What is it about?
There are many methods proposed for the measurement of the relative reactivity of supplementary cementitious materials. This manuscript studies the potential of using a durability based alkali silica reaction test as a method for measuring the quality of potential Supplementary Cementitious Materials.

Why is it important?
The majority of experiments regarding the reactivity of pozzolans are associated purely with the consumption of calcium hydroxide. This new proposed test method will assess all of the potential reactions that these SCMs can go through along with the SCMs ability to mitigate the ASR reaction.
Perspectives
Writing this manuscript was an interesting experience as it forced me to not only consider the scientific ramifications of my work but also how my work might influence existing ASTM specifications. Through this I hope that this work may help advance the implementation of performance based specifications.
