Fineness Modulus
The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6. And if Mx is within 3.7 ~ 3.1, it is coarse sand; if Mx is within 3.0 ~ 2.3, it is medium sand; if Mx is within 2.2 ~ 1.6, it is fine sand; and if Mx is within 1.5-0.7, it is superfine sand which should be considered specifically when concrete is prepared.
