Florida DOT Concrete Batchman/Operator Practice Exam

According to the Standard Specifications, concrete batch water must meet the requirements outlined in which section?

1. Section 912

2. Section 923

3. Section 934

4. Section 943

The correct answer is: Section 923

The correct choice is based on the specific requirements set forth for concrete materials in the Standard Specifications. Section 923 typically addresses the requirements for various concrete materials, which includes aggregates, cement, and other components crucial to concrete production. In the context of water used in batching concrete, it is vital that the water meet certain quality standards to ensure the durability and strength of the final product. Section 923 outlines the guidelines for acceptable water characteristics, including limits on impurities that could negatively influence the hydration process of the cement or impair the concrete's characteristics. This is critical to achieve the desired properties of the concrete, such as strength and workability, as well as to prevent issues like efflorescence or corrosion caused by harmful substances present in the water. The other sections mentioned focus on different aspects of materials and construction practices. While they are also relevant to concrete production, they do not specifically address the requirements for batch water with the same detail or emphasis as Section 923, which is why this section is the correct reference for concrete batch water standards.
