What is the normal weight of concrete in pounds per cubic foot?

• A. 120 lb/ft^3
• B. 150 lb/ft^3
• C. 180 lb/ft^3
• D. 200 lb/ft^3

Answer: (B)

The normal weight of concrete is commonly accepted to be around 150 pounds per cubic foot. This value is a standard reference used in engineering and construction calculations and is derived from the average density of concrete materials, typically consisting of aggregates, water, and cement. Concrete density can vary based on the type of aggregate used, moisture content, and the specific mix design, but for most conventional concrete, the weight is around 150 lb/ft^3. This standard allows engineers and construction professionals to estimate loads and perform structural calculations accurately. While lighter or heavier concrete mixes exist, they are usually specialized formulations for specific applications, such as lightweight concrete for thermal insulation or heavyweight concrete for radiation shielding. However, for general construction and design purposes, the 150 lb/ft^3 figure remains the benchmark.
