Florida DOT Concrete Batchman/Operator Practice Exam

What must happen if water comes from a well or is reclaimed?

1. It must not be sampled

2. It must be sampled prior to use

3. It can be used immediately

4. It should be discarded after testing

The correct answer is: It must be sampled prior to use

Water that comes from a well or is reclaimed must be sampled prior to use to ensure its quality meets the necessary standards for concrete production. Sampling is a critical step because it allows for the assessment of the water's chemical properties, contaminants, and overall suitability for mixing with concrete. Testing ensures that the water does not adversely affect the concrete’s strength, durability, or setting characteristics. In the context of concrete production, any variations in the water quality can lead to issues such as setting problems or inadequate bond strength. Therefore, before incorporating this water into the concrete mix, it is essential to conduct thorough testing. This process helps prevent costly problems that could arise from using substandard water and ensures compliance with regulatory standards.
