Oct 03, 2013 Cold crushing strength – It is a measure of the mechanical strength of the refractory brick. In furnaces, cold crushing strength (CCS) is of importance, because of bricks with high crushing strength is more resistant to impact from rods or during removal of …
Cold crushing strength: Cold crushing strength is the amount of load that the clay/refractory material could withstand after it has been fired to a temperature of 1200oC. In determining the cold crushing strength (CCS) of the clay/refractory samples, cubicle specimens were made from the clay/refractory samples.
Cold crushing strength, commonly used to characterise the mechanical strength of refractory materials, is determined according to standards in different parameters of the test.
