Abstract:
Concrete is now available commercially having a compressive strength approaching 20,000 psi (138 MPa). Researchers predict that even higher strengths 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. An interlaboratory test program was conducted to determine the effect of selected variables on the measured compressive strength of high-strength concrete and conclusions and recommendations are presented.
