civil engineering basic knowledge



 

Hello Friends , In this video lecture today I will teach you the some basic knowledge for civil engineers which is too much important, Lets get start.

Basic Knowledge for Civil Engineers : 

1: Concrete fall shoul be not more than 1.5 meter

2: Use 4 No’s of steel bar in rectangular column and 6 No’s of bars in circular column.’

3: First class brick should be not absorb water more than 15% his weight.

4: weigh of steel formula = D2/ 162          where D is diameter of steel in mm.

5: Column Hook’s length should be 9D     where D is Diameter of stirrups steel.

6: Building height should not be less than 315 cm = 3.15 meter



7: Splice length should be not use larger than 36 mm dia of steel.

DESIGN MIX:
M10 ( 1 = 3.92 : 5.62)
Cement = 210 Kg/ M 3
20 mm Jelly = 708 Kg/ M 3
12.5 mm Jelly = 472 Kg/ M 3
River sand = 823 Kg/ M 3
weight of water = 185 Kg/ M 3
Concrete density  2398 Kg/M 3
