Introduction

The follo*ing is a la" reort "ased on determining the various sizes of articles in

a samle of aggregates This rocess *as done for course and fine aggregates

involving e+ual distri"ution through rifle "o, method and assing the aggregates

through t*o different sets of sieves *ith various sieve sizes corresonding to the

tye of aggregates used and o"taining the values for the aggregate masses that had

"een retained *ithin each sieve

- grading curve can then "e o"tained "y finding the ercent assing and lotting

them on the semi log curve# sho*ing the distri"ution of the ercentage of

aggregates assing against the sieve num"er *as lotted

.rain size is needed for the classification of soils The data o"tained from lotting

curves can "e used to design filters for earth dams and to determine suita"le soils

for road construction and other "uilding ro/ects and also the grain size can

determine the *ater flo* through various soil tyes and allo*ing roer allocation

of "uilding sites
