The four graphs are titled Planar Void Ratio Radius Expansion for six-millimetre Diameter, zero point nine one five-metre Drop Height, with zero Sieve, one Sieve, two Sieves, and three Sieves. The horizontal axis is Planar Void Ratio from zero point two to one point eight. The vertical axis is Cumulative Density from zero to one point zero. Each graph includes an empirical cumulative distribution function curve, a Normal Distribution Fit curve, and a Lognormal Distribution Fit curve. For zero Sieve, the legend lists mean zero point seven eight one, standard deviation zero point two zero five, and maximum gradient nineteen point four six. For one Sieve, mean zero point seven eight four, standard deviation zero point one eight three, and maximum gradient nineteen point three one. For two Sieves, mean zero point seven eight eight, standard deviation zero point one eight six, and maximum gradient twenty-six point six eight. For three Sieves, mean zero point seven nine two, standard deviation zero point one nine seven, and maximum gradient seventeen point eight two.Empirical cumulative density function of planar void ratio of 6 mm spherical particles specimen prepared by radius expansion from 0.915 m drop height with various numbers of sieves
