CUBE SPECIMENS 2.1.1 2.1.1.1 2.1.1.2 2.1.1.3 2.1.1.4 Equipment required for making cube specimens Moulds iMoulds are i n the form of a cube, made of steel or cast iron. Their inner surfaces are lapped. Their bases are made of st
4、eel with hardness not less than 95 according to Rockwell B. The mould consists of four sides and a base, that can be mounted and dismounted. When assembled, the contact surfaces shall be water tight. The nominal lengths fo the cube edses are 100, 150 or 200 mm. The parts of the mould shall have adeq
5、uate thickness to prevent distortion during use. The thickness of the bottom base must not be less than 10 mm for cubes 100, 150 and 200 mm. The thickness of the sides must not be less than the values in Table 1. Table i The moulds must be easily dismounted, assembled and fixed. The means of fixatio
6、n must withstand repetitive use without damage. nec The sides of the mould, together with the base form a fixed unit that dc, distort while the specimen is being prepared. The sides can not be. moved except for dismounting. -,-,- 2.1.15 Dimensions 2.1.1.5.1 Cubes with inner nominal dimensions of 150
