Design of RC Structures Questions and Answers – Water Tanks Classifications

This set of Design of RC Structures Multiple Choice Questions & Answers (MCQs) focuses on “Water Tanks Classifications”.

1. A water tank is used to store water to tide over the daily requirements.
a) True
b) False
View Answer

Answer: a
Explanation: A water tank is a container for storing water. These are used to provide storage of water for use in many applications such as drinking water, irrigation, fire suppression, agricultural farming and both for plants and livestock. It can also be used in chemical manufacturing and food preparation.

2. Which of the following is not a classification of water tanks?
a) Tanks resting on ground
b) Elevated tanks supported on staging
c) Underground tanks
d) Intze tanks
View Answer

Answer: d
Explanation: A water tank is a container to store water to tide over the daily requirements. Water tanks are classified under three heads: tanks resting on ground, elevated tanks supported on staging and underground tanks.

3. According to the shape which of the following is not a type of water tank?
a) Circular
b) Conical
c) Rectangular
d) Spherical
View Answer

Answer: b
Explanation: According to the shape, water tanks are of several types. This includes circular tanks, rectangular tanks, spherical tanks, intze tanks and circular tanks with conical bottoms.

4. Which grade of concrete is commonly adopted for construction of water tanks?
a) M30
b) M40
c) M45
d) M10
View Answer

Answer: a
Explanation: Richer concrete mix of grade M20 to M30 are commonly adopted for construction of water tanks. M20 is for plain concrete, M30 for reinforced concrete and M40 for prestressed concrete. High quality concrete provides water tightness and has higher resistance to tensile stresses developed in tank walls.

5. For the construction of concrete structure to store water or any other liquid, the imperviousness of concrete is not an important consideration.
a) True
b) False
View Answer

Answer: b
Explanation: When a concrete structure is constructed to store water or any other liquid it is necessary that the concrete is impervious. This prevents leakage and any harm to the surrounding. The permeability depends on the water-cement ratio. It is directly proportional to the water-cement ratio of concrete.

6. The liquid retaining structures are designed so as to avoid the cracking of concrete.
a) True
b) False
View Answer

Answer: a
Explanation: The liquid retaining structures are designed to avoid cracking in the concrete. Cracking in concrete is avoided to provide tensile strength. It is mainly due to shrinkage, free expansion-contraction of concrete and swelling due to moisture effect.
