Abstract

The design of a stainless-steel cylindrical tool for manual grinding and polishing of cement-based thin sample (two cylinders one within the other, connected by the movable threaded holder with a plate, that passes through the middle) enables very precise removal of sample layers to its thickness of 1-mm ( 1/32 inch) and less. The squared, young aged sample rests on the circular plate on a holder, that can be slowly and safely rotated during thin layer removal, to obtain a smooth and flat sample surface, which can produce sharp digital images in ESEM, necessary for detailed and accurate image analysis. The cylindrical tool can be reassembled. It is reusable, easy to maintain and clean. Its design is practical since inner cylinder can be replaced if damaged, with the identically designed inner cylinder or with differently designed inner cylinder adjusted to another sample size.
