GB/T 749-2008 《Test method for determining capability of resisting sulfate corrode of cement》 Related products

GB/T 749 - 2008 specifies the test method for cement resistance to sulfate erosion. It specifies the test principle and tests the cement performance by simulating the sulfate environment. The standard specifies the required equipment, such as the temperature and Humidity control accuracy of the curing box. Standardize the production of cement specimens, including size and molding process. During the test, determine the concentration of sulfate solution, soaking conditions and test period. The resistance of cement to sulfate erosion is judged according to the strength change of the specimen and other indicators. The standard provides a basis for evaluating the durability of cement in sulfate-containing media, and helps to select suitable cement for construction, water conservancy and other projects to ensure long-term stable operation of the project.
