What type of scale is used to measure fine aggregate?

The correct answer is that a gram scale is specifically designed for measuring smaller quantities of fine aggregate with a high degree of accuracy. Fine aggregate, which includes materials like sand, is usually present in relatively small amounts in concrete and other construction materials.

A gram scale provides precision at a finer resolution than other types of scales, enabling accurate measurement of the often minimal weight of fine aggregates. This is crucial in quality control during construction and material testing, as even small deviations can impact the overall quality and performance of concrete mixes.

Using a gram scale minimizes the likelihood of over- or under-measuring fine aggregates, which can affect the balance and properties of the concrete mix. Because of this precision, it is a preferred choice in laboratory settings where the exact proportions of materials are essential for achieving desired strength and durability in concrete applications.
