Abstract:
Presents comparative data on high-volume fly ash concrete made with ASTM Type I cement, and control concrete for mass concrete applications made with ASTM Type I and a modified version of ASTM Type II cements. The concrete was supplied by a ready-mix concrete producer for casting five large rectangular monoliths, each measuring 2.5 x 4.0 x 5.0 m. The maximum and effective temperature rises were measured, and in situ strength was determined by testing drilled cores. Also, the mechanical properties and durability of the concrete for the monoliths were determined. The adequate strength development and low temperature rise characteristics of high-volume fly ash concrete had excellent resistance to freezing and thawing cycling when tested in accordance with ASTM C 666, and no difficulty was experienced in entraining air in the system.
