Description of the Related Art Conventionally, cast-in-place concrete is solidified in a static state, but in the case of a centrifugal tube method, a method of rotational molding at high speed is adopted. However, in the centrifugal tube method, since the rotational molding is performed at a high speed as described above, a large amount of fine particles in the cement are discharged and a slurry called so-called latance is generated. The generation rate of this slurry was 5 to 20% of the amount of cement used, and the sludge treatment required enormous cost for post-treatment as waste. Moreover, latance is currently a large amount of waste because it cannot obtain its own cement strength.

The amount of industrial waste generated in the limited land area is currently reaching the limit when it is treated and discarded. The latance generated from the secondary cement product has a large amount and a high pH, contains a small amount of heavy metals, and does not solidify and strengthen.

Natural scenery is something that can not be colored, it was seen in the red walls and pyramids of the Chinese palace in the old days, and if it was the original gray color of conventional cement, it seems that today's cultural and artistic significance was low.
