Cement is an important component of concrete and has a decisive impact on the properties of freshly mixed concrete slurry and the properties after hardening. Over the past half century, although there have been no fundamental changes in the basic composition and performance of general Portland cement (i.e. Portland cement in China), certain characteristics such as early strength, workability of mortar, and adaptability to other components and process requirements of concrete have greatly developed. Many specialized cements have emerged, and some of their characteristics have been optimized to adapt to specific fields of use, such as low heat cement, jet cement, ultrafine cement, etc. Although these specialized cement quantities are not large, they have played a significant role in promoting the development and application of new cement technologies, and have also made it possible to implement some new construction methods. In the future, there will be greater progress in the variety and characteristics of cement, which can better meet the needs of concrete technology and become high-performance, low-cost, and environmentally friendly industrial bonding materials. The main problems with cement quality in China include many aspects. Here, we will only discuss the main aspects that have a significant gap compared to the international advanced level. 2.1 Low quantity of high-grade cement and relatively low maximum strength
