This report presents the findings of an extensive scientific and engineering investigation of the properties of high-volume fly ash (HVFA) concretes prepared from a broad range of portland cement and fly ash materials from sources throughout the United States. The purpose of the project was to support commercialization of HVFA concretes, and hence enhance the beneficial use of fly ash in value-added products. A total of sixteen HVFA concrete mixtures incorporating 8 widely different fly ashes and 2 cements of high and low alkali content were investigated. The proportion of fly ash in all the concrete mixtures was 58% by weight of the cementitious materials, with a water-to-binder (cement + fly ash) ratio of 0.33 for all the mixtures, and a high degree of workability maintained by use of a superplasticizer. All test concretes were air entrained. A broad range of engineering properties was evaluated including compressive strength, Young`s modulus of elasticity, flexural strength, splitting-tensile strength, abrasion resistance, drying shrinkage, creep, air-void parameters of the hardened concrete, resistance to freezing and thawing cycling, de-icing salt scaling resistance, resistance to chloride-ion penetration, water permeability, and sulphate resistance.
