Donate the graduation gown to a local thrift store or vintage clothing store located near a campus, where students shop for gently worn clothing and accessories.
It is the aggregate most of which is retained on 4.75 mm IS sieve and contains only so much finer material as is permitted by specification. According to source, coarse aggregate may be described as: 1  Uncrushed Gravel or Stone â it results from natural disintegration of rock. 2  Crushed Gravel or Stone â it results from crushing of gravel or hard stone. 3  Partially Crushed Gravel or Stone â it is a product of the blending of the above two aggregate.
By this definition the nominal maximum aggregate size for the material example above is also 1/2. However, if there were only 91% passing the 3/8 the nominal maximum aggregate size for that material would be 3/8, not 1/2.y the CT 382 definition, the maximum aggregate size is 3/4 and the nominal maximum aggregate size is 1/2. In the November 2011 version of CT 202, nominal maximum aggregate size is defined as one sieve size larger than the first size to retain more than 10%..
