1. Note: % retained and cumulative % retained should be 100% if the experiment was
well conducted, provided the sieves have no tears.
2. %finer should be zero if no particle was let out.
3. To check if the test was properly done, sum the retained weights in the sieve and
subtract from the original weight, then divide by the original weight x 100
4. Retained weight-weight of sample retained in size.
5. % Retained= retained weight/total weight of sample x100.
6. Cumulative retained %= cumulative sum of % retained
7. % finer-100- cumulative retained%
