The 1926 discovery of large limestone deposits at the San Jacinto Estancia inherited from his father led Fortabat to open a cement factory in the nearby pampas hamlet of Loma Negra (south of Olavarría); the choice of location prompted him to christen the company Loma Negra ("Black Mound").

Alfredo Fortabat died in Buenos Aires on January 19, 1976, upon which his widow became the President and nearly sole owner of Loma Negra.
