How Much Does Concrete Weigh?
One cubic meter of standard concrete weighs approximately 2,400 kilograms (2.4 tonnes) or 5,291 pounds. Because concrete is a composite material made of cement, water, and various aggregates, its exact weight depends heavily on the specific mix design used.
Density varies significantly by mix type. Lightweight mixes use expanded shale or clay aggregates and typically weigh between 1,600 and 1,900 kg/m³. Standard normal-weight concrete, used in most residential and commercial projects, has a density of 2,300 to 2,500 kg/m³. Heavyweight concrete, typically used for radiation shielding in medical facilities or nuclear plants, uses dense aggregates like barite or hematite and can reach extreme densities of 3,200 to 4,000 kg/m³.
Concrete Density Reference Table
| Type | Density | Weight per m³ | Weight per ft³ |
|---|---|---|---|
| Lightweight | 1,760 kg/m³ | 1,760 kg | 110 lb |
| Standard | 2,400 kg/m³ | 2,400 kg | 150 lb |
| Reinforced | 2,500 kg/m³ | 2,500 kg | 156 lb |
| Heavyweight | 3,200 kg/m³ | 3,200 kg | 200 lb |
Frequently Asked Questions
How much does 1 cubic meter of concrete weigh?
Standard concrete weighs approximately 2,400 kg (2.4 metric tonnes) per cubic meter. This equals about 5,291 pounds per cubic yard.
What is the weight of 1m³ of concrete in kg?
1 cubic metre of standard concrete weighs approximately 2,400 kg. For M20 grade with 20mm aggregate, the density is typically 2,395–2,420 kg/m³.
How much does a concrete slab weigh per square foot?
A standard 4-inch concrete slab weighs approximately 50 pounds per square foot (based on 150 lb/ft³ density × 0.333 ft thickness).
