    1. Explain corrosion in reinforcement. Show the corrosion process and subsequent damage

    in the concrete with the help of neat diagrams. Also enlist preventive measures for

    controlling corrosion.

    2. Describe Alkali-Aggregate Reaction. What preventive measures could be taken for Alkali-

    Aggregate Reaction in concrete?

    3. Write short notes on:

    a. Sulfate attack

    b. Methods for preventing sulfate attack

    c. Delayed ettringite formation

    d. Autogenous shrinkage

    e. Chloride ingress

    f. Deicing effect

    4. Define durability of concrete. What are the physical and chemical causes of inadequate

    durability?

    5. Explain in detail:

    a. Temperature problems in concreting

    b. Hot-weather concreting

    c. Cold-weather concreting
