civil engineering Question Answer part 1
1. Define damp proof course. What are its causes of dampness?
Definition :-The courses which are laid to check the entry of water or moisture into the building are called damp proof courses. Causes:- faulty design of structure faulty construction or poor workmanship use of poor quality materials in construction.
2. Define Slip form?
This is a formwork system which can be used to form any regular shape or core. The formwork rises continuously, at a rate of about 300mm per hour, supporting itself
3. Mention the significance of bond in masonry structures.?
Masonry is defined as the construction of building units bonded together with mortar. The selection of material for the masonry will depend on strength, water proofing, thermal insulation, fire resistance, durability and economy.
4. What are the causes of dampness?
Moisture up from the ground to the walls.
Rain travel from wall tops.
Rain beating against external walls.
5. Define acoustics. ?
The term acoustics is defined as the science of sound, and it describes the origin, propagation and sensation of sound.
6. Write the types of scaffolding. ?
Types of scaffolding: - Single scaffolding or Brick layer scaffolding, Double scaffolding or Masons scaffolding, Ladder scaffolding,Cantilever or Needle scaffolding.
7. Define flooring ?
The properly supported horizontal surfaces which divide the building into different levels for providing accommodation one above the other within space are called floors.
8. What is the purpose of providing construction joints?
Joints in concrete building construction are construction joints, expansion joints, contraction joints and isolation joints. They prevent cracking of concrete.
9. Define scaffolding.
Scaffolding:-It is defined as the temporary structure employed in the building construction for supporting workers, materials and tools etc., during its construction alteration, demolition, painting and repair etc.,
10. Define – Stretcher bond. ?
In this bond, all the bricks are laid with their length parallel to the longitudinal direction of the wall. Since stretchers are visible in duration it is known as stretcher bond.
11. Define plinth. ?
Plinth:- It is the horizontal course of stone or brick provided at the base of the wall above ground level. It indicates the height of the ground floor level above the natural ground level. It protects the building from dampness.
12. What are the conditions for good acoustics of an auditorium? ?
Conditions for good acoustics of an auditorium: - The initial sound should be of adequate intensity or loudness. It is important for a speaker to be heard over a long distance. The sound produced should be evenly spread over the whole area covered by audience. If the sound is not evenly distributed echoes will be established. The initial sound should be clear and distinct. For music hall, the initial sound should reach the audience with same frequency and intensity. All undesired sound should be reduced.
13. Write any some materials used for joints. ?
Bituminous felt Metal strips Fiber board these are some of the materials used for joints.
14. What are monolithic wall? Write its classifications?
Monolithic walls:-Walls built of a material requiring some kind of shuttering in the initial stages.
Masonry can be classified into the following types stone masonry. Brick masonry. Hollow block concrete masonry. Reinforced masonry, composite masonry.
