Crystalline silica (quartz) is the form of silica that OSHA is writing the new regulations to cover, it is a health hazard. It is not reactive with Portland cement meaning it does not cause ASR (Alkali Silica Reactivity) regardless of particle size. Lots of countertop makers use 30 to 40 mesh crystalline silica sand in their GFRC mixes.
