# Weight of concrete per cubic foot?

## Weight of concrete per cubic foot?

weight of concrete per cubic foot vary in different concrete mix design, It is an important factor to know the weight of any section of concrete that is being cut and the weight of the concrete is approximately 150 pounds per cubic foot. The formula for calculating the weight of concrete is The piece should not be more than 1000 pounds each if removing the piece with a skid steer and it is important to remember that the more it will weigh when the reach of skid steer is exceeded. Be sure not to exceed the maximum lifting required by the particular forklift if a forklift is being used.

Use a forklift for the smaller pieces to avoid injuries and the piece should be about 75 to 125 pounds if you need to remove concrete by hand. It is important to remember to transfer much of the weight to the legs while doing any lifting.

### Slabs:

The table is based on the cubic foot of cured concrete with an average weight of 150 lbs;

 SIZE THICKNESS WEIGHT 3 x 7 ft 6 in 1,575 lbs 4 x 8 ft 6 in 2,400 lbs 5 x 10 ft 6 in 3,750 lbs 8 x 10 ft 6 in 6, 000 lbs ### Determine The Density Of Concrete:

Density (p) = mass (m) ÷ Volume (v)

The density of the aggregates depends on the type of stone which is used and the density of the concrete is 3.15 g/cm3. Gravel has a much higher density than the vermiculite and the density of typical concrete mix is 2.4 g/cm3.

The density of concrete in different units of measure is

 Volume Weight 1 in3 1.39 oz 1 ft3 150  lb 1 yd3 4050 lb 1 m3 2400 kg

### How Much Does Concrete Weight: Density is a simple mass to volume ratio and the most accurate way to calculate the density of concrete is to measure known volume and weighing it. The density of concrete is checking the strength by using test cylinders and a reduced density of normal concrete always means that there is a higher content of water which lowers the strength of concrete.

To predict possible strength these strength tests are done at 24 hrs, 7 days and 28 days in the lab. Normal weight concrete weighs about 18 lbs per square foot with a standard thickness of 1.5 inches and lightweight concrete weighs 14.5 lbs per square foot with a standard thickness of 1.5 inches.

### To Calculate How Much Square Foot Of Concrete Weighs:

To figure the weight of square foot of concrete is based on how thick concrete is and there is a simple calculation for it given below;

Cubic foot concrete weighs 145 pounds

For the depth in feet divide the thickness of your concrete with 12.

E.g. 6 inches slab of concrete

6/12 = 5

Then multiply the 5 feet thickness with 145 ponds & you get 72.5 pounds.

So this is calculated that a 6-inch thick slab weighs 72.5 pounds per square foot.
