Title: Use of fly ash, slag, or silica fume to inhibit alkali-silica reactivity. Final report

Abstract

The study had two objectives: (1) to evaluate the effectiveness of particular mineral admixtures when combined with portland cements of varying alkali content in preventing expansion due to alkali-silica reactivity (ASR), and (2) to determine if set minimum amounts of various types of mineral admixtures could be established for use with cements of varying alkali content to provide protection from ASR. The expansion of mortars containing fly ash, slag, and silica fume was lower than the expansion of the control batches for portland cement having an alkali content of 0.6% and above for all replacement levels of the tested materials. Using an expansion of 0.10% as the maximum indicative of acceptable performance in inhibiting ASR, minimum amounts of Class F fly ash, slag, and silica fume were established for use with portland cement depending on the alkali content of the cement.
