# How to Calculate The Total Tons of Granite for a Volume of Concrete

I previously discussed How to Calculate the Total Bags of Cement and Tones of Sand for a Particular Volume of Concrete, today, I will be explaining How to Calculate The Total Tons of Granite for a Volume of Concrete.

As an Engineer, Quantity Surveyor and Site Manager on Construction Site, you must know how to calculate this in other to prevent wastage of Material and for full accountability of Total Tons of Granite used for a Particular Volume of Concrete.

The calculations below is all about 1:2:4 mix ratio of Concrete.

TOTAL RATIO = 1+2+4 = 7
Since we are dealing with Granite, we have 4/7 = 0.571
For 1m³ of Granite = 1m³ * 0.571
= 0.571m³

Density =  Mass/Volume

Density of Granite = 2750kg/m³

Let’s consider 1tons of Granite = 1000kg

2750 = 1000/Volume

Volume = 0.364m³

0.364m³ of Granite = 1 ton of Granite
0.571m³ of Granite = X tons of Granite

X = 1.57 tons.

Now for 1:2:4 mix ratio, the Amount of Granite require to mix 1m³ of concrete
= 1.57 tons.

Assuming you are to calculate the amount of Granite require for 0.55m³ of concrete

1m³ of concrete = 1.57 tons of Granite

0.55m³ of concrete = X tons of Granite

X = 0.86 tons of Granite

This means 0.86 tons of Granite will mix 0.55m³ of concrete using 1 : 2 : 4 mix Ratio
