Which aggregate type passes through a 4.75 mm sieve with a minimum size of 0.06 mm?

The key idea is classifying aggregate by its largest particle size. If material passes through a 4.75 mm sieve, it is considered fine aggregate, since none of its particles are larger than that opening. The note about a minimum size of 0.06 mm shows there are very small particles present, which is typical for fine aggregate that contains sand-sized grains and finer material. Shape descriptors like rounded, irregular, or angular describe how the grains look and how they pack, but they don’t change the size-based classification. So, with particles from about 0.06 mm up to 4.75 mm, the aggregate fits the fine aggregate category.
