If aggregate size is less than 38mm the cube mould are design 150*150mm.

Answer / rethina kumar

1.cube mold size is 150x150x150mm 
2.cross section of mold should be standard 150x150mm, depth of mold may vary. this is due compression testing machine has been disgned for 150mmx150mm cross section size. that is reason mold size is 150mmx150mm we are using, and that is not necessary to use this standard mold.
3.if you would like change mold size you need to design compression testing machine for corresponding mold size.
