Civil engineering has five major parts and of course a lot of Civil Engineering Interview Questions arises from each of them with too much definitions to equations. We are going to present some civil engineering interview questions for the students and for the job seekers.

 

Question-1:What is hydration?

Answer: Hydration is the reaction between cement and water.

Question-2: What is curing of concrete?

Answer: Curing is the application of water to the concrete surface for the proper hydration to occur.

Question-3: What are the methods of curing?

Answer: Generally water is applied by various means. The common methods of curing are:

  • Spraying
  • Wet Covering of surface
  • Ponding
  • Steam Curing
  • Application of curing compounds/admixtures

Question-4: For the quality control of cement what tests are done?

Answer: The tests that are required to check the quality of cement are–

  • Initial and Final Setting time
  • Consistency
  • Tensile strength
  • Soundness

Question-5: What may be the mix proportion for M10 grade concrete?

Answer: Cement: Sand: Aggregate = 1:3:6

Question-6: When the possibility of segregation is much?

Answer: Segregation of concrete may occur if the concrete mix is-

  • If the mix is too wet
  • If the ratio of coarser aggregate is much more thatn the others proportions
  • Coarser grading

Question-7: What happens to ordinary cement after casting?

Answer: Ordinary cement shrinks after drying.

Question-8: With what compounds of cement the hydration takes place?

Answer: Silicates( Tricalcium Silicate and Dicalcium silicate),Tricalcium aluminate,tricalcium alumino ferrite

Question-9: When an aggregate may be called as flaky?

Answer: When the least dimension of the aggregate is less than 60%, Then the aggeregate may call as flaky.

Question-10: Why Vicat’s apparatus is used?

Answer: To determine the Consistency of cement vicats apparatus is used.

Question-11: What are least cover dimensions for different structural member?

Answer:

Footing : Minimum 50mm
column : Minimum 40mm
beam : Minimum 25mm
slab : Minimum 20mm

 

Question-12:  Why I section Beams are preferred?

Answer: I-section is preferred beacuse-

  • it provides large stiffness in lateral direction
  • It has large Moment of inertia.
  • I section has the lowest shape factor.

Question-13: What is shuttering?

Answer: To place the permanent structure a temporary structure of specifird shape and dimension is builtt on the site which is termed as shuttering.

Question-14: What is the difference between deflection and deformation?

Answer: Deflection is a temporary displacement where as deformation is a permanent displacement.

Question-15: What is meant by open-graded aggregates?

Answer: Open graded aggregates are the aggregates that have the coarser size aggregates and as a result the concrete produces more air voids.

Question-16: What is coping?

Answer: Coping is a arrangement of wall to protect the wall from water and environment.

Question-17: What is the specific gravity of cement?

Answer: 3.15(in general)

Question-18: What is development length?

Answer: Development length is an embedded extra length .

Question-19: What is the differences between working stress method and limit state design method?

Answer: Working stress method considers the elasticity of the materials and never  loaded beyond the elastic limit where as limit state design is based on plastic method.

Question-20: What is meant by TMT bar?

Answer: TMT means Thermo Mechanicaly Treated. This bar has higher strength and higher corrosion resistance to the exposed environment
