Mixing the components in the thoroughly managed procedure results in a paste that coats and bonds the combination particles. The hardened concrete has interconnected air voids totaling somewhere around fifteen to 25 percent.

It combines the compressive toughness of concrete with the tensile strength of steel reinforcement, leading to a fabric which will withstand substantial loads and forces.

far better distributing the stresses within the construction for making best use in the reinforcement. For instance, a horizontal beam has a tendency to sag. Prestressed reinforcement along here The underside in the beam counteracts this.
