Fly ash can be used to directly reduce the amount of Portland cement required for concrete, which significantly cuts down the amount of greenhouse gas released into the atmosphere. But its widespread use in Upstate New York has been hindered by confusion about its effects and usage.

Keith Bargaheiser — fly ash product representative from Headwaters Inc. — will discuss “Fly Ash: Making Concrete Sustainable” on Thursday, June 19, from 8-9:30 a.m. at the Rosamond Gifford Zoo in Syracuse.

“I plan to cut through the myths and misunderstandings about the use of fly ash in concrete. Bring your questions!” says Bargaheiser. “My slate of topics will include the effect of fly ash on concrete, including reduced permeability, higher ultimate strength and minimized alkali-aggregate reaction; the side effects, such as reduced bleeding and initial delay in strength gain; the consistency and quality of the product delivered to the batch plant; and the relative cost and availability of fly ash.”

The cost of the talk is $15 for USGBC New York Upstate Chapter members and $20 for non-members (cost includes a breakfast buffet starting at 8 a.m.) Registration and payment can be made online at http://www.greenupstateny.org.
