To provide a concrete structure represented by a concrete block, which is mixed with, for example, broken pieces of concrete or crushed pieces of a stone material set to a standardized size in a uniformly arranged state, or the like, and a method for manufacturing the concrete structure excellent in workability.
Each of concrete structures 5 and 5' is mixed with a large number of broken pieces 3 of the concrete or stone material adjusted to a desired predetermined size or below in an almost uniformly arranged state and manufactured using a process (a) for casting ready-mixed concrete 2 in the form of the concrete structure, a process (b) for arranging a measure frame body, which is equipped with a measure for sieving the broken pieces 3 of the concrete or stone material so as to have the desired predetermined size, on the upper surface of the ready-mixed concrete 2, a process (c) for uniformly distributing the broken pieces 3 of the concrete or stone material to the measure frame body and a process (d) for detaching the measure frame body from the form and leaving the broken pieces 3 of the concrete or stone material passed through the measure frame body in the form.
