Quartz Agglomerate, also known as grindstone, is a composite material made by mixing aggregates such as crushed stone, glass, and quartz with cement binder, then finished with surface grinding and polishing. Quartz Agglomerate made with cement binder is called inorganic grindstone, while that made with epoxy binder is known as epoxy grindstone or organic grindstone. Quartz Agglomerate is further categorized by construction methods into on-site cast grindstone and precast panel grindstone flooring.
