Abstract:
Material Service Corporation has developed and commercially marketed high-strength silica fume concrete (HSSFC) in the Chicago area. This concrete, with design strengths ranging from 10,000 to 14,000 psi (70 to 97 MPa), has been supplied successfully to over a dozen high-rise projects. Currently, preparations are being made to commercially market concrete with a design strength of 16,000 psi (110 MPa). Continuing optimization of the mix design has resulted in full-scale test placements of concretes with compressive strengths surpassing 20,000 psi (140 MPa).
