Abstract:
Ultra high-strength concrete is now available to the commercial construction market at field placeable slumps in the compression range of 10,000 to 18,000 psi (69 to 124 MPa). Laboratory studies and field test programs have been conducted to evaluate a new silica fume-type admixture’s capability to produce state-of-the-art high-quality concrete over a range of applications. Over 8000 yd3 (6120 m3) of high-strength concrete have been placed in industrial applications during the last four years.
