Discussion: > for fine aggregate (sand): 1. Draw a relationship between sieve size (mm) (x-axis) and % passing (sand) (y-axis). 2. Draw the limits of the standard with curve (1). 3. Is the grading of the sample within the limits? Discuss the curve. 4. Calculate the fineness modulus of sand? 5. What is the average particle size of the sample? For coarse aggregate (gravel): 1. Draw a relationship between sieve size (mm) (x-axis) and % passing (gravel) (y-axis). 2. Draw the limits of the standard with curve (1). 3. Is the grading of the sample within the limits? Discuss the curve.
