After undergoing the subject, the students will be able to:

• evaluate physical properties of cement concrete as per IS codes
• conduct various tests on aggregate in laboratory to evaluate their characteristics
• interpret the grading charts of different aggregates and evaluate fineness modulus of aggregates
• evaluate workability and strength of concrete
• recognize bleeding, segregation, harshness defects in fresh concrete
• explain hydration process of cement, water to cement (w/c) ratio and analyze relationship between compressive strength and w/c ratio
• conduct various destructive and non-destructive (NDT) test
• design mix of concrete as per IS code
• describe the use of different admixture to enhance the properties of concrete
• explain the feature of special concretes
• demonstrate how to carry out various concreting operation

Instructional Strategy:

This subject is of practical nature. While imparting instructions, teachers are expected to organize demonstrations and field visits to show various stages of concreting operations. While working in the laboratory, efforts should be made to provide extensive practical training to students so as to make them confident in the preparation and testing of concrete. Teachers should also organize viva examination so as to develop understanding about concepts and principles involved.

Means of Assessment:

1. Assignments and quiz/class tests
2. Mid-term and end-term written tests
3. Actual Practical Performance
4. Report writing
5. Viva-Voce
