Civil Engineering Interview Questions For Freshers:
15 Civil Engineering Questions and Answers
1) What’s the difference between one-way slab and two-way slab?
Ans) One way slab: Ratio of Longer Span / Shorter span > 2
Two way slab: Ratio of Longer span/ shorter span <= 2
2) What are the Nominal Concrete Mix proportions for different grades?
Ans) M5 - 1:5:10
M7.5 - 1:4:8
M10 - 1:3:6
M15 - 1:2:4
M20 - 1:1.5:3
M25 - 1:1:2
3) What Is Workability Of Concrete?
Ans) Concrete is said to be workable when it is easily placed and compacted homogeneously i.e without bleeding or Segregation.
4) What are different types of Slumps to be Considered in Workability Of Concrete ?
*True Slump
* Shear Slump
* Collapse Slump
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
* Collapse Slump
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 effecting 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.
5) What is Slump in Civil Engineering ?
Ans) Slump test is performed to empirically measure the workability of fresh concrete. It is used to measure the consistency of the concrete.
6) What is Compressive strength of first class and second class brick ?
Ans) First Class Brick - 105 Kg/cm2
Second Class Brick - 70 Kg/cm2
7) How many groups are there in IS codes for Civil Engineering?
Ans) There are 41 groups or categories of IS codes available for Civil Engineering.
8) What is Initial and Final Setting Time of cement ?
Ans) Initial Setting Time - 30Mins
Final Setting Time - 10Hrs
9) What is bleeding in Concrete ?
Ans) Bleeding is form of segregation where water comes out of surface of concrete.
10) How many types of compass are used in surveying ?
Ans) The two compass types used in surveying are Prismatic Compass and Surveyor’s Compass. Prismatic Compass is most commonly used one for surveying.
11) What is the Unit Weight Of Concrete ?
Ans) For PCC - 24 Kn/m3
For RCC - 25 Kn/m3
12) What is the unit weight of Steel ?
Ans) Unit Weight of steel is 78.5 Kn/m3
13) What is general weight of steel bar used in Reinforcement ?
Ans) Weight of Steel Bar = D Square / 162 where D is dia of steel bar
14) What is minimum cover provide in RCC Members ?
Ans) Footing = 50 mm
Column = 40 mm
Beam = 25 mm
Slab = 20 mm
15) Function and Full Form Of TMT ?
Ans) TMT Stands for “Thermo Mechanically Treated” Bars.
These bars have high strength and high corrossive resistance that normal bars.
