Ready mix concrete is mixture of Portland cement, sand and aggregate with some admixture like accelerator, reducer, plastisizer. Each ingredients of concrete required in adequate quantities according to achieve targeted compressive strength or design of a concrete structure.

Ready mix concrete can be used for building or repairing foundation walls, fence post, sidewalks, curbs, steps and ramps and for setting posts and others concrete structure like, footing, slab, beam and columns.

Weight of a bag of concrete can varies in different country. In United State a bag of concrete available in different weight such as 90lb, 80lb, 60lb, 50lb & 40lb. In United Kingdom it is measured in Imperial and metric system in other countries. Others concrete bag size is 40kg, 30kg, 25kg & 20kg.

Weight of Ready mix concrete in dry condition is about 133 lbs per cubic foot, 3600 lbs per cubic yard, 17.826lb/gallon, 21.36kN/m3, 2.136kg/litre, 1.234 oz/ inch^3, 60kg/CF, or which is approximately equal as 2136 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.

In this articles you know about, how many cubic feet are in a bag of concrete. This will help to viewers in better understanding and it is easy to choose the most suitable bag size of concrete you wanted according to requirement.

## How many cubic feet are there in a bag of concrete

Quikrete’s Concrete Mix yield’s about 0.15 cubic feet for every 20 pounds of mix, so a 40-pound bag yields 0.30 cubic feet, 60 pounds of concrete mix yields 0.45 cubic feet, an 80-pound bag yields 0.60 cubic feet and 90lb bag yields 0.68 cubic feet.

Volume of a concrete bag measured by their yields, their yield in cubic feet is calculated by dividing weight of one bag of concrete mix by weight of one cubic foot of concrete. Generally weight of ready mix concrete in dry condition is about 133 lbs or 60kg per cubic foot.

Calculation of yields of a concrete bag in cubic feet:-

● yields of 90lb = 90/ 133 = 0.676 cu ft

● yields of 80lb = 80/ 133 = 0.60 cu ft

● yields of 60lb = 60/ 133 = 0.45 cu ft

● yields of 50lb = 50/ 133 = 0.375 cu ft

● yields of 40lb = 40/ 133 = 0.30 cu ft

● yields of 40kg = 40/ 60 = 0.66 cu ft

● yields of 30kg = 30/ 60 = 0.5 cu ft

● yields of 25kg = 25/ 60 = 0.416 cu ft

● yields of 20kg = 20/60 = 0.33 cu ft
