Specialty Minerals Building Product Limestones in the Eastern United States—Adams, Massachusetts

Manufacturers of building products in the Eastern U.S. can select from a wide range of ground calcium carbonates (GCCs) produced at the Adams, Massachusetts, plant of Specialty Minerals Inc. (SMI). The large Adams deposit of high-brightness calcite, or crystal calcium carbonate, has been mined since 1848—a long history of service to regional producers of building products.

SMI’s Adams plant produces limestone from 1” landscape chips down to 3 micron industrial grades. Adams manufactures fine-ground GCC for paint, plastics, and other building product applications, sold under the Vicron® GCC and Marblewhite® GCC trademarks. Coarse-ground and screened-stone limestone products, Vical®, ATF™ and Eco-Cal® GCCs, provide excellent value in roofing, masonry, joint compounds, and other building product applications, as well as in agricultural and environmental uses. High-calcium chemical and metallurgical limes are also produced at Adams.

Like all Specialty Minerals-Performance Minerals plants, Adams is certified ISO 9001 and uses rigorous quality monitoring and continuous-improvements processes to provide customers with uniform, high-quality products.
