FROST RESISTANCE OF ROLLER-COMPACTED HIGH-VOLUME FLY ASH CONCRETE
Four high-volume fly ash roller-compacted concrete mixtures were designed in the laboratory with fly ash contents fixed at 63 percent of the total cementitious material. Two mixtures had a cementitious material content of 12 percent (as a proportion of the total mass of dry materials and two mixtures had a cementitious material content of 15 percent. Two of the mixtures were air-entrained and two were non-air-entrained mixtures. The concretes were placed in a cylindrical mold that vibrated laterally while a longitudinal compressive force was applied to each specimen. Mixtures were tested for strength, absorption, permeability, determination of the air-void characteristics, and frost resistance. The frost resistance of air-entrained concretes was found to be very good, regardless of the cementitious material content. These concretes contained only a small amount of irregularly shaped compaction air voids. The non-air-entrained concretes displayed adequate frost resistance. The authors recommend the use of air entrainment for roller-compacted, high-volume fly ash concretes.
