If the slag level rose too high, the tap arch, a door in the bottom of the furnace, could be opened and liquid slag drained (left). The liquid slag flows like water. Solidified slag (right) from archaeological sites provides a great deal of information about the smelting process in the Viking age.
This paper aims to present a digital image processing (DIP) technique to evaluate aggregates' resistance to polishing and degradation, along with the use of the Los Angeles abrasion equipment. The aggregate image measurement system was used to analyse the aggregates mainly not only with respect to angularity and surface texture, but also with ...
