Civil Engineer Interview Questions & Answers

  1. Question 1: What Do You Understand By “preset” During The Installation Process Of Bridge Bearings?

Answer: During the installation of bridge bearings, the size of the upper plates is reduced to save material costs. This process is known as preset.

  • Question 2. What Reinforcements Are Used In The Process Of Prestressing?

Answer: The major types of reinforcements used in prestressing are:

  • Spalling Reinforcement: The spalling stresses leads to stress behind the loaded area of the anchor blocks. This results in the breaking off of the surface concrete. The most likely causes of such types of stresses are Poisson`s effects strain interoperability or by the stress trajectory shapes.
  • Equilibrium reinforcements: This type of reinforcements are required where several anchorages exist where the prestressing loads are applied in a sequential manner.
  • Bursting Reinforcements: These kinds of stresses occur in cases where the stress trajectories are concave towards the line of action of load. In order to reduce such stresses, reinforcements in the form of bursting are required.


  • Question 3. Why Should Pumping Be Not Used In Case Of Concreting Works?

Answer :

During the pumping operation, the pump exerted pressure must overcome any friction between the pumping pipes and the concrete, also the weight of the concrete and the pressure head when the concrete is placed above the pumps. Since only water pumps able, all the pressure generated is by the water that is present in the concrete. The major problem due to pumping are segregation effects and bleeding. In order to rectify and reduce these effects, generally, the proportion of the cement is increased in order to increase the cohesion, which leads to the reduction of segregation and bleeding. Also if a proper selection of the aggregate grading can vastly improve the concrete pump ability.

  • Question 4. What Are The Different Type Of Slump Test Indications?

Answer :

Slump tests are performed to empirically measure the workability of fresh concrete. It is used to measure the consistency of the concrete. In general, there are three different types of slumps that occur in slump tests.

They are as follows:

  • True Slump: This type of slump is characterized by the general drop of the concrete mass evenly without visible signs of deterioration or disintegration.
  • Shear Slump: It indicates that the concrete mix is deficient in cohesion. This type of slump leads to segregation and bleeding. Henceforth in the long run affecting the durability of the concrete.
  • Collapse Slump: This type of slump is indicates that the mix of concrete is simply too wet. The mix is considered to be harsh and lean.

Note: This question is mostly asked, especially for BE candidates.

  • Question 5. Why Are Pull-out Tests Performed For Soil Nails?

Answer :

Pull out tests are performed for primarily the following reasons:

  • In order to detect and verification of the bond strength among the soil and the grout adopted during the design of soil nails. This is considered to be the primary objective of performing pull out tests for soil nails.
  • For the detection of any slippage or occurrence of creeps.
  • To detect the elastic and deformations (plastic) of any of the test nails employed. Observations are made during the loading and unloading cycles of the soil nails repetitively.
  • To achieve the perfect balance the test nails should always be loaded so that the ultimate soil/grout mixture with an upper limit of 80%.

Note: This question is mostly asked, especially for BE candidates.

  • Question 6. What Is The Meaning Of Soil Reinforcement?

Answer :

Soil reinforcement is the act of improving soil strength to enable it to support or carry more load.

Two common examples are:

  • Mixing a soil amendment such as lime into weak clayey soil and re-comPActing to improve soil-bearing caPAcity (often done under the road base in highway construction)
  • Installing plastic or composite webbing layers (called geo-grid material) alternating with comPActed soil to produce a stronger sloped soil structure (often done on steep roadway embankments to improve strength and stability)

  • Question 7. What Is Braced Excavation All About?

Answer :

Excavations are braced to prevent the cave-in of surrounding unstable soil.

  • Question 8. What Are The Uses Of Alloys In Daily Life And How Are Alloys Made?

Answer :

Alloying is not always done to produce a ‘superior’ material, but to produce materials having a desired requirement in the industry or elsewhere. A classic case is of lead solder (containing lead & tin), in which the melting point of the constituent elements are lowered, not necessarily a desirable property.

Alloying can be carried out using hot press method (a sheet of material is sandwiched with alloying material), rolling the heated base metal in a drum full of alloying metal powder, using hot spraying, galvanizing (dipping the base in a molten solution of alloying material) etc. Sometimes the alloying material is added in small proportions to the molten base metal (e.g., in the production of different types of steel).

  • Question 9. What Is The Tallest Man-Made Structure In The World?

  • Question 15. What is the crank length in the slab?

The minimum length of a crank is 300 mm.

The formula of Crank length = (d1+d2+5) *10mm where d1 is the diameter of smaller bar and d2 is the diameter of the largest bar.

Also, the slope of the crank is 1:10 (one of the common civil engineering interview questions.)

  • Question 16 What is the strength of cement?

The cement’s strength is tested on hardened Cement-Sand mortar’s cubes, and these are prepared out of the cement which has a strength of 53MPa. It is derived from 53 Grade OPC Cement giving 28-days of compressive strength of the cement. It is one of the most common civil engineering interview questions.

Question 17. How is the strength of cement measured?

The measurement is done after the curing process has taken place for 7 days or 28 days. The load should be applied slowly at the rate of 140 kg/cm2 per minute until the Specimen fails. We get the compressive strength of the concrete or the cement at the load failure divided by the specimen’s area.

  • Question 18. What are segregation and bleeding?

Bleeding, in civil engineering, is a process and state of mixing water in the concrete in which the concrete rises above the material’s surface.
