PROBLEM TO BE SOLVED: To accurately find the volume of a test piece by making a form high in molding precision and large in strength, making the cylindrical test piece to be formed high in density, and eliminating variance in diameter.SOLUTION: An outer frame cylinder 2 is formed by pairing two semicylindrical bodies 3, and combining both the semicylindrical bodies 3 while making corresponding surfaces of axial edge surfaces 4 be opposed to each other. Both semicylindrical body combining/separating means 5 etc., is provided which can separate the external frame cylindrical body 3 into the semicylindrical bodies 3. An inner frame cylinder 12 in which two semicylindrical bodies 11 are paired and corresponding surfaces of axial edge surfaces 13 are opposed to each other is housed in the outer frame cylinder 2. A cylinder 14 for separation obtained by forming a flat plate with peelability and elasticity against deformation into a cylindrical shape is housed in the inner frame cylinder 12. Further, the inside of the cylinder 14 for separation serves as a test piece forming space in which a mixture of inorganic wastes, soil, and cement is filled and compressed to form a test piece. |
