Which of the following statements is/are true about the advantages of prestressed concrete structure? A. In the prestressed concrete structure, the deflection of beams is considerably reduced. B.

Permeability in concrete is studied towards providing for, or guarding against, which of the following features? 1. The penetration by materials in solution may adversely affect the durability of concrete; moreover, aggressive liquids 'attack' the concrete. 2. In the case of reinforced concrete, ingress of moisture and air will result in corrosion of steel leading to an increase in the volume of steel, resulting in cracking and swilling of the concrete cover. 3. The moisture penetration depends on permeability and if the concrete can become saturated with water it is less vulnerable to frost action.
