How Many Cement, Sand and Steel Required For 10×10 Feet Room?

44 bags of 50 kg cement and 104.2 cft sand is required for 10×10 feet room by assuming 11 feet height of room with some other requirements and considerations. Read complete to understand the concept.

How Many Cement, Sand and Steel Required For 10×10 Feet Room - 100 Square Feet Room

Calculation For Cement, Sand and Steel Required For 10×10 Feet Room

To calculate the quantity of cement, sand and steel required for 10×10 feet room (1000 sq. feet room), we have some considerations and requirements in the room.

Requirements of the Room

We have the following requirements for 10×10 feet room:
  • Four sided walls
  • One gate
  • One window
  • RCC Roof

Considerations of the Room

We are considering the following for 10×10 feet room.
  • The wall size is 10 feet height × 10 feet width
  • One window of size 4 feet × 3 feet
  • One gate of size 7 feet × 3 feet
  • Indian standard brick size is 190×90×90 mm
  • Mortar thickness 12 mm (cement:sand ratio is 1:4)
  • Roof slab thickness is 5 inch (cement:sand:coarse aggregate ratio is 1:1.5:3)
  • Wall thickness is 4 inch
  • Column size is 10 inch × 12 inch
  • Beam size is 10 inch × 12 inch
  • Lintel Size 4 inch × 5 inch
  • Clear Floor Height is 11 feet

Brick Work Calculation

Face Area of Brick Work
= Face Area of Wall - Face Area of Gate and Windows
= (No. of Walls × Length × Height) - (Length × Width of Gate) - (Length × Width of Window)
= (4 × 10 × 10 × 4/12) - (7 × 3 × 4/12) - (4 × 3 × 4/12) 
= 122.33 cft

Volume of One Brick with 12 mm Mortar
= 202 × 102 × 102 = 2101608 mm³ or 0.07422 Cubic Feet

Total Number of Bricks in 10×10 Feet Room
= (Volume of Brick Work/Volume of One Brick With Mortar)
= (122.33/0.07422) = 1648 Bricks
Considering waste factor (10% extra) = 1648 + 10% of 1648 = 1648 = 1812.8, Say 1813 Bricks.

Cement and Sand Calculation in Mortar

  • Volume of Brick Work = 122.33 Cubic Feet
  • Volume of One Brick Without Mortar is 0.05438 Cubic Feet
  • Number of Bricks in 12×12 Feet Room is (122.33/0.05438) = 1813
  • Mortar Thickness is 12 mm, Mortar Ratio is 1:4
  • Shrinkage Factor is 1.3 (i.e. 30% extra of dry volume) and 
  • Unit Weight of Cement is 1440 kg/m³
  • Unit Weight of Sand is 1600 kg/m³

Volume of Dry Mortar
= Total Volume of Brick Work - Total Volume of Bricks Without Mortar
= 122.33 - 1648 × 0.05438 = 32.712 Cubic Feet

Total Volume of Dry Mortar
= 1.3 × Volume of Dry Mortar
= 1.3 × 32.712 = 42.526 cft or 1.204 m³

Total Mortar Ratio (1:4) = 1+4 = 5

Total Volume of Cement
= (Cement Ratio/Total Mortar Ratio) x Total Dry Volume of Mortar x Unit Weight of Cement
= (1/5) × 1.204 × 1440 kg/m³ = 295 kg or 6 Bags of Cement (Each 50 kg).

Total Volume of Sand
= (Sand Ratio/Total Mortar Ratio) × Total Dry Volume of Mortar × Unit Weight of Sand
= (4/5) × 1.204 × 1600 kg/m³ = 1541 kg or 0.963 m³ or 34 cft.

Calculation For RCC Work

Volume of RCC of Column
= No. of Column × (Total Height of Column × Cross-Section of Column)
= 4 [(11 Feet Height + 5 Feet Below Ground Level) × (10 inch/12) × (12 inch/12)]
53.3 cft

Volume of RCC of Beam (Plinth Beam and Floor Beam)
= 2 × [Total Length of Beam × Cross-Section of Beam)]
= 2 × [(4 Sides × 10 feet) × (10 inch/12) × (12 inch/12)]
66.67 cft

Volume of RCC of Lintel
= (4 Sides × 10 feet) × (4 inch/12) × (5 inch/12)
= 5.56 cft

Volume of RCC of Roof Slab
= Area of Roof Slab × Thickness of Roof Slab
= 10 Feet × 10 Feet × (5 inch/12)
41.67 cft

Total Volume of RCC Work = 53.3+66.67+5.56+41.67 = 167.2 cft (Wet Concrete).

Calculation of Cement, Sand and Coarse Aggregate

Ratio of Concrete (M20) = 1:1.5:3 (cement:sand:coarse aggregate)
Shrinkage Factor = 1.54 (54 % extra for dry volume)
Total Concrete Ratio (1:1.5:3) = 1+1.5+3 = 5.5
Total Volume of Dry Concrete = 1.54 × 167.2 cft = 257.5 cft 

Volume of Cement in RCC Work
= (Ratio of Cement/ Total Ratio of Concrete) × Total Volume of Dry Concrete
= (1/5.5) × 257.5 = 46.8 cft or 1.325 m³ or 1908 kg or 38 Bags of 50 kg Cement
 
Volume of Sand (Fine Aggregate) in RCC Work
= (Ratio of Sand/ Total Ratio of Concrete) × Total Volume of Dry Concrete
= (1.5/5.5) × 257.5 = 70.2 cft

Volume of Coarse Aggregate in RCC Work
= (Ratio of Aggregate/ Total Ratio of Concrete) × Total Volume of Dry Concrete
= (3/5.5) × 257.5 = 140.5 cft

Weight of Steel in RCC Work
Considering volume of Steel is 2% of total volume of concrete.
= 167.2×2 /100 = 3.344 cft or 0.095 m³
Density of Steel is 7850 kg/m³ 
Weight of Steel = 7850 × 0.095 = 746 kg

Finlay,
Total Cement Required = 295 kg for brick work + 1908 kg for rcc work = 2203 kg or 44 Bag Cement (50 kg each bag)
Total Sand Required = 34 cft for brick work + 70.2 cft for  rcc work = 104.2 cft
Total Aggregate Required = 140.5 cft
Total Weight of Steel Required = 746 kg

Summary

Bags of Cement in 10×10 Feet Room is 44 Nos. (Each 50 kg).
Volume of Sand in 10×10 Feet Room is 104.2 cft.
Volume of Aggregate in 10×10 Feet Room is 140.5 cft.
Weight of Steel in 10×10 Feet Room is 4 kg 
Number of Bricks in 10×10 Feet Room is 1813 Nos.

Note: This quantity just for reference and it is based on above assumptions and it may vary depending upon material type and other design changes.
