The University of Kentucky’s Center for Applied Energy Research, in collaboration with the College of Material Science and Engineering in Nanjing and the Asian Coal Ash Association, have published a paper in response to a collection of twenty coal ash samples from Shanxi Province, China.
The chemistry of this ash showed that the ingredients showed high amounts of sulfate and alumina. This specific concentration of material is optimal for highly durable cement aggregates. The ash was collected from the Shentou Power plant in Shouzhou city, Shanxi Province China, where the Asian Coal Ash Association hosts its annual Coal Ash Asia conference.
The presence of these materials not only allows for stronger cement than regular Portland, but for a lower carbon footprint during production and application.
