WORKSHOP
4:00 PM (1.0 PDH)

Title : Lightweight Cellular Concrete for Geotechnical Application

Speaker : Mr. Greg Halsted, P.E. w/ Portland Cement Association

BIO : Greg Halsted, P.E., is the Manager of Pavement and Geotechnical Markets for the Portland Cement Association (PCA). He is responsible for expanding market share for use of portland cement in all paving and engineered cement applications including conventional concrete, rollercompacted concrete, pervious concrete, cement-modified soils, cement-stabilized subgrades, cementtreated base, fulldepth reclamation, lightweight cellular concrete, slurry trenches, flowable fill, deep soil mixing, and waste solidification/stabilization. Halsted has over 20 years of experience in the use of cement in the pavements, geotechnical, and concrete industry. He has knowledge of planning, design, materials testing, and construction; has participated in numerous training and construction workshops involving State and Provincial transportation agencies, Public Works departments, Universities, material suppliers, and consulting firms; and has authored several publications related to cement and concrete construction. He currently serves as a committee member of Transportation Research Board (TRB) AKG90 - Stabilization of Geomaterials and Recycled Materials, AKP20 - Design and Rehabilitation of Concrete Pavements, and is a voting member of American Concrete Institute (ACI) 325  Concrete Pavements. Halsted holds a Bachelor of Science in Civil Engineering Technology from Southern Polytechnic State University, and is a licensed engineer in the state of Georgia. Prior to joining PCA, he held civil and geotechnical engineering positions with the Concrete Reinforcing Steel Institute and the Georgia Department of Transportation.

ABSTRACT : Lightweight cellular concrete, or LCC, is a mixture of portland cement, water, and air that can act as a lightweight, strong, durable, and inexpensive soil or fill replacement for geotechnical applications. LCC saves time, money, and natural resources by replacing aggregates with air bubbles in numerous project applications. This presentation will introduce construction professionals and the design community to LCC and assist them in specifying this product for daily use.


PRESENTATION
5:00 PM (1.0 PDH)

Title : Smart Cement, Detection and Quantification of Corrosion and Polymer Treatment for Expansive Clay Soils: Innovative Technology Development, Modeling and Applications

Speaker : Mr. Cumaraswany Vipulanandan, Ph.D., P.E. w/ University of Houston

BIO : Cumaraswamy Vipulanandan (Vipu) is a professor of civil and environmental engineering at the University of Houston where he is Director of the Center for Innovative Grouting Materials and Technology (CIGMAT) and also the Texas Hurricane Center for Innovative Technology (THC-IT). His work has resulted in more than 280 refereed papers and over 160 presentations at national and international conferences, and he recently received two U.S. patents on Smart Cement and Detection and Quantification of Corrosion in Materials. His current research interests are in smart materials, foundations, pipelines, grouting, and environmental engineering. Vipu received his MS and PhD in Civil Engineering from Northwestern University and is a registered professional engineer in the State of Texas.

ABSTRACT : Smart cement with highly sensing properties is now available, and its performance has been well-tested in laboratory and field models. In addition to being piezoresistive, it is also sensitive to stress, chemical and temperature changes. A non-destructive electrical method has been created to rapidly detect and quantify corrosion in metals and non-metallic materials and the technology can be easily implemented in the field. Also, new polymer treatment methods are being developed for rapidly treating the expansive clay soils to reduce swelling and enhance mechanical properties. With these new developments, analytical models can now characterize smart cement, corrosion and soil behaviors.
