Description

This practice describes approaches for identifying potentially deleteriously reactive aggregates andselecting appropriate preventive measures to minimize the risk of expansion when such aggregatesare used in concrete. Both alkali-silica reactive and alkali-carbonate reactive aggregates arecovered. Preventive measures for alkali-silica reactive aggregates include avoiding the reactiveaggregate, limiting the alkali content of the concrete, using blended cement, using supplementarycementitious materials, using lithium nitrate as an admixture, or a combination of these measures. Preventive measures for alkali-carbonate reactive rocks are limited to avoiding the reactiveaggregate.
