From staff reports
Joseph J. Biernacki, a professor of chemical engineering at Tennessee Technological University, will discuss portland cement concrete hydration models from 11:10 a.m. to noon, Tuesday, Sept. 14, in Academic & Research Center 102.
A 10-time National Science Foundation (NSF) grant award recipient, Biernacki will speak on the chemistry and physical nature of portland cement as related to hydration and major milestones in the development of hydrogen models.
The hardened properties of portland cement concrete are the result of chemical reactions known as hydration. These properties include strength and strength development, and chemical and physical durability behavior.
Hydraulic cement dates back to Roman times, but we still have limited ability to predict hydration behavior. Biernacki will review the chemistry and physical nature of portland cement, as well as major milestones in the development of hydration models, and also present a single particle model for hydration.
A fellow of the American Concrete Institute, Biernacki also has received national awards for education and research. He is also a member of the American Ceramic Society, for which he is presently the cement division trustee. He holds master's and doctoral degrees in engineering from Cleveland State University.
