Title: Design and Properties of High-Volume Fly Ash High- Performance Concrete
Author(s): J. G. Cabrera and C. D. Atis
Publication: Special Publication
Appears on pages(s): 21-38
Keywords: abrasion; fatigue-resistance; fly ash; high-performance; high-strength concrete; workability
Abstract:This paper discusses a new method for the determination of the optimum W/C plus FA for maximum compaction of no slump concrete made with high volumes of fly ash. It explores the effect of fly ash fineness and particularly, carbon content on the explores the effect of fly ash fineness an particularly, carbon content on the compressive strength of the mixtures made with 50% and 70% replacement of normal portland cement with fly ash. By using an appropriate surfactant the no slump concrete mixtures are rendered workable and suitable for structural applications. The strength attained at 28 days is 60 Mpa or more, and therefore these mixtures are considered to yield high-strength concrete. The performance of the high-volume fly ash concrete is assessed in terms of abrasion and fatigue resistance that are the most appropriate performance indicators for concrete that will be used for the construction of pavements.
