Abstract
 Natural Pozzolans for Sustainable Development Track: Sustainable Development and Humanitarian Affairs Author(s): Ronald Harris, Thomas Eatmon, Christian Seifert Alleviating poverty and reducing environmental pollution in less developed countries are important goals of sustainable development. Lower building costs and reduced pollution should make development more sustainable. Most often, concrete is made with Portland cement, produced in developed countries. Byproducts of Portland cement production are Carbon Dioxide and particulate matter, environmental pollutants that harm human health. Natural pozzolans are substitutes for Portland cement, that include diatomaceous earth, volcanic ash, and rice husk ash. We consider technology transfer among countries in the Western Hemisphere. North America is more developed than Central or South America and thereby provides a model for technology transfer in less developed parts of the world. We use Geographic Information Systems to map natural pozzolans and complementary materials for concrete production. Indicators identify regions where poverty is prevalent and natural pozzolans are available to make concrete, without utilizing Portland cement.
