What is the weight of a cubic foot of concrete?

1. 100 pounds

2. 150 pounds

3. 200 pounds

4. 250 pounds

The correct answer is: 150 pounds

A cubic foot of concrete typically weighs around 150 pounds. This value is widely accepted in construction and engineering, as it reflects the density of standard concrete mix, which consists mainly of cement, water, and aggregates. Understanding the weight of concrete is crucial for hoisting and rigging operations, as it directly impacts the load calculations and safety considerations when moving or supporting heavy materials. Knowing this weight helps operators select appropriate equipment, such as cranes or hoists, that can safely handle the expected loads. This knowledge also aids in the estimation of how many bags of concrete will be needed for a specific volume, which is essential for project planning and material management.
