Aim(s)
To impart knowledge in the properties 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; Identify different types of cement based on their composition and performance. Select most appropriate ingredients, based on their 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 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.
