It combines the compressive power of concrete with the tensile energy of steel reinforcement, causing a cloth which can withstand high hundreds and forces.

The power of concrete is measured in pounds for every square inch or kilograms for every sq. centimetre of drive necessary to crush a sample of a given age or hardness. Concrete’s power is impacted by environmental factors, especially temperature and dampness. Whether it is allowed to dry prematurely, it may encounter unequal tensile stresses that within an imperfectly hardened condition can't be resisted. In the method generally known as curing, the concrete is kept moist for a long time immediately after pouring to gradual the shrinkage that occurs because it hardens.
