Title: Required Quality Control for Fly Ash
in Portland Cement Concrete
Author(s): James N. Covey
Publication: Concrete International
Appears on pages(s): 11-15
Keywords: beneficiation; burnability; coal; fly ash; mix
proportioning; pozzolan cements; quality control.
Abstract:Fly ashes, like cements, may best be classed as being plant-specific. It is incumbent upon the utility, the supplier, to institute quality control measures that can certify the product to the user. Likewise, the user must know and understand the physical and chemical characteristics of all materials to develop the proper mix proportions. The author discusses the production and use of fly ash as well as differences in the material throughout the U.S. If fly ash is to be used as a pozzolanic material, quality control and proper mix proportioning are of primary importance.
