Rapid, Robust, and Relevant (R3) Reactivity Test for Supplementary Cementitious Materials

Although supplementary cementitious materials (SCMs) are now commonly accepted and widely used, consensus has not been reached for methods to test their chemical reactivity. A multitude of test methods exist but often fall short on one or more of the key features of a proper test-that is, width of scope, practicability, reproducibility, and relevance of the result. A rapid, robust, and relevant chemical reactivity test applicable to a wide range of SCMs would therefore not only serve as global benchmark but it would also remove present ambiguities in regards to classification.
