部を生じる結果となる。The application of resin concrete has recently been studied as a new material having thermal and mechanical properties greatly different from those of conventional materials because of the high precision of machine tools. It is a material. The manufacturing process is similar to that of cement concrete as described above, but when the amount of the binder such as epoxy resin or phenol resin is small, unbonded portion is generated in the resin concrete, and the strength is significantly reduced. . On the contrary, when the amount of the binder is large, the temperature-dependent creep becomes large, and it cannot be used as a structural material. Further, even when the optimum amount of the binder is mixed by theoretical calculation, the binder is locally biased, resulting in an unbonded portion.

In the mold 1 fixed on the vibration table 9 and the lid 6 removed, rocks, sand, etc. having an appropriate particle size distribution, Only the aggregate 7 such as alumina, zirconia, silicon carbide or silicon nitride is filled. A binder 8 such as an epoxy resin or a phenol resin is dropped on the aggregate 7. Next, after the mold 1 is covered with the lid 6 and sealed, vacuum is drawn from below the aggregate 7 by using the vacuum pump 4 to remove air existing between the aggregates 7 and the aggregate 7 of the binder 8. Promotes filling between spaces. Then, when the degree of vacuum reaches about 10 to 2 pa, the valve 3 is closed so that the binding material 8 does not enter the vacuum pump 4, and at the same time, pressure is applied from above the dropped binding material 8 using the compressor 5. The pressurization accelerates the filling of the binder 8 between the aggregates 7.

In this method, a gap is instantaneously generated between the aggregates 7 by vibrating, and the binder 8 is filled therein, whereby the binder 8 can be evenly filled. The optimum amount of the binder 8 is uniformly filled between the aggregates 7, and the filling is finished when the liquid level of the binder 8 on the aggregate 7 is not lowered.
