Description

This report gives an overview of the origin and properties of fly ash, its effect on the properties of hydraulic cement concrete, and the proper selection and use of fly ash in the production of hydraulic cement concrete and concrete products. Information and recommendations concerning the selection and use of Class C and Class F fly ashes generally conforming to the requirements of ASTM C 618 are provided. Topics covered include a detailed description of the composition of fly ash, the physical and chemical effects of fly ash on properties of concrete, guidance on the handling and use of fly ash in concrete construction, use of fly ash in the production of concrete products and specialty concrete, and the recommended procedures for quality control. Relevant documents of standards-making bodies referred to in this document are cited and listed.

Keywords: abrasion resistance; admixture; alkali-aggregate reaction; concrete pavement; controlled low-strength material; drying shrinkage; durability; efflorescence; fineness; fly ash; hydraulic cement; mass concrete; mixture proportion; pozzolan; precast concrete; quality control; reinforced concrete; roller-compacted concrete; soil cement; strength; sulfate resistance; workability.
