料費等である。 Today, the most common molding material used as an inorganic excipient is clay. Clay molded bodies sintered in a kiln have a unique texture as ceramics, and hold a firm position in industry as works of art and items for daily use. In the field of education, it is also used as an ideal teaching material for developing and nurturing children's creativity and artistry. However, there are currently few opportunities to employ this excellent molding material due to the various problems listed below. The problems mainly stem from the fact that sintering is a difficult operation that is essential; first, there is a lack of skilled workers for the above operations, second, the installation of expensive kilns, and third, high fuel costs, etc. It is.

である。 The present invention has been made in view of the above circumstances, and the molding material of the present invention does not require a sintering operation, is self-hardening, and has excellent moldability and shapeability. Furthermore, the strength of a molded product that has been sufficiently cured after molding far exceeds that of ceramics, and is an excellent molding material in that respect as well. However, when used industrially to manufacture secondary cement products, it is generally necessary to adopt a specific kneading procedure and to mix in reinforcing materials because the strength is insufficient.

Polymers, polyvinyl alcohol, etc. can be used. It is desirable to mix 1 to 5 parts by weight of this organic binder per 100 parts by weight of Portland cement. If the amount of the binder mixed is less than 1 part by weight or more than 5 parts by weight, properties such as moldability and plasticity that meet the objectives of the present invention cannot be imparted.

の目的に適う組成物は得られない。 The inorganic plasticizer in the present invention is an inorganic powder consisting of fine particles and is a substance that imparts plasticity to a kneaded material. In view of ease of availability and moldability of the resulting molding material, it is desirable to use clay minerals. As the clay mineral, any one of kaolin, bentonite, Kibushi clay, Frogme clay, and Shiba clay may be selected. The amount of inorganic plasticizer to be used is particularly preferably 5 to 20 parts by weight per 100 parts by weight of Portland cement in view of the balance of physical properties of the composition such as plasticity and formability. If the amount of the plasticizer incorporated is less than 5 parts by weight or more than 20 parts by weight, a composition suitable for the purpose of the present invention cannot generally be obtained.

賦形性を附与し得ない。 In the first step, Portland cement and an organic binder are mixed in a sufficiently dry state. In the second step, water in which a cement water reducing agent is dissolved is added to the mixture obtained in the first step and kneaded. The kneading time at this stage is 5 to 15 minutes, preferably 7 to 10 minutes. If the kneading time is less than 5 minutes, the kneaded product will lack plasticity. On the contrary, if the time is longer than 15 minutes, the plasticity gradually decreases, which is not preferable. In the third stage of mixing, a powdered inorganic plasticizer is added to the kneaded material obtained in the second stage and the mixture is kneaded. It is preferable that this kneading time is 5 minutes or more. If the dispersion of the plasticizer is insufficient within 5 minutes, one of the objects of the present invention, high moldability, is achieved.
It is not possible to impart excipient properties.
