The weight of concrete per cubic yard, foot and meter

The weight of concrete depends on its composition, but on average, standard concrete weighs about 150 pounds per cubic foot (lb/ft³), which is approximately 2,400 kilograms per cubic meter (kg/m³). This weight includes the concrete's aggregate, cement, and water content.

For smaller quantities, a cubic yard of concrete, which is a common measurement in construction, weighs around 4,050 pounds (lb) or 1,837 kilograms (kg). It's important to note that variations in the mix design, such as the inclusion of lightweight aggregates or the use of different types of cement, can slightly alter the weight of the concrete.

What would be the weight of concrete for a 10m x 10m floor with 100mm depth?

To calculate the weight of a 10x10 meter concrete floor with a 100mm depth, we start by determining the volume of the concrete. The area of the floor is 10 meters by 10 meters, which equals 100 square meters. With the depth of the concrete being 100mm, or 0.1 meters, we multiply the area by the depth to find the volume, resulting in 10 cubic meters.

Given that concrete typically weighs around 2,400 kilograms per cubic meter, we can determine the total weight by multiplying the volume by the weight per cubic meter. The total weight of the 10x10 meter concrete floor, with a 100mm depth, would be approximately 24,000 kilograms, or 24 metric tons.

Can the concrete mix affect the weight?

Yes, the type of concrete mix can significantly affect its weight. The weight of concrete is primarily determined by the materials used in the mix, including the type of aggregate, the water-cement ratio, and any additional admixtures.

For example, standard concrete uses aggregates like gravel or crushed stone, which contribute to its typical weight of about 2,400 kilograms per cubic meter (150 pounds per cubic foot). However, if the mix uses lightweight aggregates such as expanded clay, shale, or pumice, the weight of the concrete can be reduced to as low as 1,800 kilograms per cubic meter (112 pounds per cubic foot). This type of lightweight concrete is often used in situations where reducing the overall weight of a structure is important.

Conversely, high-density concrete uses heavier aggregates like barite, magnetite, or iron, which can increase the weight of the mix to around 3,800 kilograms per cubic meter (237 pounds per cubic foot). This type of concrete is typically used in specialized applications, such as radiation shielding in medical or nuclear facilities.

The water-cement ratio also plays a role. A higher water content can increase the concrete's density and thus its weight, while lower water content might result in a lighter mix, though this also affects the concrete's strength and workability.
