Civil Engineering Basic Knowledge
Cement's initial setting time should be 30 min(Minimum) and 90 min(maximum).
Final setting time of cement should be=10 hours
What type of test should perform for a road's improved subgrade sand filling:
1.FM of fine aggregates
2.California bearing ratio
3.Dynamic cone penetration test
4.MDD of fine aggregate
5.Field Dry Density.
What type of test should perform for earth filling in Embankment with specified soil:
1.Plasticity index.
What type of test should perform for Concrete Work:
1.Setting time of cement
2.Compressive strength of cement
3.Gradation of Coarse aggregates.
4.FM of fine aggregates.
5.Water absorption of coarse aggregates
6.Loss angels abrasion test
7.Concrete cylinder casting & testing
What type of test should perform for M.S High strength deform bar
1.Tensile strength,Elongation and unit wt.
What type of test should be perform for Brick work:
1.Setting time of cement
2.Compressive strength of cement
3.FM of fine aggregates
4.Compressive strength of brick
5.Water absorption of brick
6.Efflorescence of brick.
Local sand FM limit should be 0.5 to 0.8
Toak sand FM limit should be 1.2 to 1.8
Coarse sand or shylhet sand FM should be 2.5
At improved sub grade 0.5 to 0.8 FM sand should be used.
1.Ms Flat bar weight determine equation=0.00785A
2.Brick require for 1 square meter one brick flat soling=32nos.
3.Brick require for 1 square meter one layer herring bone bond soling=52nos.
4.Cement require for 9.3 square meter neat cement finishing=1/2bag or 25kg
5.A head mason can work 25-30 cum brick work in a day.
1.Lintel thickness should be 15cm.
2.Parapet wall height should be 1 meter.
3.Window height should be 120cm.
4.D.P.C thickness should be 2.5cm
5.Plinth height should be 45cm.
6.Measurement of riser should be 15cm.
7.Building height should be 315 cm
8.plaster thickness at ceiling should be 6mm.
Q1:1 cum cement=how much bag?
answer:30 bags.
q2:1cum =how much brick?
answer=300 nos
