For cracking Civil Engineering interviews, one needs proper preparation that involves study of various topics. If you have with you basic civil interview questions and answers, then it will make your job that much easier. That’s the reason we will be sharing with you, some of the favourite Civil interview questions, with answers to them.
Basic Civil interview questions and answers for freshers:
Elaborate on why concrete barriers possess curved surface profiles
Vehicles are contained inside their path being traveled, with the help of safety fencings of concrete, in order to lessen the odds of rebounding into the streets prompting more risks. As far as the normal fencings go, they tend to give away in case of vehicle crashes in order to absorb the maximum energy consequently decreasing the impact on the vehicles. However, taking into consideration the concrete barriers, their purpose isn’t to ingest the energy of vehicles colliding with the barrier, but to retain them. They come with a curbed design in order to permit the vehicles that hit them to somewhat go up on the obstruction however not turn upside down. They likewise keep the vehicle away from again getting back on the road doing rebounds. This aides in tremendously decreasing the odds of other vehicle risks.
Explain the role of slip joints in case of block work seawalls
Joints which are shaped up to the toe level from the cope level of seawalls via a total vertical plane are termed as slip joints. The purpose of such joints is to deal with the differential settlements within the seawalls adjacent panels. Vertical motion is facilitated by the aggregates within the half-rounds channels, in case of the slip joints. Such vertical movements are prompted by differential settlements. This allows the interlocking of the adjoining seawall panels to connect the panels in a single unit against the earth pressure ( lateral ) which is applied on the seawalls.
List out the various steps involved in the process of concreting
Significant steps involved in the process of concreting are as follows:
– Placing and transporting of concrete
This happens to be one of the fundamental Civil interview questions for freshers. You might be asked to explain each of these steps as well. Therefore, prepare properly.
When is it appropriate to use pot bearings instead of elastomeric bearings?
Pot bearings are favored over elastomeric bearings in circumstances where the odds of high vertical loads is more in combination of huge angle of rotations. dependably require An extensive bearing surface is required for Elastomeric bearings, such that a compression is sustained between the contact surfaces in the middle of the bearings and the piers. This isn’t feasible to maintain under high load and rotational conditions. Likewise, the use of elastomeric bearings prompts the non-uniform dispersion of stress on the piers. The outcome is some profoundly induced stresses to be focused at the piers thus harming them. Because of the above reasons, pot bearings are favored over the elastomeric bearings in such situations.
Why shouldn’t curing be carried out by ponding and polythene sheets?
The basic purpose of curing is to lessen the loss of heat of concrete that is crisply placed to the surroundings and to bring down the temperature gradient across the cross-section of the concrete. Ponding isn’t favored for curing as this technique of thermal curing is largely influenced by the cool breezes. Notwithstanding that, in ponding huge amounts of water is utilized and must be disposed off from the construction sites. Creating an airtight condition surrounding the concrete surface is possible through the use of Polythene sheets, thus lessening the odds of evaporation over freshly built concrete surfaces. The use of polythene can be a disadvantage as it can be blown away by winds easily, and furthermore the water loss due to self-desiccation, can’t be replenished.
