Description of the Related Art Cement press moldings used for flooring materials, wall materials, etc. are obtained by adding aggregates such as silica sand to cement and press molding. As a conventional cement press product, artificial aggregate (for example, shirasu balloon) is added instead of silica sand to reduce the weight.
Further, it is known that reinforcing fibers such as glass fibers are added to increase the strength (for example, JP-A-62-108782).

0-40% by weight, preferably 10-30% by weight, more preferably 15-20% by weight of shirasu balloon is added. In the present invention, the shirasu balloon is preferably spherical. This is because if the shirasu balloon is spherical, the fluidity of the shirasu balloon at the time of kneading and molding is increased, and the above-mentioned reinforcing fibers can be dispersed better. As a result of the better dispersion of the reinforcing fibers, it is possible to further increase the amount of the fibers added, which is preferable because it increases the strength of the molded product as the final product. The particle size of the shirasu balloon is 30-100 μm in average particle size.
It can be said that the degree, preferably about 40 to 50 μm, is more preferable from the viewpoint of improving the fluidity. If the addition amount of shirasu balloon is less than 10 parts by weight, the effect of weight reduction is not sufficient, and if it exceeds 40 parts by weight, the strength of the molded product is remarkably lowered, which is not preferable. Further, it is preferable that the shirasu balloon has a spherical shape because its pressure resistance is improved and damage during kneading molding can be prevented. The shirasu balloon is a hollow body made of glass, for example,
What is obtained by heat-treating the volcanic glass fine particles contained in Shirasu at around 1000 ° C.
