What document is used for recording moisture test results?

The appropriate document for recording moisture test results is the PCC plant report. This report serves as a comprehensive record of the quality control measures taken at the plant, including moisture content tests, which are crucial for ensuring proper concrete mixing and performance. Accurate moisture content data is essential because it directly affects the water-cement ratio, impacting the strength and durability of the concrete.

The PCC plant report typically includes specific details about the materials used, test results, and compliance with specified requirements. This ensures that all quality control activities are documented, providing a clear trace of the processes involved in concrete production.

In contrast, other options like the concrete test log, aggregate quality report, and daily inspection report may include relevant data but are not specifically designed for the systematic recording of moisture test results. These documents serve different purposes, such as tracking overall concrete performance or detailing the quality of aggregates, but they do not focus solely on moisture content as part of the concrete batch production oversight.
