Civil Engineering Tips.

There are many activities that should be performed by Civil Engineers at site & in the lab. In This Article we will discuss some important points which every civil engineer must learn & remember. These tips are can also helps to the crack interview. This is the kick start guide if u are joining in the any company as a Civil Engineer.

Civil Engineering Tips

  1. ASTM Abbreviation : American Society for Testing Materials
  2. Grade of the Concrete is denoted as Cement: Sand: Aggregate (Ex M20 Grade : 1:1.5:3)
  3. C/C means Center to Center Distance.
  4. DL means Development Length.
  5. Lapping of the bars not allowed if the dia of bar is more than 36-mm.
  6. For circular column minimum of Six longitudinal bars are used.
  7. The minimum thickness of the slab is 0.125=m
  8. Water pH value less than Six should not be used for the construction purpose.
  9. The concrete Should not be thrown from the height more than One m.
  10. The Compressive strength of the Bricks is 3.5 N /mm2
  11. The initial setting time shall not be less than 30 minutes & the final setting time of the cement is 10hours.
  12. Dead Load means Self weight of the Structure.
  13. Sand having moisture content more than Five % should not be used for the Concrete mix.
  14. DPC means Damp Proof Course. The thickness of the D.P.C should not be less than 2.5-cm.
  15. Cube test is carried out for the each 30-m3 usage of concrete.
  16. RMC : Ready Mix concrete The concrete is made at factory & transported to the site, This type of the concrete is used where there is a lack of space for mixing the concrete & used where the huge amount of the concrete is required for construction.
  17. The height of the floor is usually three m or 10-ft (If the person asks you what’s the height of 12 storied building? Ans: three m x 12-floors = 36-m)
  18. A head mason can work 25-30 m3 in the day.
  19. M-20 grade of the concrete is generally used in the construction of the slab.
  20. Weight of the Bar is calculated using formula D2/162 (D = Dia of the bar in mm)
  21. The No. of the Bricks required for one m3 of Brick masonry are 550 bricks.
  22. Specific gravity of the Cement is 3.16g/cm3; Bricks is two g/cm3;  Sand is 2.65g/cm3 ,
  23. Standard Size of the Brick is 19-cm x 9-cm x 4-cm or 19-cm or 9-cm x 9-cm
  24. Floor area occupied by 50kg of the Cement bag is 0.3m2 & height of 0.18m.
  25. As per IS 456: 2000, Maximum dia of the bar used in the slab should not exceed 1/8th of the total thickness of slab.
  26. IS 456:2000 is Code of Practice for Plain & Reinforced Concrete.
  27. IS 800:2000 is code of Practice for the General steel construction.
  28. The slope or Pitch of the stair should be in between 25 degrees to the 40 degrees.
  29. The rise in stairs is in between the 150-mm to 200-mm.
  30. Tread in staircase is in between the 250-mm to 300-mm.
  31. Hook length should not be less than 9-D (Dia of the Bar)
  32. Unit weight of the P.C.C is 24KN/m3 , R.C.C is 25 KN/m3 , Steel is 7850Kg/m3
  33. The volume of the 50-kg cement bag is 1.3CFT.
  34. Theodolite least count is 20-Secs whereas Compass Least count is 30-mins.
  35. TMT bars : TMT means Thermos Mechanically treated bars.
  36. Cement more than three months old cannot be used for the construction.
  37. The length of the each bar from factory is 12-m.
