ENGINEERING PROPERTIES OF COMMERCIALLY AVAILABLE HIGH-STRENGTH CONCRETES (INCLUDING THREE-YEAR DATA)

This report summarizes information from a three-year study of engineering properties of high-strength concrete. Six concretes in the range of 10,000 to 20,000 psi (69 to 138 MPa) were studied. Water-to-cement ratios ranged from 0.26 to 0.43; water-to-cementitious material ratios ranged from 0.22 to 0.32. The concretes containing either no mineral admixtures, silica fume only, or both fly ash and silica fume were delivered by a ready-mix supplier for laboratory tests. These tests included temperature rise of large cube specimens; compressive strength of cylinders, cores, and insulated specimens; static modulus of elasticity; tensile strength; modulus of rupture; thermal expansion; drying shrinkage; freezing and thawing durability; relative humidity; specific heat; thermal conductivity; and water absorption. Specimens were also prepared for testing for creep, drying shrinkage, rapid chloride permeability, resistivity, corrosion rate, and petrographic analysis.
