GB/T 34218-2025 is a revision of the 2017 edition standard, which specifies the test method for determining the compressive strength of refractory materials at high temperatures. After heating the specimen to a specified temperature in a furnace and maintaining it at that temperature, an axial pressure is applied until failure occurs, and its high-temperature compressive strength is calculated. This is a key indicator for evaluating the high-temperature load-bearing capacity of refractory products.
