The purpose of this study was to examine the mechanical and durability properties of high-volume fly ash concretes for structural applications. Four concrete mixtures were prepared with the amount of fly ash, from Italian source, varying from 0 to 50 percent by weight of total cementitious materials. A large number of concrete specimens were cast and tested to determine the compressive, flexural, and splitting tensile strengths, modulus of elasticity, fracture parameters, concrete-steel bond properties, drying shrinkage, and durability properties. The results of this study showed that high-volume fly ash concrete has considerable potential in a wide variety of structural applications.
