This student workbook and instructor's guide is one of six prepared for an intensive 6-week "Highway Materials Engineering" course. The course was developed primarily for State highway agency (SHA) engineers who require a basic knowledge of highway materials. The workbook/guides were developed by national experts in the various materials areas under the guidance of SHA materials engineers and FHWA materials experts. This module focuses on the basic knowledge of concrete needed by highway materials engineers. Topics discussed include the role of cement and water in concrete, admixtures, fresh concrete behavior, hardened concrete behavior and properties, freeze-thaw and other durability problems, and corrosion of reinforcing steel. This workbook/guide is the sixth in a series. The others in the series are: Module No. I II III IV V FHWA No. 90-004 90-005 90-006 90-007 90-008 Title Materials Control and Acceptance -- Quality Assurance Soils and Foundations Steels, Welding, and Coatings Aggregates and Unbound Bases Asphalt Materials and Paving Mixtures
