concrete walls
Gray structural dividers
Concrete walls are walls made from concrete—a mixture of cement, aggregate, and water that hardens into stone-like material.
The phrase often appears in contexts emphasizing solidity, permanence, or institutional coldness: The concrete walls of the prison blocked all sound.
Figuratively, concrete walls suggest impenetrable barriers: He put up concrete walls around his emotions.
