Because static load is caused below normal temperature condition,the problem that fireproof data appears is rarely. Because this undertakes this kind of experiment is to consider indirect ground normally,examine other property, be like wearability. Be like compression intensity again under 1000 pounds / inch the chromic magnesia brick of 2, faint from a place in workshop of a fusion merely another place appears easily edge or drop horn, so flimsy brick can rupture even when assemble and unassemble, create serious waste thereby. The indirect import of numerical value of intensity of normal temperature compression but illustrate is as follows:
1, to argillaceous brick, intensity of normal temperature compression is low show agglomeration quality is bad, suggest to need to examine to burn midline change again further.
2, intensity of particularly low normal temperature compression, make clear to chromic magnesia brick oxidizes in what appear alternately and expand easily in reducing atmosphere, think to already discovered, the meeting when such brick repeats to calcine damages further, also can produce similar problem when use.
The direction of the size of test block and pressurization is made clear in test report, because although be in,turn inside have slight statified also can be opposite test result is affected apparently again. Turn to a batch when appoint when doing compression to experiment, want to undertake for many times, so that notice its numeric distributinging limits.
