How much does a 12×12 concrete slab weigh | how much concrete do i need to make a 12×12 slab.

Concrete is the mixture of Portland cement, sand (fine aggregates), gravel (coarse aggregate), water and different types of approved admixture or ingredients.

Concrete is used 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.

Question is how much does a 12×12 concrete slab weigh? Weight of concrete slab is measured by mass in kg, pound or tons which is equal as Volume times density in similar units. Thus, weight of concrete slab = Volume of slab × density.

Volume of concrete slab is length times width times by thickness, that is Volume = Length × width × thickness. Volume is expressed in different units such as cubic yards, cubic feet, or cubic meters. Density of concrete slab or unit mass of concrete is 4,050 pound per yard, or 2400kg/m3, or 150 pound per cubic foot, or 68kg per cubic foot.

A cubic yard of solid slab of concrete, which visually is 3 feet long by 3 feet wide by 3 feet tall, is typically weigh about 4,050lb (pound) which is approximately equal as 150 pound per cubic foot. A Broken concrete weighs about 2,025lb (pound) per yard which is approximately equal as 75 pound per cubic foot.

A cubic meter of solid slab of concrete, which visually is 1 meter long by 1 meter wide by 1 meter tall, is typically weigh about 2400kg (kilograms). A cubic feet of solid slab of concrete, which visually is 1 feet long by 1 feet wide by 1 feet tall, is typically weigh about 150lb (pound) or 68kg (kilogram).

In this article we know about “how much does a 12×12 concrete slab weigh at 4 inches thick” and how much concrete do i need to make a 12×12 slab.

A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 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.

**How much does a 12×12 concrete slab weigh**

To calculate the weight of 12×12 concrete slab at 4 inches thick, you multiply the volume of concrete slab by density in similar units. To calculate volume of concrete slab, you use the formula: Volume = L x W x H. Density of concrete is 150 lbs per cubic foot, or 4,050 lbs per cubic yard.

**● How do you measure for concrete**

**● How to figure out concrete yardage**

Calculating the volume for concrete slab requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

**Steps to calculate weight of a 12×12 concrete slab in pound or in US Tons, proceeded as follows:-**

1) 4 inches in feet = 4÷12 = 0.33′

2) Square footage of 12’×12′ slab = 12×12 = 144 sq ft

3) Volume of concrete slab in cubic feet = 144 × 0.33 = 47.52 cubic feet

4) Volume of concrete slab in cubic yards = 47.52 ÷ 27 = 1.76 yards

5) Weight of 12 by 12 slab in pound = 47.52 × 150 = 7,128 pound

6) Weight of 12 by 12 slab in US Tons = 7,128 ÷ 2,000 = 3.6 tons approximately.

A 12×12 concrete slab at 4 inches thick is about 1.76 cubic yards or 47.52 cubic feet, which weigh approximately 7,128 pounds or 3.6 US tons. If you want to calculate the weight of concrete by cubic foot, just divide the cubic yard weight by 27. Coincidentally, the weight of one cubic foot of concrete weighs about 150 pounds.

A 12×12 concrete slab at 4 inches thick weighs approximately 7,128lb (pound), which is approximately equal as 3.6 US tons. To make a 12 by 12 concrete slab at 4 inches thick, you will need approximately 1.76 cubic yards or 47.52 cubic feet of concrete. One cubic yard of concrete slab weighs about 4,050 pounds.

To make a 12×12 concrete slab at 4 inches thick, you will need approximately 1.76 cubic yards or 47.52 cubic feet of concrete, which weigh about 7,128lb (pound), or 3.6 US tons.
