**Material estimate for round water tank Rcc**

In this illustration we will calculate cement, sand, crushed stone, and of course steel for one tank’s certain water content. Here is today’s post we will discuss how to calculate the material quantity of an RCC round water tank. After reading this article, you will be able to know the material estimate of the RCC round water tank.

## Data for water tank

Here we have two diameters: the outside diameter of the tank and the inside diameter of the tank.

The outer diameter of the water tank = D=5.30 meters

Inner diameter of water tank = D1 = 5 meters

Depth of water tank = 3 meters

RCC at base part = 30 cm = 0.30 meters

Thickness of tank plate water = 10 cm = 0.10 meters

Wall thickness = 15 cm = 0.15 meters

Here we use concrete grade M15 (1:2:4)

Total ratio = 1 + 2 + 4 = 7, Steel Used 2% RCC (Concrete Mass),

## Prize

Tank Outer Diameter (Overall Diameter) = D1 = 5 + 0.15 + 0.15 = 5.3 meters

The inner diameter of the tank = D2 = 5 meters, Here this diameter of the tank does not have 2 wall thicknesses.

Water volume RCC Tank (wall) = V = Working surface RCC x Tank depth

Volume = π /4(D² – D1² ) x 3

Volume = π /4 ( 5.30^2 – 5^ 2 ) x 3,, Building volume RCC = 7.28 m3

,

Slab storage tank = Surface area Plate x slab thickness

,

Volume = π D² / 4 x 0.10 = π /4 x ( 5.3^2 ) x 0.10

Volume = 2,206 m3

Basement volume RCC = Foundation area x foundation depth

Volume = π /4 x D² x 0,30,, product = 3.142 ( 5.3 x 5.3 ) 0.30

Volume = 6.61 m3

The total volume of RCC works = RCC water tank wall volume + water tank floor volume + foundation RCC volume

Total volume of RCC for the water tank = 7.28 + 2.206 + 6.61 = 16 m3

Steel Volume for water tank = 2% of RCC volume

Steel volume = 2/100 x 16 = 0.32 m3

## Now other materials Quantity

Total building volume RCC

Convert wet RCC volume to dry material

Dry volume = wet volume x 1.54 = 16 x 1.54 = 24.64 m3

Cement quantity = cement ratio / Total ratio x dry weight of concrete

Cement weight

Cement weight = 1/7 x dry volume = 1/7 x 24.64 = 3.52 m3

Convert to cement bag = Total weight of cement/bag of cement

Number of bags of cement = 3.52 / 0.0347 = 101.44 of 102 Number of bags

Amount of sand = billion ratios of sand / total bag ratio x dry volume of concrete

Amount of sand = 2 / 7 x dry volume = 2 / 7 x 24.64 = 7.04 m3

Amount of aggregate = ratio of aggregate / Total ratio x dry weight of concrete

Amount of aggregate = 4 / 7 x 24.64 = 14.08 m3

Now Amount of steel we have used is 2 % of RCC

working volume Steel mass = 2 / 100 x 16 = 0.32 m2

Know Steel Weight = 7850 kg/m3

Steel Weight = Density x Steel Weight

Weight of steel = 7850kg/m3 x 0.32 m3 = It takes 2512 kg of steel to build a tank on the water.

Note: We can also use the same formula to know the quantity of material for a rectangular water tank. but their only shape is a rectangle and we need to find the volume of the rectangle only shape change, so to find the amount of material just use the same formulas I discussed in the water tank section above.
