Jul 23, 2020 If the actual grading curve lies above the specified grading then the aggregate is considered to be coarser. Such type of aggregate in a concrete mix is at a high risk of segregation. When the actual grading curve is flatter than the specified grading curve, then the aggregate may be deficient in the middle size particles.
