In the automated brick manufacturing process, clay was extruded and cut into uncured (green) bricks, which were coated with a parting agent, commonly containing crystalline silica. In the manual process, clay was hand thrown into wooden moulds to form green bricks. These moulds and bricks were coated with the parting agent by hand. Green bricks were dried to remove excess moisture before being
PC is a bit different than just plain sand. Heres why: The components of polymeric sand vary from manufacturer to manufacturer, but in general, the main ingredients are quartz and crystalline silica (sand) and a manmade polymer binder (a sort of proprietary glue).

When laying pavers, polymeric sand is commonly used to fill the gaps between each stone and to keep them in, polymeric sand contains 85 90% quartz and crystalline silica, which is what gives the sand its extreme binding power. When you wet this sand, it activates the polymers, which hardens the various components, effectively locking the pavers in place.

Remove polymeric sand from pavers with a leaf blower. Polyermic sand normally contains 8590 percent quartz and crystalline silica, which gives the sand its binding power. The sand fills the joints between pavers, keeping them locked in place and offering a stable and firm foundation. Wetting the sand activates the polymers, hardening the components to lock the pavers in place.
Switch to a wire brush and scrub the surface of the paver to remove any remaining concrete particles.
