Abstract: This paper outlines the research and development process, as well as the production practice of a specialized cement. Despite the less-than-ideal quality of high-silica, low-calcium limestone sourced from our own mines, significant improvements were made through the meticulous selection of raw and fuel materials, refining the raw meal formulation, enhancing the quality control of cement clinker, and improving the operation of calcination control. These efforts led to the development and production of a new type of cement clinker with approximately 0.2% alkali content and a silica ratio of about 3.50. This low-alkali, high-silica, and high sulfate-resistant cement clinker fulfills the construction requirements for environments prone to sulfate erosion, freeze-thaw cycles, and alternating dry-wet conditions, such as harbors, water conservancy projects, and underground engineering.
