Description
This dataset is a market dataset. Each market represents the consumption mix of a product within a specific geographical region, taking into account the process of transport to the consumer as well as the losses in this process. This activity represents the supply of Portland cement clinker for the cement manufacturing consumption activity. The data are based on national standards and publicly available literature.
Activity Description
This data set is a market activity data set, covering the average transportation distance of China’s domestic cement clinker market and the average transportation distance from overseas ports to domestic ports. Domestic transportation is mainly carried out by railway, waterway, and road; overseas, sea transportation is mainly used. Average cement clinker transport losses are also included. The data sources are mainly the China Statistical Yearbook and the study on the peak pathway of carbon dioxide emissions in China's cement industry, Research of Environmental Sciences, 35(2): 10, and Pub.151 "Distances Between Ports", National Geospatial-Intelligence Agency (NGA), 2024.
Process Description
Portland cement clinker is a granular solid formed by mixing calcareous raw materials, clay raw materials, and a small amount of corrective raw materials in appropriate proportions, calcining at high temperatures until partially melted, and then cooling. It is the main raw material for cement production, and can be ground together with an appropriate amount of gypsum and mixed materials to prepare various types of cement.

Technology comment
Cement clinker is produced using a new dry rotary kiln process, which is the core technology of modern cement production. It uses a suspended preheater (SP) or precalciner (NSP) combined with rotary kiln calcination to achieve efficient, low-consumption and low-emission cement clinker production.
