Where can the minimum sample size required for coarse and fine aggregate moisture content testing be found?

The minimum sample size required for coarse and fine aggregate moisture content testing can be found in the Materials Sampling Manual. This manual serves as the authoritative reference for various materials testing processes, including the guidelines for sampling techniques and sample sizes. Knowing the minimum sample size is crucial because it ensures the accuracy and reliability of the moisture content testing, which directly impacts concrete mix design and performance.

The other choices, while they may contain relevant information about aggregates and testing procedures, do not specifically outline the minimum sample size for moisture content testing. The Aggregate Testing Handbook might focus on testing methodologies but not necessarily provide the specific sampling requirements. Field Inspection Guidelines typically relate to the overall inspection processes in the field rather than specific sample size details. The Quality Control Manual may cover broader quality control measures as they pertain to material use, but again, it may not specifically address the required sample sizes for moisture testing.
