What is the weight of a cubic yard of concrete?

The most widely accepted weight of a cubic yard of concrete is around 4000 to 4200 pounds, depending on the mix design and the presence of aggregates. The figure of 4040 pounds falls within this acceptable range, making it a reasonable estimate for concrete weight. The weight can vary slightly based on the specific materials used and their densities, but generally, a value near 4000 pounds is commonly used for calculations in construction and material estimates.

When determining the specific weight for a project, it's important to account for potential variations due to moisture content, additives, or different types of aggregates, but in a general sense, 4040 pounds provides a standard reference for the weight of a cubic yard of concrete.
