Concrete Engineering Technology

Concrete Engineering Technology. Instructor: Prof. Sudhir Misra, Department of Civil Engineering, IIT Kanpur. The course deals with different aspects of modern concrete technology that has evolved as a result of rapid developments in mechanized construction, use of mineral and chemical admixtures in concrete. Use of concrete in more challenging environments, better understanding of the material properties of concrete, emphasis on durability, etc. Examples of special concretes and construction methods are used to illustrate the scientific principles involved therein and their engineering treatment. To a limited extent, provisions in codes and their limitations are also discussed. A brief discussion on maintenance of concrete structures, including nondestructive testing, evaluation criteria, repair and rehabilitation will also be included for completeness. The course is designed as an elective course for final year level degree and post-graduate students of civil engineering, who have a basic background of concrete constituents and properties, and design of concrete structures.
