Concrete has its flaws. The most obvious flaw is its lack of strength when it comes to tension.
Concrete is able to withstand massive amounts of compressive stress and strain, when you do attempt to separate it from the rest to break it down, it will give way effortlessly. The weakness of concrete is its fragility. Concrete lacks the ductility and stretch that concrete needs. It can result in cracks and crevices.
What exactly is prestressed cement, and how can it be used?
Because concrete is not without its share of weaknesses, prestressed concrete tackles its problems in all aspects to offer a superior and stronger type of concrete which is capable of enduring an extreme amount of stress without cracking. Concrete that is pretressed is compressed using rods and beams of steel.
The basics of making prestressed concrete:
When it comes to the process of concrete making, a concrete frame is created by the prestressed service the beam of concrete. The frame will hold the tension of the steel as the concrete is poured and then cured. cielkbtm41.
