| The pozzolan increases the strength of the concrete and reduces the corrosion of the rebar in the concrete. New potential markets include shrimp farms in Asia, ceramic bricks, pozzolan for concrete, land-fill odor control, nuclear remediation, agricultural air filtration, cardboard additives, a road and sidewalk non-slip product, synthetic-turf filler, pet-food additive, ammonia-removal for commercial aquaculture, explosives and a variety of specialty applications. United States Antimony Corporation (OTCBB:UAMY) announced that its Bear River Zeolite Subsidiary is vigorously pursuing research on the application of its zeolite ("BRZ") as a natural pozzolan (cementiceous product) for various large markets in the cement/concrete industry. |
