How much concrete is in a cubic yard | how much is a cubic yd of concrete | how to calculate concrete in cubic yards.
Concrete is the mixture of Portland cement, sand (fine aggregates), gravel (coarse aggregate), water and different types of approved admixture or ingredients. Concrete is prepared in different varieties, it is available in dry condition in premixed bagged concrete, or ready mix concrete which are prepared in batching plant by mixture machine, or it is manually mix at construction site by taking required ratio of cement, sand, gravel and water.
What is a cubic yard of concrete?, A cubic yard of concrete is unit of measurement of volume, which is visually represented by 3 feet long by 3 feet wide by 3 feet depth, so, 1 cubic yard of concrete is 3’×3’× 3′ = 27 cubic feet, so 1 cubic yard of concrete is equivalent to 27 cubic feet.
Modern era demanding the concreting work for various purpose such as casting of different slab, for making patio, ramps, footing, filling holes, holes post, different types of column, beam, shelter house, street, pathway, roadway, house construction, bridge formation, making heavy dams, canals and channels and in different types of construction industry.
In United States concrete are sold in bag concrete for small projects, popularly known as premix bag such as larger size of 90lb and 80 pound, medium size of 60 pound and smaller size of 40 and 50 pound. A 50 pound concrete is fast setting concrete. Premixed concrete bags are used for driveways, patios, foundations walls and footings, curbs, stairs and structural applications and also great for setting footings, pouring slabs and anchoring posts and poles.
In US, generally for larger projects, Ready mixed concrete is calculated by the yards, which is is good for making Large patios, driveways, pool decks and more, foundation slabs for a house, parking lots or commercial sidewalks.
Larger jobs such as driveways, roadway, and larger slab are simple easier to complete when ordering concrete by the cubic yards, buying by the truckload is typically about total of 10 cubic yards, though this can very from company to company. If you are ordering less than truckload of concrete can as expect to pay extra per cubic yard.
Rather than trying to mix a concrete bag after bag by hand. But for smaller jobs, like a walkway, modest patio or footings, you should calculate the number of concrete bags instead. Bagged concrete is ideal for Pouring small slabs for sidewalks or patios, setting posts for fences or mailboxes, making repairs to foundation walls, walkways or steps, pouring small curbs, steps, or ramps footings for decks, pergolas, walls and more.

In this article you know about how much concrete is in a cubic yard and how to calculate concrete in a cubic yards, and how much is a cubic yd of concrete which will help you making a rough estimate how much concrete you will need. Here, we discussed about how to calculate concrete in cubic yards.
Weight of concrete is defined by weight of its mixture ingredient of cement, sand, gravel and small amount of water. How much is a yard of concrete weigh is depending upon dry concrete, wet concrete, broken concrete, mixing ratio, type of concrete grade, concrete strength, whether it is reinforced or without steel.
How much concrete is in a cubic yard
A cubic yard of concrete measured in cubic feet and bagged concrete. If we figure cubic yards into cubic feet of concrete, there are 27 cubic feet of concrete is in a cubic yard. If you figure cubic yards into bagged concrete, there are either Forty five of 80lb (pounds) or Sixty of 60lb (pounds) bags of concrete is in a cubic yard.
A cubic yard of concrete is unit of measurement of volume, which is visually represented by 3 feet long by 3 feet wide by 3 feet depth, so, 1 cubic yard of concrete is 3’×3’× 3′ = 27 cubic feet, so 1 cubic yard of concrete is equivalent to 27 cubic feet.
To calculate number of bags of concrete is in a yard, divide the one yard of concrete by bags yields in yards. Formula for No. of bags of concrete is in a cubic yard = 1 cubic yard ÷ yields.

To determine yields of premixed concrete bag (80lb, 90lb, 60lb, 50lb, and 40lb) in yards, divide the weight of one bag of concrete in pounds by 3600 (because one yard of concrete weighs about 3600 pounds).
Formula to calculate yields of premixed bag = Weight of one bag of concrete ÷ 3600
● 40 pound bag yields 0.011 cubic yards, yields = 40÷3600 = 0.011 yards
● 50 pound bag yields 0.0138 cubic yards, yields = 50÷3600 = 0.0138 yards
● 60 pound bag yields 0.017 cubic yards, yields = 60÷3600 = 0.017 yards
● 80 pound bag yields 0.022 cubic yards, yields = 80÷3600 = 0.022 yards
● 90 pound bag yields 0.025 cubic yards, yields = 90÷3600 = 0.025 yards.
How much concrete is in a cubic yard?, There are 27 cubic feet (3 feet × 3 feet × 3 feet = 27 cubic feet) of concrete is in a cubic yard. If you figure cubic yards into bagged concrete, there are either Forty five of 80lb (pounds) or Sixty of 60lb (pounds), or Ninety of 40lb, or Seventy two of 50lb, or Forty of 90lb bags of concrete is in a cubic yard.
How to calculate concrete in cubic yards
To calculate concrete in cubic yards, Multiply the length of solid slab by the width to determine square footage. Convert the thickness of solid slab from inches to feet. Multiply the thickness in feet by the square footage to determine cubic feet. Convert cubic feet to cubic yards by multiplying by 0.037.
Steps to calculate concrete in cubic yards are following-
1) Square footage = Length × Width
2) Thickness in feet = Depth in inches/12
3) Cubic feet of concrete = Length (in feet) × Width (in feet) × Thickness (in feet) or Square footage × Thickness (in feet)
4) Cubic yards of concrete = Cubic feet of concrete × 0.037.
For example: To calculate concrete in cubic yards for 12×12 slab at 4″ thick. Ans, maths calculation:- 1) Square footage = 12’×12′ = 144 sq ft, 2) Thickness in feet = 4/12 = 0.33′, 3) Cubic feet of concrete = 144 × 0.33 = 47.52 cubic feet, and 4) Cubic yards of concrete = 47.52 × 0.037 = 1.76 cubic yards. Thus, you will need 1.76 yards of concrete for 12×12 slab.
How much is a cubic yd of concrete
How much is a cubic yd of concrete?, A cubic yd or cubic yard of average strength concrete, which visually is 3 feet long by 3 feet wide by 3 feet tall, is typically weigh around 4050lb (pounds) or 2 tons, and which will cover 81 square feet with a standard depth of 4 inches thick, and will cost between $104 to $144 per cubic yard, with an average of $125 per cubic yard.
To determine the coverage of a cubic yd of concrete in square feet at 3″, or 4″, or 5″, or 6″ thick, Divide 27 cubic feet (because 1 cubic yard is equal to 27 cubic feet) by depth of the concrete slab in feet.
