NRMCA Research Lab Publishes Report on Natural Pozzolans

The NRMCA Research Laboratory recently published a report titled A Limited Performance Evaluation of Natural Pozzolans Using the Bulk Resistivity. Some of the main findings are:

1. Natural pozzolans can be used to attain adequate compressive strength despite some of them having a higher water demand.
2. The 28-day accelerated bulk resistivity test values were found to be very effective at identifying reactive supplementary cementitious materials from fillers.
