A gap-graded soil is a soil that has an excess or deficiency of certain particle sizes or a soil that has at least one particle size missing. An example of a gap-graded soil is one in which sand of the No. 10 and No. 40 sizes are missing, and all the other sizes are present.
The grain fineness number (GFN) and particle size distribution of the sand and additives also affect benchlife characteristics of mixed sand. Benchlife: the core quality issue Use of round-grained washed silica sand with a grain fineness number (GFN) of 67 minimized the formation of lustrous carbon wrinkling defects.
