ActiveTest method for autoclave expansion of cement
水泥压蒸安定性试验方法
Application Summary AI generated
This standard specifies the test method for determining the autoclave expansion of cement, which evaluates the soundness of cement by measuring its volume stability under high-pressure steam conditions. It is applied in the construction industry for quality control of cement used in concrete structures, particularly to detect delayed expansion caused by free lime or magnesia that could lead to cracking. The test is critical for ensuring the long-term durability of cement in large-scale infrastructure projects like bridges, dams, and high-rise buildings.
