One cubic yard of concrete weighs around 4,000 pounds. Concrete is measured in cubic yards. Concrete is made out of sand, gravel and cement. Cement is made out of limestone, silica and alumina. Cement is a gray powder that reacts with water to harden the concrete.
The weight also changes as more cement is included in each yard of concrete mix. We learned that some of the heaviest standard concrete is produced in Northeastern Washington. A common recipe for a standard concrete mix design includes 5 bags of Portland cement for each yard of aggregates. The cement is measured in 94 pound increments, or bags. Five bags at 94lbs equals a standard cement weight of 470 pounds per yard of concrete. So here is the rule of thumb that we share with our customers: 1-yard of 5 sack concrete will weigh about 3850 pounds, or 143 pounds per cubic foot.
