Two compounds, zinc sulfate and aluminum sulfate, were found to be effective admixtures for fresh concrete. Zinc sulfate also appeared to significantly reduce the subsequent expansion of mortar bars and could be a suitable penetrating agent for arresting alkali-silica reaction in hardened concrete.Identifies a number of chemical compounds for their effectiveness in inhibiting alkali-silica reaction in concrete, either as admixtures in the concrete mix or as penetrating agents to stop further progress of the reaction in already-affected or damaged concrete.
