SWARS Semi Annual Meeting 13 “Leader-Ship” – The Shipper Perspective Origins of the word: “Pozzolan”

SWARS Semi Annual Meeting 14 “Leader-Ship” – The Shipper Perspective Historical Overview Pantheon in Rome

SWARS Semi Annual Meeting 15 “Leader-Ship” – The Shipper Perspective What is Natural Pozzolan?

• Fly Ash is mostly Silica, Aluminum, Iron & Calcium (the impurities in coal that do not burn); ASTM C-618; Class F or Class C (C is from PRB coals) • Natural Pozzolan chemistry is similar to Fly Ash; ASTM C-618; Class N • Used as concrete additive before fly ash • Glen Canyon Dam had 200,000+ tons Natural Pozzolan • Mostly from volcanic origins, not “man made” • Mined, crushed, dried, & finely ground • Makes concrete more durable • “Green” product, naturally occurring • Natural Pozzolan, in a Secondary Reaction (similar to how Fly Ash reacts), also forms more “Glue” in Concrete, making it stronger

SWARS Semi Annual Meeting 16 “Leader-Ship” – The Shipper Perspective Where Does Fly Ash Come From? (Note: Fly Ash is a Man-Made Pozzolan) • Fly ash is a very fine powder residue that is captured in bag houses and precipitators by the coal-burning power plant • Utilities sell fly ash to their contracted Marketers, who in turn recycle, then sell, the fly ash for use in concrete and other applications • Fly Ash reacts in concrete after the initial cement + water reaction; Fly Ash forms more “Glue” & makes concrete stronger, denser and more durable.
