The invention relates to a concrete, in particular to a debris concrete belonging to building material field. At present, the concrete with low production cost, high strength, long service life and simple preparation does not exist. The debris concrete comprises cement, water, stone, coal ash, mineral powder, river sand and additives. The debris concrete is characterized in that the debris concrete further comprises debris, the debris is tailing selected by screening during the mechanical processing process of ores, the particle size of the debris is 0.1-5mm, and the particle size of the stone is 5-25mm; wherein, the debris concrete comprises 200-292kg of cement, 185-190kg of water, 1043-1088kg of stones, 56-75kg of coal ash, 44-85kg of mineral powder, 152-257kg of river sand, 5.1-7.7kg of additives and 534-599kg of debris by weight percentage. The debris concrete has low production cost, good concrete compactness and good anti-permeability performance.
