make use of s...
