— Vicat has repeatedly noted its affection for the plant as it was the first cement plant the group purchased outside of France, back in 1974. Indeed, Vicat's group chair and chief executive officer Guy Sidos personally managed the Ragland plant in 2001. However, rather more prosaic reasons may also have been behind the decision to expand Ragland.
