How Many Bags Of Concrete In A Yard?

How many bags of concrete do i need? Let me clear first, here we are discussing about ready mix concrete mix bags. Traditionally, concrete is made by mixing cement, sand, and aggregate together to make the homogeneous dry mix. Then water is added to the mix to make concrete for different work.

But now people don’t want to order each material separately and then mix them and use them for work. The concrete is now available in dry mix products which are filled in bags like cement bags. So, the buyer only needs to add sufficient water to make wet concrete.

There is a various brand that supplies this dry mix concrete product such as Quikrete, Sakrete, and other brands in the USA.

How many bags of concrete in yards are required to depend on the weight or size of the concrete dry mix bag you have ordered from the company.

Bag Size	Yield
40 lb. (18.1 kg)	0.30 cu. ft. (.008 cu. m)
45 lb. (20.4 kg)	0.34 cu. ft. (.01 cu. m)
60 lb. (27.2 kg)	0.45 cu. ft. (.012 cu. m)
80 lb. (36.2 kg)	0.60 cu ft. (.016 cu. m)
90 lb. (40.8 kg)	0.68 cu. ft. (.02 cu. m)

Let’s understand with an example,

1. How Many 40lb Bags Of Concrete In A Yard?

If you ordered a 40lb (18.1 kg) weight bag of concrete which yields work approximately 0.30 cu. ft.

So, we know that 3 ft = 1 yard

Therefore, 3 ft x 3 ft x 3 ft = 27 cu. ft and 1 yard x 1 yard x 1 yard = 1 cu. Yard

It means 27 cu. ft = 1 cu. yard

So, you get how many bags of concrete in a yard, you have to divide the 27 cu. ft. by 0.60.

27 /0.60 = 90 bags

So, you required 90 bags of concrete in a yard of work.

2. How Many 45lb Bags Of Concrete In A Yard?

If you ordered a 45lb (20.4 kg) weight bag of concrete which yield work approximately 0.34 cu. ft.

So, we know that 3 ft = 1 yard

Therefore, 3 ft x 3 ft x 3 ft = 27 cu. ft and 1 yard x 1 yard x 1 yard = 1 cu. Yard

It means 27 cu. ft = 1 cu. yard

So, you get how many bags of concrete in a yard, you have to divide the 27 cu. ft. by 0.34.

27 /0.34 = 80 bags

So, you required 80 bags of concrete in a yard of work.

3. How Many 60lb Bags Of Concrete In A Yard?

If you ordered a 60lb (27.2 kg) weight bag of concrete which yield work approximately 0.45 cu. ft.

So, we know that 3 ft = 1 yard

Therefore, 3 ft x 3 ft x 3 ft = 27 cu. ft and 1 yard x 1 yard x 1 yard = 1 cu. Yard

It means 27 cu. ft = 1 cu. yard

So, you get how many bags of concrete in a yard, you have to divide the 27 cu. ft. by 0.45.

27 /0.45 = 60 bags

So, you required 60 bags of concrete in a yard of work.

4. How Many 80lb Bags of Concrete In A Yard

If you ordered an 80lb (36.2 kg) weight bag of concrete which yield work approximately 0.60 cu. ft.

So, we know that 3 ft = 1 yard

Therefore, 3 ft x 3 ft x 3 ft = 27 cu. ft and 1 yard x 1 yard x 1 yard = 1 cu. Yard

It means 27 cu. ft = 1 cu. yard

So, you get how many bags of concrete in a yard, you have to divide the 27 cu. ft. by 0.60.

27 /0.60 = 45 bags

So, you required 45 bags of concrete in a yard of work.

5. How Many 90lb Bags Of Concrete In A Yard?

If you ordered a 90lb (48.8 kg) weight bag of concrete which yield work approximately 0.68 cu. ft.

So, we know that 3 ft = 1 yard

Therefore, 3 ft x 3 ft x 3 ft = 27 cu. ft and 1 yard x 1 yard x 1 yard = 1 cu. Yard

It means 27 cu. ft = 1 cu. yard

So, you get how many bags of concrete in a yard, you have to divide the 27 cu. ft. by 0.68.

27 /0.68 = 40 bags

So, you required 40 bags of concrete in a yard of work.

How Much Water Will I Need Per Bag?

The amount of water to add per bag depends on the size and weight bag supplied by the company.

Always Check Company recommended water amount per bag of concrete while making the mix.

The following are various sizes of concrete bags and recommended water content in them.

Bag Size	Water
40 lb. (18.1 kg)	1.8 Liter
45 lb. (20.4 kg)	2.1 Liter
60 lb. (27.2 kg)	2.8 Liter
80 lb. (36.2 kg)	3.7 Liter
90 lb. (40.8 kg)	4.2 Liter

How Many Square Feet Are In A Yard Of Concrete?

The square feet area cover by the yard of the concrete bag will depend on the thickness of the slab.

For example,

If we have 60lb of a bag of concrete and we know that it will give us 0.45 cu ft of work.

And, the thickness of slab is 2” (2/12 = 0.17 ft, Because 12” = 1 ft)

Convert cu ft to sq ft,

Sq ft = cu ft / thickness (depth)

= 0.45/0.17 = 2.64 sq ft

So, an 80lb bag of concrete can cover an area of 2.64 sq ft area.

Similarly, another size of a bag of concrete and their covered area is given in the below table,

1. For 2” Thickness of Slab

Bag Size	Sq ft Area Work
40 lb. (0.30 cu. ft)	1.76 sq ft
45 lb. (0.34 cu. ft)	2.0 sq ft
60 lb. (0.45 cu. ft)	2.64 sq ft
80 lb. (0.60 cu. ft)	3.52 sq ft
90 lb. (0.68 cu. ft)	4.0 sq ft

2. For 4” Thickness of Slab

Bag Size	Sq ft Area Work
40 lb. (0.30 cu. ft)	0.90 sq ft
45 lb. (0.34 cu. ft)	1.02 sq ft
60 lb. (0.45 cu. ft)	1.35 sq ft
80 lb. (0.60 cu. ft)	1.80 sq ft
90 lb. (0.68 cu. ft)	2.04 sq ft

3. For 6” Thickness of Slab

Bag Size	Sq ft Area Work
40 lb. (0.30 cu. ft)	0.60 sq ft
45 lb. (0.34 cu. ft)	0.68 sq ft
60 lb. (0.45 cu. ft)	0.90 sq ft
80 lb. (0.60 cu. ft)	1.20 sq ft
90 lb. (0.68 cu. ft)	1.36 sq ft
