After cooling to room temperature, how are coarse aggregates weighed?

Coarse aggregates are typically weighed to the nearest whole gram after cooling to room temperature due to the practical considerations in construction and materials testing. This level of precision is sufficient for most engineering applications, where small variances in weight can significantly impact calculations and mix designs. Weighing to the nearest whole gram reduces the potential for errors while still maintaining a level of accuracy that meets industry standards.

Choosing to weigh to finer increments like tenths of a gram, while theoretically more precise, is often unnecessary for coarse aggregates due to the variability in particle size and density of the aggregates themselves. Weighing them to the nearest ounce or kilogram may introduce unwanted rounding errors or be too coarse for precise mixture calculations when working with aggregate in construction applications. Thus, weighing to the nearest whole gram balances accuracy with practicality in the context of aggregate measurement.
