PROBLEM TO BE SOLVED: To provide a method of producing a concrete block suitable to be manufactured in a large quantity. ;SOLUTION: A frame structure 1 including detachable side frame members and a detachable bottom frame member 1B and including a concrete inlet hole formed on an upper portion thereof, is arranged in a manner such that the concrete inlet hole is located at an upper position. Then, an amount of concrete is poured into the frame structure 1 through the concrete inlet hole. Upon hardening of the concrete to some extent, the frame structure 1 is raised upwardly and turned so that the concrete inlet hole is located at a lower position. After the frame structure 1 filled with the concrete has been moved to a predetermined place, the concrete which is partially solidified is detached from the frame structure 1 and is caused to solidify still further, thereby obtaining the desired concrete block.;COPYRIGHT: (C)1998,JPO
