1. Determine how thick you want the concrete.
  2. Measure the length and width that you’d like to cover.
  3. Multiply the length by the width to determine square footage.
  4. Convert the thickness from inches to feet.
  5. Multiply the thickness in feet by the square footage to determine cubic feet.

What is the formula for calculating concrete quantity requirements?

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.

How do you calculate reinforcement required on a slab?

Steps to calculate the Reinforcement required for Slab:-

  1. Deduct the cover for finding length of bar.
  2. Evaluate the length of the distribution bar.
  3. Calculate the Value of ‘D’ (Depth of slab- Top cover- Bottom cover)
  4. Find out the No. of Bars.
  5. Compute the Total wt of steel required for slab reinforcement.

How is slab design calculation?

Effective depth d= Span /((L/d)Basic x modification factor) For obtaining modification factor, the percentage of steel for slab can be assumed from 0.2 to 0.5%. The effective depth d of two way slabs can also be assumed using cl. 24.1,IS 456 provided short span is <3.5m and loading class is <3.5KN/m.

What is the best way to estimate the amount of concrete needed for a project?

Calculate the Project Volume

Multiply the area by the depth to arrive at volume. Example: 100 square feet of area multiplied by 0.5-foot depth is 50 cubic feet. So, to fill the coop’s form, you will need 50 cubic feet of wet, mixed concrete.

How do I calculate building quantities?

To calculate the quantities of materials, you need to multiply the total centre line length with breadth and depth of the construction. The centre line length will be reduced by half of breadth of every junction where the main wall is joined with the cross walls, partitions or verandah.

How many cubic meters of concrete do I need?

For a wall made of concrete the calculation is practically the same: height(ft) x width(ft) x length(ft). For example, to calculate the volume in cubic meters for a wall with a height of 2m, width of 20cm and length of 4m, you need to multiply 2 x 0.2 x 4, which equals 1.6 m3 (cubic meters).

What is minimum reinforcement in slab?

Minimum reinforcement is 0.12% for HYSD bars and 0.15% for mild steel bars. The diameter of bar generally used in slabs are: 6 mm, 8 mm, 10 mm, 12mm and 16mm. The maximum diameter of bar used in slab should not exceed 1/8 of the total thickness of slab.

How do you calculate reinforcement?

Method-2 : Reinforcement Estimation (Accurate Method):

  1. Calculation:
  2. Bar 1:
  3. Cutting Length = 4380 mm.
  4. Bar 2:
  5. Cutting Length = (2×200) + (4380) – (2 x 20 x 2) = 4700 mm.
  6. Bar 3:
  7. Cutting Length:
  8. No. of Stirrups: (4000/180) + 1 = 23.22 = 24.

How much steel is required for slab?

RCC Slab :

According to my calculation Steel is required for the RCC, the slab is ≈ 80 kg/m3. The total quantity of steel needed for 1 sq ft (0.0118 cubic meter) RCC slab is equal to = 80 × 0.0118 = 0.944 Kg. This means, 0.944 Kg of steel is needed per sq ft of 5-inch thick RCC slab.
