であつて、フェライト粉末とセメントと水との混練物を
未硬化状態において磁場をかけながら硬化せしめること
を特徴とするものである。Magnetism in this case comes from permanent magnets, magnetic tapes, etc., but these have limitations in shape, size, durability, strength, etc. The present invention eliminates such drawbacks and
This was proposed mainly for the purpose of providing a method for manufacturing a cement concrete body having magnetism that enables control using magnetism in construction work and structures, and is a mixture of ferrite powder, cement, and water. This method is characterized in that it is cured while applying a magnetic field in an uncured state.

Cement and water are measured and mixed according to the specified formulation, adding aggregate and admixtures as necessary, and then poured into the required mold at the factory and molded, or cast at the specified location at the construction site. Then, while it is still in an uncured state, a permanent magnet is placed on the casting surface or an electromagnet is closed, and the thus constructed magnetized cement concrete body can be used to perform the required control. It is something. As described above, the magnetic cement concrete body constructed by the method of the present invention is flexible in shape and size and has excellent durability, so it can be used for magnetic caulking for positioning in underwater and underwater construction. be.
