繊維には木材から得られたものは除外される。Hereinafter, the present invention will be described in detail. Examples of the plant fiber used in the present invention include one or more kinds of various straws such as bamboo, rice, wheat, and haze, rice husk, wheat grass and the like. Bamboo is used by cutting dried ones to a length of about 5 to 10 cm, crushing and opening the fibers. As the straw, a dried straw cut into a length of about 5 to 15 cm is used. As for the rice husk and the wheat husk, the dried one can be used as is. The plant fibers used in the present invention exclude those obtained from wood.

The compounding ratio of the plant fiber and the cement is preferably 5 to 10 with respect to 1 part by weight of cement, but the plant fiber may be further increased. Further, the water-cement ratio is in the range of 50 to 65% by weight as in the case of ordinary mortar.

However, since the content of these aggregates increases the specific gravity of the concrete product, it is necessary to keep the content of the aggregate small. It is also possible to mix lightweight aggregates and chemical fibers such as polyester filaments, nylon filaments, and vinylon fibers. Further, in the present invention, various cement admixtures such as an AE agent can be added.

By pouring this kneaded product into various curing molds and curing, a target concrete product can be obtained. At the time of pouring into the forming die, it is also possible to previously put a wire net, a welding net of small diameter reinforcing bars, etc. in the forming die and pour it to obtain a concrete product reinforced by these wire nets and reinforcing bars. Further, upon curing, a method of curing and curing in steam is also possible.
