Minimum diameter of bars in Dowel bars. = 12mm.
Max & bars in Slab = 1x thickness of 8 Slab
Maximum chair Spacing = 1m
Dimensional tolerance of Cube = 2mm.
Max water absorption of first Class brick = 15% of its day wt
Initial Setting time of cement = 30min.
Final Setting time = 10 Hours = 600 minutes.
Ordinary Portland Cement.
DPR: Detailed project Report.
1 Gallon 3.78 liters.
1 yard = 3 feet
weight of Steel = D²/162.25 kg/m
weight of Steel = D²/ 533 kg/ft
The slope of the Staircase = 25°-40°
Size of Concrete testing cube = 150mm x 150mm x 150 mm.
The concrete cube is filled into 3 layers.
Slump Cone is filled in 4 Layers.
Minimum thickness of Shear wall = 150mm.
Max. thickness of Shearwall = 400mm.
Universal testing machine. is used for the Compression test of Concrete & tensile test of Steel Reinforcement.
Minimum Curing period.
1 To 7 days → Normal weather conditions.
2 to 10 days. → Day & hot weather conditions.
Minimum percentage of Steel in column = 0·8% of Gross area.
Max %age of Steel in column = 6% of Gross area.
Lapping is not allowed in the bars of Diameter 36mm or more → Welding is preferred.

Unit Weight

RCC = 25 KN/3 = 25000 N/m3

PCC = 24kN/m³ = 24,000 N/m³.

Steel = 7850 kg/m3.

Minimum no. of bars

For Square Column. or Rectangular -> = 4 bass.

For Circular Column = 6 bass.

Bar Bending Schedule For Column With Footing

Nominal Cover Footing = 50mm

i-Slab = 20mm.

ii-Beam 25mm.

iii-Column = 40mm.

How to Calculate the Bar Bending Schedule of The Footing

The angle of the staircase is 225° – 40%

Riser = 150mm – 200mm.

Tread = 250 mm – 300mm.
