Mould for thin sample casting

autorzy: Dragana Janković

In order to investigate shrinkage and micro-cracking of samples (D = 1 mm) made of concrete and other cementitios materials, in the electron microscope (ESEM), in the sample early age (min 2-3 days old), when samples are still soft and breakable, mould is created. The mould is made of stainless steel. It consists of the bottom plate, the thin (2 mm thick) surface plates, which are fixed to the bottom plate with screws. The thickness of surface plates determines the thickness of casted samples. For experiments in ESEM, where a large number of thin (10 x 10 x 2 mm) samples is needed, the constructed mould contains 10 cells. If needed, the shape and size of casted samples can vary by removing a certain number of plates. The mould is multipurpose, very easy to handle and maintain.
