VCAS white pozzolans are derived from a post-industrial stream of by product reinforcement fiberglass made in a glass furnace. It is ground into a white powder finer than 325 mesh. VCAS can replace 15-50% of cement powders used in concrete that adds sustainability to architectural precast products. In earning LEED™ points, VCAS pozzolans can contribute by qualifying as recycled content and sourcing within 500 miles.
