How is RCC footing quantity calculated?

Measurement of Concrete in Footings: Volume of concrete = L x B x D for Rectangular and Square footing. For Trapezoidal Footing, Volume of Concrete is calculated in two parts. Bottom Rectangular portion is calculated separately and Trapezoidal volume is calculated separately.

How do you calculate concrete in RCC structure?

Calculation of volume of concrete for the column:

  1. Volume of Concrete = 0.6×0.4×3= 0.72m3
  2. Volume of Circular column = πr2 x 3 = 3.14 x 0.252 x3 = 0.58m3
  3. Volume of concrete = 1.2x1x0.1 = 0.12m3 Total volume of concrete required for footing= 0.32+0.12=0.44m3

How many types of combined footings are possible?

A combined footing may be rectangle or trapezoidal in plan. The object is to get uniform pressure distribution under the footing. For this, the C.G of footing area should coincide with the C.G. of combined loads of the two-column.

Details Obtained from Structural Drawing

  1. Length of Footing = X.
  2. The breadth of Footing = Y.
  3. The height of the footing (Thickness) = h.
  4. The diameter of the Main reinforcement bars = d. m
  5. The diameter of Distribution Reinforcement Bars = d. d
  6. The spacing of reinforcement bars = s.
  7. Cover for reinforcement = c.

How is RCC material calculated?

Consider concrete with mix (M15) of proportion 1:2:4 = 7 where, 1 is part of cement, 2 is part of fine aggregates and 4 is part of coarse aggregates of 20mm Size. 7 is the Sum of ratio. We assume the bulk density of Cement as 1440 Kg/m3, Sand = 1450 Kg/m3 and Coarse Aggregates as 1500 Kg/m3.

How do you calculate RCC walls?

  1. quantity calculation of cement for retaining wall. Volume of cement required. 1m3 = 35.3147 cft.
  2. quantity of sand the required for retaining wall. Volume of sand in cft. = (1.5/5.5) ×50.82×35.3147=489.46cft.
  3. quantity of aggregate required for retaining wall. Volume of aggregate in cft. = (3/5.5)×50.82×35.3147 =979 cft.
