I'm pushed down another corridor and into a bare concrete room.

The cell was a long concrete room seemingly without furniture.

The report of the big gun echoed through the concrete room.

I was kept in a small, square concrete room which had rat-droppings on the floor.

The gunfire sounded like an explosion in the concrete room.

It sounded like a much larger weapon in the concrete room.

When the stained glass windows shattered, he and the others moved to a small concrete room in the back.

He stepped through the door into a concrete room.

The other's voice sounded hollow from the interior of the concrete room.

The inside of that concrete room was like an oven.
