Abstract
An experimental investigation has been made into the effects of a number of factors on the results of stove analysis of natural sands. The factors studied included samples size, particle size distribution in the sample and the duration of sieving. Microscopic examination showed that the particle shape was similar in all the materials tested regardless of size. The work showed that overloading of the sieves leads to inaccurate results, and that reduction of sample size is a more effective remedy for overloading than prolongation of sieving time. Values are given for the maximum desirable loading for a number of sieves, and recommendations are made for the adoption of a standard weight of sample for sieve analysis of natural sands. The most recent British Standard method for Sieve Analysis (B.S. 882:1944, Appendix B) has been based on this work.
