Access Period: 30 days


This session will showcase new information on the use of raw natural pozzolans in concrete mixtures. Natural pozzolans are seeing a resurgence as demand for supplementary cementitious materials for concrete increases. The role of these materials in concrete performance will be presented, including their impact on cement hydration and concrete strength and durability. Presentations will also highlight practical use of these materials in concrete construction. The intended audience includes engineers, contractors, researchers, and students interested in the performance of natural pozzolans.

Table of Contents

Learning Objectives:

(1) Recall new and emerging sources of supplementary cementitious materials for concrete production;

(2) Describe how raw natural pozzolans affect concrete early and late-age properties, including effect on strength gain and durability

(3) Describe the differences between the many types of raw natural pozzolans; unaltered pozzolans, such as pumice and perlite, altered volcanic pozzolans, and sedimentary pozzolans, such as calcined clay.

(4) Evaluate the properties of concrete in resisting ASR attack, sulfate attack, and chloride ingress with use of blended cements containing raw natural pozzolans.
