The determination of cold crushing strength (CCS) is also highly important in case of refractory insulating bricks where bricks have to be porous as well as strong. For the measurement of the CCS, according to EN 993-5, a steadily increasing compressive load is applied to the refractory test piece by a compressive machine until the test piece

Cold crushing strength – It is a measure of the mechanical strength of the refractory brick. In furnaces, cold crushing strength is of importance, because of bricks with high crushing strength is more resistant to impact from rods or during removal of slag than a brick with a low cold crushing strength.

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: The cold crushing strength is the resistance of the refractory to crushing, which mostly happens during transport. It only has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. Other indicators used are bulk density and porosity.

Cold crushing strength – The cold crushing strength determines the ability to withstand the rigorous of transport and handling before the installation of refractories in the furnace. It can be seen as a useful indicator to the adequacy of firing and abrasion resistance in consonance with other properties such as bulk density and porosity.

This reveals how well a refractory material can sustain installation loads or resist the rigors of transportation, whereas the hot compressive strength indicates how well it will operate at high temperatures. A compression test is used to determine it. It is used to ensure that refractory brick does not crush when subjected to high pressures.
