What is structure in grinding wheel?

Grinding wheels are generally composed of the 3 elements “abrasive grains (grains)”, “bond” and “pores” as shown in Fig. ... Note that grinding wheels are referred to as conventional wheels* and diamond/CBN wheels* depending on the raw material used, and with diamond/CBN wheels, “structure” is expressed as “concentration”.
