Abstract
Recognizing natural pozzolans and their qualities is one of the most important dilemmas in
the field of cement and concrete. Although dierent methods have been published towards this aim, research
shows some anomalies between the judgments of these methods. This paper aims to compare evaluation
methods of natural pozzolans by considering their performance in concrete as a decision criterion in order
to develop a guideline for their qualication. Therefore, rstly, the main available methods are described.
Then, the pozzolanic activity of natural pozzolans is investigated using these methods and compared with
the performance in concrete. Finally, a guideline is proposed, based on the discussed methods.
