TENSILE PROPERTIES OF HIGH-PERFORMANCE CONCRETE

Properties of high-strength concrete under uniaxial states of stress are studied. Main emphasis was given to tensile, compressive and fracture properties of concrete with compressive strengths ranging from 6000 to 12,000 PSI. Complete stress-deformation curves under uniaxial tension were obtained using a close-loop servo-hydraulic testing system. Important mechanical and fracture properties such as moduli of elasticity, fracture energy, Gf, and the critical crack tip opening displacements, Wc are evaluated from the experimental results. Fracture energies were evaluated from the descending branch of stress-crack separation curves using the direct tension test results. For the range of high-strength concretes studied, experimental results indicate that the relationship between tensile and compressive strengths are different from those of normal strength concretes.
