To understand and document the mechanical properties of high-performance concrete, a test program was initiated. High-performance concretes with 56-day compressive strengths of 65 to 120 MPa were examined. Findings and discussions are presented regarding compressive strength gain with time, effect of type of cement, effect of drying, specimen size effect, static modulus of elasticity, Poisson's ratio, tensile splitting strength, and modulus of rupture. A modification of the American Concrete Institute (ACI) 318-M equation for the modulus of elasticity of normal-weight high-performance concrete is proposed. The validity of equations recommended by ACI 363R for estimating tensile splitting strength and modulus of rupture can be extended for high-performance concretes with or without supplementary cementitious materials and with 28-day compressive strengths up to 120 MPa.
