rubble concrete
Concrete in which large blocks of stone, roughly squared, are placed and arranged roughly in courses, so that they break joint both horizontally and vertically. The stones are placed with not less than 6 in (15 cm) of space between them so that the concrete may be properly rammed. Care is taken that all voids are filled with concrete.
