Reactivity of Supplementary Cementitious Materials [TechNote]

The purpose of this TechNote is to support materials suppliers, producers, and infrastructure owners during materials acceptance and quality control efforts with deciding which reactivity test can be performed to characterize a supplementary cementitious materials (SCM). In doing so, this TechNote offers background on reactivity and reactivity testing and synthesizes reactivity test methods that can be used to characterize novel materials that replace cement within concrete.
