Abstract:
A test program was carried out to develop information about the mechanical properties of high-performance concrete. High-performance concretes with 56-day compressive strengths of 65 to 120 MPa (with or without silica fume) were studied. Results and discussions are presented regarding com-pressive 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 ACI 318-M equation for the modulus of elasticity of normal-weight high-performance concrete is recommended. 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 supple-mentary cementitious materials and with 28-day compressive strengths up to 120 MPa.
