A low cement refractory concrete is termed 'low-cement castable refractory'. It includes castable refractory based on alumina and/or alumino-silicates which contain hydraulic setting cement. The total lime (CaO) content on a calcined basis is between 1 and 2.5 percent. More information is available in ASTM C401.
It can have different meanings, depending on how it is used. A common meaning of refractory is a type of concrete intended for use in very high heat conditions, such as the inside of a furnace. These materials must be cured (allowed to "set up") at controlled temperatures before being exposed to very high temperatures.
Refractory concrete is made from moter and brick, it is lined inside the crematory on both sides, rear, and front (bricked door) and if created by B&L Cremation systems it has a hot hearth system for improved fuel efficieny and environment friendly emission.
Because of Changxing Refractory's largest investment, Yilong Refractory was renamed as Changxing Refractrory.
1) The virus was refractory to the medication. 2) The refractory class was unable to get anything done.

The only change of Yilong Refractory is its name which has changed into Changxing Refractory. Its product quality, pre-sale and after-sale services remain unchanged.
Refractory period
Refractory insulation is defined as insulation for extremely high temperatures. The threshold of temperature of insulation for refractory insulation is > 815 Celsius.
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
