Type the % passing of the 20 mm and 10 mm fractions at each sieve, and their proportions in the boxes under “% of Different Fractions”, or leave the sheet empty to print a blank format. Each fraction's share (% passing × proportion / 100) and the combined gradation are worked out as you type; on screen, a combined value outside the IS 383 limit is highlighted. Typed values are saved for this project.
