Bayer red mud has no active components such as 2CaOSiO2, high iron content and poor corrosion resistance, so it is difficult to be directly used in building materials industry.
The red mud from Bayer process has low content of β-C2S and other active components, high alkali content and poor corrosion resistance, so it is difficult to be directly applied to building materials, which seriously restricts the resource utilization process of red mud from Bayer process.
