50 mm J bolt : 751 No’s / 52 Kg

40 mm J bolt : 883 No’s / 54 Kg

2” nails : 385 No’s / Kg

3” nails : 118 No’s / Kg

4" nails : 72 No’s / Kg

Binding wire : 170 rings /Kg

*SIMPLEX FORMULA:-

U = (N /L) x {(W x H) / (1 + S)} x Sq.rt {(L/50)}

U = Ultimate load in tones

N = Number of blows

L = Pile length in feets

W = Weight of hammer in tones

H = Height of fall in feet.

S = Set for 1 blows in Inch

Safe load = (ultimate load/ 2.5)

Factor of safety = 2.5

10 blows = below 10 MM

*Thread couplers:- (For Column lapping)

1. 0-10mm = +7%
2. 10-16mm = + 5%
3. 16 and above = + 3%

*TOLERANCE FOR CUTTING

*TEST FOR SILT & CLAY:-

1. Take 200 ml measuring cylinder fill sand up to 100ml mark.
2. Add 150ml of water and shake well.
3. Allow it to settle for 3 hrs.
4. Measure the total height and height of clay.
5. Calculate the clay and silt in total sand.
6. Clay and Silt should not exceed 3% by weight (or) 8-10% by volume.
7. For crushed sand Clay and Silt should not exceed 15% by weight.

*ORGANIC IMPURITIES:-

1. Don’t dried the specimen before testing.
2.  Take 250 ml measuring cylinder.
3. Add 75 ml of water with 3% of Sodium Hydroxide. Fill sand layer to 125 ml
4. Make the volume up to 200ml by adding more of sodium hydroxide solution.
5. Shake well allow it to stand for 24 hrs.
6. If the solution becomes darker than straw yellow colour then the sand has to be
7. Tested for further by casing mortar cubes for 7 & 28 days is not less than 95%.

8. If the solution is lighter or just straw yellow colour the sand can be used for

concreting without any further test.

*QUANTITIES REQUIRED:-

Plastering (CM 1:3) = 1.50 bags / 10 m2.

*TRAPEZOIDAL FOOTING FORMULA:- 

Volume, 

V = (L x B x D) = H/3{A1 + A2 + sq.rt(A1+A2)}

Where A1 = L x B

A2 = l x b B

H = D-d (Overall depth of footing – depth of

 Rectangular footing.
