Valuation of Aggregate Operations for Banking Purposes (Sand
Aggregate is typically divided into two components:! Fine aggregate including sand – material passing a 3/8-inch screen sieve, essentially all passing a # 4 sieve (i.e., a 0.187-inch square opening). ! Coarse aggregate including gravel – generally considered being crushed stone or gravel, almost all of which is retained on a No. 4 sieve.
