The utility model relates to a building material, and in particular relates to a composite fly ash self-thermal-insulation building block with multiple rows of holes. The technical scheme is that a plurality of rectangular through holes and a plurality of semi-through holes which are vertically staggered are formed in a building block body, wherein every two through holes or every two semi-through holes are isolated through a hole wall; and polystyrene grain injection-molding blocks are arranged in the through holes and the semi-through holes. The composite fly ash self-thermal insulation building block has the beneficial effects that the polystyrene grains are injected and molded into the through holes and the semi-through holes through a hot melting injection-molding technical process, so that radiation and heat exchange in the holes are effectively prevented, thus enhancing the thermal resistance of the hollow building block, improving the thermal insulation performance of the hollow building block and red
