Salt River Materials Group

What Salt River Materials Group does

Salt River Materials Group (SRMG) is a privately-held, tribally-owned construction materials supplier headquartered in Scottsdale, Arizona, and wholly owned by the Salt River Pima-Maricopa Indian Community (SRPMIC). Founded in 1959 with the original Clarkdale cement plant, SRMG operates through two core subsidiaries—Phoenix Cement Company (acquired 1987) and Salt River Sand & Rock Company (established 1981)—serving as the commercial marketing arm for both. The company manufactures and distributes portland, masonry, and blended cements (Phoenix Cement®, Dynamortar®, Supermortar® brands), fly ash and pozzolans (Phoenix Class F Fly Ash, Harvested Fly Ash, Blended Fly Ash, Tucson Pozzolan, bottom ash, cenospheres), and both normal and lightweight aggregates, with products meeting ASTM C150, C595, C618, C91, C33, and C330 specifications.

SRMG's production technology includes energy-efficient cement manufacturing with the first U.S.-installed vertical roller mill for finish grinding at the Clarkdale Plant, alongside proprietary fly ash harvesting and beneficiation equipment that reclaims previously landfilled coal combustion products. The 2020 Coronado Harvesting Project added 300,000 tons per year of reclaimed Class F fly ash to the supply network, addressing industry-wide shortages driven by coal plant retirements. The company generates revenue through one-time product sales via direct bulk distribution, retail pickup, a network of ~24 terminals and plants across Arizona, California, Nevada, New Mexico, and Utah, and on-site ready-mix partner batching arrangements. Customers include state and federal transportation departments (pre-approval from 9 agencies including ADOT, TxDOT, Caltrans), ready-mix concrete producers, and commercial/residential construction projects, with notable installations at Spaceport America, Phoenix Children's Hospital, and Salt River Fields. SRMG holds 16 consecutive years of ENERGY STAR certification and is the only Native-American owned cement manufacturer in the United States.
