Concrete with a compressive strength approaching 20,000 psi (138 MPa) is now available commercially. Researchers predict that strengths of 25,000 (173 MPa) and even 30,000 psi (207 MPa) can eventually be achieved without the use of exotic materials, special processing under high temperatures, or special atmospheres and high casting pressures. As concrete strengths continue to increase, the significance of good quality control procedures becomes increasingly more important and is a critical factor influencing the overall success of a project.
