Durability of Portland Cement Concrete: Aggregates, Cements, and Pozzolans

The Nebraska Department of Roads in 2001 initiated an effort to improve the durability of concrete for state paving projects. The objectives were to evaluate the alkali-silica reactivity (ASR) potential of selected aggregates, and to identify the specific amounts of supplementary cementing materials, such as fly ash, slag and silica fume, to effectively mitigate ASR. The testing included 4 sources of fine aggregates, 1 source of limestone, 5 sources of portland cement, 2 sources of class C fly ash, 1 source of Class F fly ash, 1 source of slag, and 1 source of silica fume. ASTM C1293 and performance tests, including compression strength, flexural strength, split-tensile strength, freeze-thaw resistance and chloride ion penetration, were conducted on the same concrete mixes. Using 17 to 23.5% of F ash, 20 to 35% of slag, or 20% of C ash plus 3% silica fume effectively reduced the ASR expansion without compromising the concrete performance per Nebraska 47B Specifications.
