Florida DOT Concrete Batchman/Operator Practice Exam

Approximately how much volume does one bag of cement equal?

1. 0.5 cubic feet

2. 1 cubic foot

3. 1.5 cubic feet

4. 2 cubic feet

The correct answer is: 1 cubic foot

One bag of cement typically equals 1 cubic foot in volume. This measurement is an industry standard for a standard 94-pound bag of Portland cement, which is one of the most commonly used types in construction and concrete batching. Understanding this volume is essential for batch calculations, as it helps in determining the proportions of the different materials needed in a concrete mix design. Accurately knowing the volume of a bag of cement allows operators to efficiently mix concrete by complying with specified ratios of cement, aggregates, and water. This is crucial for achieving the desired strength and durability of the concrete. The other options suggest different volumes, which would not align with the standard practices in the field, causing confusion in mix design and potentially leading to mix errors if used incorrectly.
