Comparison of several methods of evaluating aggregate gradings
Optimum fineness modulus is used as necessary condition for " optimum gradings"; general mathematical expression is presented for fineness modulus as function of equation of grading curve; then equation is given for optimum fineness moduli of total solid volume which is mixture of cement, sand, and gravel; third equation gives optimum fineness modulus of sand and gravel for various maximum particle sizes, and mix proportions of concrete; by means of these equations, it is shown that gradings defined by generalized Fuller parabola give optimum only within narrow limits of cement and restricted range of maximum particle size.
