Case Overview

This antitrust class action alleges that Defendants—the major manufacturers of Cement Chemical Additives (CCAs)—entered into an unlawful agreement to fix the prices of concrete admixtures, cement additives, admixtures for mortar, and related bundled products. CCAs are added to concrete, cement, and mortar to improve performance characteristics such as water reduction, set time, shrinkage control, stabilization, crack prevention, and corrosion inhibition. The global market for CCAs exceeded $18 billion in 2020 and $27 billion in 2022. Plaintiffs allege that Defendants’ price‑fixing scheme caused direct purchasers in the U.S. and its territories to pay supra‑competitive prices from at least May 11, 2018 through the date of class certification, in violation of Sections 1 and 3 of the Sherman Act.
