Tutorial: How Many WheelBarrows Of Cement, Sand And Granite Are In 1m³ Of Concrete


Today On Building Contractor Secrets i would love to make it easy for those on site thinking about How many wheelbarrows of sand, granite and bags of cement makes up 1 cubic meter (1m³) of Concrete. This is going to be very useful because i am also going to let you know the value of one Head Pan. This is very important because i know that here in Nigeria where i am from, many construction sites cannot afford the cost of renting a Mixer, thus, they make use of manual labor which means laborers will be made to carry head pans or wheel barrows filled with sand in order to achieve the day's task.

So Lets Begin...!

What is the Volume of a head pan?

The Volume of a head pan is 0.017m³

How Many Head pans Makes one wheel barrow?

4 head pan loads of sand makes a wheelbarrow...

Now lets assume your Volume of concrete is 1m³

Lets also assume you're using a mix ratio of 1:2:4

Wait!

What Does 1:2:4 Mean in Concrete?

Its simply means for every bag of cement, there should be 4 head pans of sand and 8 head pans of granite.

How Many Head Pans Of Cement Makes 1 Bag?

We have exactly 2 Head Pans of Cement In One Bag Of Cement

How Do I Calculate The Volume Of A Beam, Foundation Or Slab?
 If You know the length, breadth and Depth, Multiply all 3 dimensions.
That's it.

Now, Total Volume = 1m³

The Volume of cement in 1m³ Will be

1/7 x 1 = 0.14m³. Now Divide this by The Volume of a bag of cement (0.035m³) we will have 4 Bags

For Sand

2/7 x 1 = 0.29m³. Diving by the volume of 1 head pan (0.0175) we will have 16 head pans. But 4 Head Pans Equals 1 Wheelbarrow. So 16/4 = 4 Wheelbarrows of sand

For Granite

4/7 x 1 = 0.57m³. Dividing by the 0.0175 (Volume of a head pan) we will have 32.8 head pans which is equal to 8 wheel barrows when divided by 4

I will Present these in a tabular form...
