Florida DOT Concrete Batchman/Operator Practice Exam

Aggregates must be measured within what percentage accuracy of the required amount?

1. 0.5 percent

2. 1 percent

3. 2 percent

4. 5 percent

The correct answer is: 1 percent

When measuring aggregates for concrete production, achieving precision is essential to ensure the quality and durability of the final product. The standard requirement is that aggregates must be measured with an accuracy of 1 percent of the required amount. This level of precision helps maintain consistent mix designs, leading to predictable performance in the concrete's properties, such as strength and workability. Measuring within this tight margin of 1 percent ensures that any variations in the materials used do not compromise the overall quality of the concrete, which could lead to issues down the line such as increased permeability, reduced longevity, or even structural failures. Adhering to this standard reflects both industry best practices and regulatory compliance, particularly in contexts like Florida DOT projects, where the reliability of the materials is critical to the safety and performance of infrastructure.
