most important interview question

1. Described what a projection line is?

Projection line can  described as the way in which the earth is displayed on a flat piece of paper that is project line.

2. plz say the various steps involved in the concreting process?

The important steps involved in the concreting process are as follows:

• Batching in  plant
• Mixing
• Transporting and placement of concrete
• Compacting

3.  reinforcements that are used in the process of prestressing.

 three  typesof reinforcement that are used in the prestressing process.

• Spalling Reinforcements.
• Equilibrium Reinforcements.
• Bursting Reinforcements.

4. describe the soundness of cement?

Cement soundness can be described as a property which ensures that the cement does not go through any appreciable expansion or experience any change in volume once it has been set. This process help get rid of any possibilities of the mortar or concrete from getting blur.

5. Explain Fatigue. Can you point out some of the structures that may be subjected to fatigue?

Fatigue can be described as the gradual damage to a structure that occurs when it is subjected to cyclic loading (repeated loading and unloading). Some of the structures that may be subjected to fatigue include:

• Bridges that are heavily loaded
• Hydraulic Presses
• Aircrafts
• Concrete Reservoirs
• Pylons
• Turbines
• Overhead cranes
• Transmission towers
• Offshore platforms
• Burners trains

6.  various types of slump test indications?.

Slump tests are begin to empirically measure the consistency of fresh concrete before it sets. They can also be used to check for an improperly mixed batch of concrete as well. There are three different types of slumps that occur in slump tests listed as below:

• True Slump
• Shear Slump
• Collapse Slump

7. Explain the concept ofsuper built up area and  built-up area.

Built up area cover the carpet area as well as any space occupied by walls, pillars, and ducts. In most cases, the built-up area is calculated as an more of 10% of the carpet area.

The super built-up area covers the built-up area as well as any areas that used by building amenities such as life  living passages, lobby, stairs, gym, clubhouse, etc.

8. What are some  common roof types?

There are several types of roofs available. Some of the commonly used ones include:

• Gable roof
• Gambrel roof
• Shed roof
• Half-hipped roof
• Dutch Hip roof
• A-Frame roof
• Skillion roof
• Folded Plate roof
• Gull wind roof
• Bell cast roof
• Sawtooth roof

Slump cone test for workability ?  Concrete slump test or slump cone test is to compose the consistency or    workability    of concrete mix ready at the laboratory or the construction site during the procedure of the work. Slump-cone-test-detail   slump cone test is the most simple workability test for concrete, involves general cost and provides instant results. Generally  concrete slump cone test value  is used to search the workability, which indicates w/c ratio, but there are more factors including, mixing methods, dosage, admixtures    properties of materials  etc. also effect the concrete slump value. Slump cone test propertises The  concrete slump cone test  quantify the consistency of fresh  concrete  previous  it sets. It is featured to check the  workability  of freshly ready mix  concrete , and therefore the ease with which  concrete  flows in casting time. It can also be used as an indicator of an inaccurate mixed batch. image source-google| image by  Engineer Moi

Thumb rule for every civil Engineers Thumb rule  Introducti n Thumb rules play a most important role during work in construction site. Thumb rules enable you to calculate idea using a simple maths formula and make smart conclusion whenever needed. Remember, Thumb rules is not give the accurate result, but you can use them for roughly results. There are many thumb rules which we apply in construction site. more knowledge of civil engineeering vist civilengineersgyan.blogspot.com  Thumb rule features  thumb rule is an approximatly & comparing method in civil engineering. In thumb rules, The units are not the same when we compare to get the  possitive results.Here I am discussing the most frequently used Thumb rules on construction site.
