Polished Stone Value

Polished paver value determination The polished paver value determination makes use of the BS812 aggregate abrasion method to polish the samples of pavers the abrasion lap is modified by attaching a standard rubber disk and emery and emery abrasives are fed to the samples under test in the same way as in the BS812 determination.
