The publisher of Concrete Products and Rock Products has acquired Aggregates Manager, a monthly title geared to crushed stone and sand & gravel producers, from Alabama-based Randall-Reilly. Effective the January 2020 issue, Semco Publishing will merge the magazine into Rock Products. Longtime Aggregates Manager Editor-in-Chief Therese Dunphy will become a monthly contributor and producer of the annual “Aggregates Atlas.”

“The combined resources of Rock Products and Aggregates Manager will give us the largest circulation and broadest audience reach of any publication in the aggregates industry,” says Semco President Peter Johnson. “Rock Products is the aggregates industry's leading publication, and this acquisition, coming as the magazine begins its 125th year of service to the industry, bolsters our commitment to aggregates producers and the advertising base that has supported us for many years."
