Description: The use of lithium compounds to reduce expansion of concrete caused by alkali-silica reaction (ASR) has been well documented. However, there has been additional research in recent years to better understand the mechanism by which lithium inhibits expansion, the variables involved, and to more accurately determine how its use relates to other concrete properties. While lithium is most commonly added to the fresh concrete as an admixture, it has also been applied successfully to hardened concrete, and added to the raw material or interground with the cement at the cement plant. This 15-page annotated bibliography lists papers, reports, and patents related to these applications, beginning with the Strategic Highway Research Program activity in the early 1990s
