Course Aim: To impart knowledge on properties and performance of concrete and its ingredients in specifying, producing, using and caring of high-performance concrete for structures.
Intended Learning Outcomes: On successful completion of the course, the students should be able to; ➢ select the most appropriate ingredients based on their composition and properties, for the production of concrete to suit the application. ➢ specify concrete with different characteristics for diverse conditions and applications. ➢ design concrete mixes to achieve specified performance requirements. ➢ evaluate the properties and performance of concrete, working life and judge compliance. ➢ propose suitable procedures for making, delivery, placing, finishing and caring of concrete, giving due consideration for the application. |
