In what sizes of particle the aggregate are deficient or oversupplied?

In fine aggregate, particles smaller than 75 microns can lead to deficiencies in properties like workability and affecting the water requirement, while an oversupply of particles smaller than 75 microns can lead to problems like excessive bleeding and segregation. In coarse aggregate, an oversupply of very fine particles (dust) can affect workability and may lead to a lower strength of the concrete due to reduced paste content.
