How to Calculate Cubic Meter of Concrete?

Cubic meter is nothing but the SI unit of volume. For the construction of buildings, you need to know how to calculate cubic meter of concrete so that you can buy building materials accordingly and avoid buying less or excess materials. How to calculate cubic meter of concrete? During construction, you need to have a proper mixture of the materials and need to know how much concrete is to be used. To calculate the cubic meter of concrete, all you need to do is multiply the length, breadth, and depth of the area you are planning to fill. The formula is Length* Breadth* Depth=Cubic meter. The measurements can be in Meter, Centimeter, Inch, or even Feet. How to calculate cost of concrete per cubic meter? For M20 concrete grade, you will need a ratio of 1: 1.5: 3 of cement, sand, and coarse aggregates respectively. Materials(kg) required Dry volume = Wet Volume X 1.52 Volume of Cement = (arid volume X Cement ratio)/ Sum total of ratio Volume of Cement = (1 X 1.52)/(1+1.5+3) = 1. 52/5.5 = 0.28m3 Amount of the cement = 0.28 X 1500 = 420 kg. Volume of Sand = (1.5 X 1.54)/(1+1.5+3) = 2.31/5.5 = 0.42m3 Amount of the Sand = 0.42 X 1700 = 714 kg. Volume of Coarse Aggregate= (3 X 1.54)/(1+1.5+3) = 4.62/5.5 = 0.84m3 Amount of the Coarse Aggregate = 0.84 X 1650 = 1386 kg. Cost of concrete per cubic meter Cost of cement for 1 m3 = Bags required = 420/50 =8.4 Bags If a bag of cement costs Rs: 330 = 8.4 X 330 = Rs 2772 Cost of sand for 1 m3 = If Cost of 1 m3 of sand is Rs: 1200 = 0.42 X 1200 =Rs 504 Price of coarse aggregate for 1 m3 = If Cost of 1m3 of coarse aggregate is as Rs.1500 = 0.84 X 1500 = 1260 Rs So, total money required for 1m3 of M – 20 concrete is =Price of cement + sand + coarse aggregate = 2772 + 504 + 1260 = 4536 Rs. Rs 4500 (approx) Get free consultation from NoBroker interior design services and know all the details. We hope you now know how to calculate cubic meter of concrete and can estimate how much money you are going to need to complete your desired construction.

The amount of concrete you mix per m3 depends on the strength requirements of the job. You will need approximately one part water to five parts cement by weight. For example, if you need to mix 50kg of cement, you will need approximately 10 liters of water. you can easily calculate the amount of concrete using our online concrete calculator tool.

As a contractor, I can very clearly tell you that it is very important to know the correct ratio of mixing concrete with cement and sand if you are building a house. If you want to know how to calculate concrete quantity in m3, you can continue reading my answer. One thing I can tell you for sure is that cement sand and aggregates for concrete need to be mixed in the proportion of 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25). Let me tell you more about it.

How to calculate m3 concrete?

For 1 cubic meter of concrete you will need:

Cement: 7.29*50= 364.5kg

Sand: 1.5*364.5=546.75kg

Coarse aggregate: 3*364.5=1093.5kg

Factors that affect the cost of concrete

Apart from knowing how to measure concrete in meters, you should also know the factors that affect it. The cost of concrete will not be the same for everyone since it depends on several factors like:

• Which cement you are using 

• What proportion of concrete you are trying to make

• How much the laborers charge in that specific area

• The location and ground condition

• Time required( less time=more charge; more time=less charge)

I hope now you understand how to calculate concrete in m3.

When working on building projects like constructing roads, walls, or foundations, calculating the cubic meter of concrete is crucial. But, the major question is how to calculate volume of concrete in m3. You must adhere to a straightforward formula which is Length x Width x Height in order to determine the exact amount of concrete required. 

How to calculate concrete quantity in m3?

• As Survi mentioned, first, you need to measure the dimensions of the area you want to fill with concrete, such as length, width, and height. Make sure you measure in meters for accurate results. Next, multiply these dimensions together to get the volume in cubic meters. If you're dealing with irregular shapes, break them down into simpler shapes and calculate their volume separately, then add them together.

• The length, width, and height of the space you intend to fill with concrete must first be measured. 

• For precise results, be sure you measure in meters. 

• The volume in cubic meters is then obtained by multiplying these dimensions collectively.

Survi has explained the calculation of 1 cubic meter of concrete really well. However, I have mentioned different formulas for various concrete forms below:

Slab Type	Concrete Cubic Meter Formula
Square	Width x Length x Depth
Round	Depth x Pi x (Radius)^2
Wall	Thickness x Length x Height
Footer	Width x Length x Depth

You should note that to achieve exact outcomes, always use the meters as units of measurement while calculating. Your building projects will be efficient and economical if you use the above method to calculate the cubic meter of concrete precisely. I hope you got an idea of how to measure concrete in cubic meters.
