3 Terms and definitions
GB/T 18930 as defined in the following terms and definitions apply to this document.
3.1
High temperature compressive strength compressivestrengthatelevatedtemperature
Under high temperature, under the specified conditions of pressure, the sample crushing or its high degree of compression of the original (90 ± 1)%, the sample unit area can bear
Under pressure.
4 principle
Heating the sample at the specified heating rate to the test temperature and keeping the temperature of the sample uniform, then applying the sample at the specified loading rate
Load until crushed or highly compressed to the original size of (90 ± 1)%, record the maximum load. According to the specimen to withstand the maximum load and
Compressive cross-sectional area to calculate the high temperature compressive strength.
5 device
5.1 heating device, heating device so that the sample temperature constant test temperature within ± 10 ℃. Heating device should be able to protect the atmosphere or air
Gas in protective gas at the required heating rate heating, heat, until the end of the test.
5.2 loading device, loading device should meet the following conditions.
a) sufficient force to destroy the specimen;
b) The sample can be loaded at a predetermined rate uniform load, and is equipped with a sample height measurement device and the real-time measurement of the load
