As one of leaders of aggregate grading curves for concrete industry, SBM always seeks innovation & excellence.
Grading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained

The same fineness modulus can represent a number of different size distributions and grading curves. Therefore, fineness modulus cannot be used as a description of the grading of aggregate. When the use of the fineness modulus in the assessment of variations from the same source or parabolic behavior of a concrete mix is of great help.

Grading on a curve is a term that describes a variety of different methods that a teacher uses to adjust the scores her students received on a test in some way. Most of the time, grading on a curve boosts the students' grades by moving their actual scores up a few notches, perhaps increasing the letter grade.Some teachers use curves to adjust the scores received in exams, whereas other
