The main advantage of prestressed concrete piles over traditional reinforced and concrete steel piles is __________

The main advantage of prestressed concrete piles over traditional reinforced and concrete steel piles is __________ Correct Answer Moment carrying capacity

The main advantages according to Gerwick of prestressed concrete piles over traditional reinforced concrete and steel piles are high load and moment carrying capacity, standardization in design for mass production, excellent durability under adverse environmental conditions, crack free characteristics under handling and driving, resistance to tensile loads due to uplift combined load moment capacity, particularly advantages for deep foundations to carry heavy loads in weak soils.

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. Prestressing decreases cracks in concrete under all stages of loading. C. Prestressed concrete requires only 1/3 rd of the concrete required for R.C.C.
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.
