Objective:

To introduce students to the processed building materials. To enable students to get exposure to applications, economy and effect of these materials on environment. With the knowledge of both natural and processed building materials, students will be able to choose the best materials from numerous available products suitable to a project.

Course Contents:

1. Cement: History and development of cement, ingredients, manufacturing process, types of cements and their applications, cost aspect. Future of cement and effect on environment. Testing the properties of cement.

2. Aggregates: History, source, fine & coarse aggregates, classification, procurement, properties, tests to check quality of aggregates. Cost aspect.

3. Mortar: History, mud, lime and cement mortars, preparation and use of mortars, precautions, selection, defects and tests for mortars. Cost aspect.

4. Steel: Purpose, history, types, manufacturing of steel, properties of steel testing the properties of steel and future of steel. Cost aspect.

5. Concrete: Lime and cement concrete. Cement concrete, nominal mix, design mix, preparation of concrete, proportioning of constituents, mixing, consolidation, and curing. Effect of water cement ratio on strength, permeability, workability and durability of concrete. Testing of fresh and hardened concrete. Cost aspects.
