|Concrete Technology||Learning Schedule|
Concrete is one of the most vital materials used in construction. Concrete is made up of cement, coarse aggregate; fine aggregate, water and admixtures. The strength of concrete is directly depends upon the properties of these materials and their proportion in the concrete. In this course students will learn the various properties of concrete ingredients and various properties of concrete itself and their testing including non-destructive testing such as ultrasonic pulse velocity test, rebound hammer test etc. They will also learn the various mix design methods to design the concrete for different construction works.
- To understand the properties of ingredients of concrete.
- To study the behavior of concrete at its fresh and hardened state.
- To study about the concrete design mix.
- To know about the procedures in concrete at different stage.
- To understand special concrete and their uses.
On completion of this course, the students will be able to
- To identify suitable materials to be used in the cement concrete by conducting various tests as per BIS code.
- Test all the concrete materials as per BIS code.
- Design the concrete mix using ACI and BIS code methods.
- Determine the properties of fresh and hardened of concrete.
- Design special concretes and their specific applications and use of admixtures.
- Ensure quality control while testing/ sampling and acceptance criteria for pre and post construction work.
- Use of non-destructive testing equipment.
