20 Interview Questions For Civil Engineers

20 Interview Questions For Civil Engineers

Civil engineers are in need to know the viva questions frequently. Often the Viva Questions are so ridiculous and tough that it is almost impossible for the engineers to answer them as there are too many equations and citations. Here we are going to represent the 20 most viva questions and their answers.

Question-1: What is the FM(Fineness Modulus)?

Answer: FM( Fineness Modulus is an empirical figure obtained by summing up the cumulative percentage of materials retained on each of the sieve excluding 0.075 mm sieve and dividing the sum by 100.

Question-2: What is the FM value for Sand and Stone?

Answer: For sand the FM value varies from 2.5-4.0 and for stone FM value varies between 6.5-8.0.

Question-3: What is LAA?

Answer: LAA means Los Angeles Abrasion Test which represents the strength of stone to withstand with the abrasion that occurs during the life cycle of the stone.

Question-4: If the W/C cement ration is less what will be the strength of concrete?

Answer: If W/C ratio decreases concrete strength will rise up.

Question-5: What is Compaction?

Answer: Compaction is a process by which the volume of the soil decreases by using any mechanical devices and by pulling out the available air in the soil.

Question-6: What is Consolidation?

Answer : Consolidation is a natural process by which the soil volume reduces and it becomes in compacted form by pulling out the water and decreasing the pore spaces between the particles.

Question-7: Say name of the compaction test methods?

Answer : 1. Standard Proctor Test
2. Modified Proctor Test

Question-8: Draw The compaction Curve?

Answer:

Compaction Curve

Compaction Curve

 

 

 

 

 

 

 

Question-9: How can you measure workability of the concrete on field?

Answer: Workability can be measured by slump test.

Question 10: What is the normal slump value for concrete?

Answer: Normally slump vale varies between 50 mm-100 mm for normal concrete.

Question 11: What is the dimensions of Slump Mold?

Answer: Height=12 inch, Top width=4 inch and bottom width= 8 inch

Question 12: What are the types of slump?

Answer: Slump in concrete are of three types:

  • True slump
  • Shear slump
  • Collapse
  • slump types

 

 

 

Question 13: What is Dewatering?

Answer: Dewatering means removing the water from any specified construction place so that the construction work can run smoothly.

Question 14: What is Hydration?

Answer: Hydration is the reaction between cement and water.

Question 15: What is the distance of Farakka Dam from the border of Bangladesh?

Answer: The distance is 16.5 km from the districh Chapainawabgonj of Bangladesh border.

Question 16: What test is done to measure the required compaction on field?

Answer: Compaction test by sand cone replacement method.

Question 17: Why do we use steel in concrete? why not other metals?

Answer: We use steel in concrete as the co-efficient of thermal expansion of concrete and steel is almost same and steel has very good strength to withstand with the tensile loads.

Question 18: How do designers design the compressed member when there is no use of steel?

Answer: Then it was designed to produce very small to no tensile stress in the section so that the section will be very large.

Question 19: What is Geo-textile?

Answer: Geo-textile is a permeable synthetic fabric that is produced from plyestar,ploy ethylene to separate the soil or to filter the materials, or to protect the banks from being eroded.

Question 20: What types soil is sand?

Answer: Sand is cohesionless soil.

Sediment Load, Bed Load and Suspended Load-definitions

suspended load-bed load

Sediment Load:

All of the natural channels,streams generally carries sediment with the flow it has.It is generally a burden of flowing water which is carried by the velocity of flowing water and is termed as sediment load.

Bed Load:

Bed load is that type of sediment load in which the sediment is carried along the bed of the channel with occasional jumps into the channel.

Suspended Load:

Suspended load is the one in which the material is maintained in suspension of the flowing water. (139)

21st BCS Civil Engineering Written Questions and Solve–

BCS QUESTIONS CIVIL ENGINEERING WRITTEN

Transportation Engineering:

Question-1: a) Write down the function of ballast in a railway track?

Answer:

What is Ballast?

Ballast is the foundation of railway track and it distributes the load to the underlying layers in a railway track.Generally rocks or gravels are used as a ballast material.The gravels covers the sub-grade of railway track and distributes the load the underlying layers.

Functions of Ballast:

  • To provide a hard layer for the sleepers to rest on.
  • To distribute the loads.
  • For easy maintenance of railway track without disturbing the underlying layers.
  • To prevent the growth of plants and vegetation etc.
  • To hold the sleepers in position during the train passing.
  • To maintain the lateral stability of the railway track.
  • To ensure proper drainage of water.

Question:1(b)–Define Yard.Discuss the important points needs to be considered in designing the Marshalling Yard.

Answer:

Yard:

A yard is a space/area that contains a complex series of railroads, tracks and also contains sheds for maintaining,repairing storing,joining of rail coaches and locomotives.

Marshall Yard are of three types:

  • Hump Yard
  • Gravity Yard
  • Flat Yard

Important factors to be considered during designing of Marshalling yard:

(If anyone know please contribute the answer of this section in comment box)

Question:1(c)–Design the rate of super-elevation for a curve of radius 400 m and speed of 80 km/hr. Also check the co-efficient of lateral friction.(G.C. Singh,pp-167)

Answer:-

For mixed traffic conditions super-elevation, e=(0.75V)^2/127R = (0.75X80)^2/(127X400) = 0.0708 = 1 in 14.12

check for co-efficient of lateral frictions,  = (V^2/127R)- 0.067 = (80^2/127X400)-0.067 = 0.059

As the value is less than 0.15 the safe value,the design in safe with a super-elevation of 1 in 15 (answer). (247)

Surveying and its Classifications

surveying classifications

Surveying:

The art of determining relative positions of objects on the surface of the earth by taking measurements in the horizontal and vertical planes , is called surveying.

Surveying may primarily divided into the following types:

a) Plane Surveying:

The surveys in which the curvature of earth is not taken into consideration are known as plane surveys. These surveys extend over small areas.he degree of accuracy obtained in this type of surveying is comparatively low.Generally areas less than 250 sq. kilometers are treated as plane.When the surveys extend over limited areas,the difference in length between the arc and subtended chord for any two points on the surfaceof the earth is only about 0.1 m for a distance of 18.2 km,0.3 m for 4.3 km and 0.5m for 91 km. Similiarly,the difference between the sum of the angles of a spherical triangle on the earth’s surface and that of the angles of the corresponding plane triangle is only one second for every 195.5 sq. km of area.

b)Geodetic Suveying:

The surveys in which the curvature of the earth is taken into account is called geodetic surveying.These surveys extend over large areas( more than 250 square km) and where the degree of accuracy required is great.
