After washing the aggregate, what is the next step in the process?

• A. Allow it to air dry
• B. Put the sample into an oven at 230 ± 9 F
• C. Weigh it immediately
• D. Mix it with dry aggregate

Answer: (B)

The next step after washing the aggregate is to put the sample into an oven at 230 ± 9°F. This step is crucial as it serves to remove any remaining moisture from the aggregate prior to further testing or usage. The specific temperature range is important, as it ensures that the aggregate dries effectively without being damaged by excessive heat. By drying the aggregate thoroughly in an oven, one can achieve a consistent moisture content, which is essential for accurate measurement and assessment of the aggregate's properties, like weight or density. This step helps to ensure that subsequent calculations, such as those related to mix design or structural integrity, are based on reliable data. Although some may think that allowing the aggregate to air dry might be sufficient, it is typically less controlled and can take significantly longer, resulting in variable moisture levels that could affect the results of any further analysis. Immediate weighing or mixing with dry aggregate prior to drying would not account for moisture content effectively, potentially leading to inaccuracies in subsequent application or testing.
