2. Civil Engineer Interview Questions
1. Explain what do you mean by flashing?
⇒ Flashing is an extended construction that is performed to hide and covers joints in a building from water penetration. Flashing is established at the intersecting roofs, walls, and parapets.
2. What is Bursting Reinforcement?
⇒ Tensile stresses are caused at the time of the pre-stressing process and the maximum bursting stress arises where the stress trajectories are concave towards the line of action of the load. Reinforcement is required to withstand these lateral tensile forces.
3. What are the major problems in using pumping for concreting works?
⇒ In pumping operation, the force exerted by pumps must decrease the friction between concrete and the pumping pipes, the weight of concrete, and the pressure head when keeping concrete above the pumps.
In fact, as only water is pumpable, it is the water in the concrete that moves the pressure.
The major issues associated with pumping are the effect of segregation and bleeding.
To fix these damaging effects, the proportion of cement is raised to improve cohesion in order to decrease segregation and bleeding.
On the other hand, a proper selection of aggregate grading helps to improve the permeability of concrete.
4. What are the responsibilities of a construction manager?
⇒ The duties of a construction manager are Cost Estimates, Pre-purchase of selected materials, Selection of bidders for the bidding phase, Analysis of proposals, Construction contract negotiations, Construction Scheduling and Monitoring Cost control of construction, and Construction supervision.
5. What is a Shear Slump?
⇒ Shear slump means that the concrete mix is lacking in cohesion.
Consequently, it may experience segregation and bleeding and thus is avoided for the durability of concrete.
6. Why is concrete weak in tension?
⇒ Concrete is produced up of a collection of materials (many aggregate types, cement, pozzolans, water, air…), which are attached together with a cement paste.
The “interface” zone is the most vulnerable link in the structure.
When compressing, that interface only helps to share compressive stresses from one aggregate to the following. That does not need extraordinary strength.
Under tension, the aggregates are attempting to pull out from each other, and the glue is what keeps the whole system jointly.
Since it is extremely weaker than the aggregates, it is where the failure begins at much lower stresses.
7. What is Grouting?
⇒ Grout may be defined as a fluid form of concrete that is employed to seal voids.
8. What is the recommended slump for the column?
⇒ 75 to 125 mm
9. The bearing capacity of granite is generally?
⇒ 30 to 35 kg/cm2
10. What are the specifications of the tamping rod employed in cube filling for the cube test?
⇒ According to the IS code 2386, a 16 mm steel rod with a rounded edge.
