Hello Friends, In this video lecture I will discuss about some useful information for civil engineers, which is too much important to learn. so Let’s get start.

**Some Useful Information for Civil Engineers:**

1: Lapping length of tension member is 40D where D is dia of steel which are using in tension member.

2: Lapping length of compression member is 50D where D is dia of steel which are using in compression member.

3: Concrete should be not fall more than 1.5 meter

4: Weight of one meter steel formula is D2 / 162 so it will give us the weight in kg/m but D should be in mm

5: Density of cement is 1440kg/ cu.m

6: Volume of One bag cement is 0.0347 cu.m which is 50kg

7: Volume of one bag cement is 1.25 cft which is 50kg

8: Maximum water absorption by bricks – 15%

9: Compressive strength of bricks is 3.5 N/mm2

10: Density Of Bricks is from 1600 to1920 Kg/m3
