Differences and uses between sulphoaluminate cement and portland cement

The main difference is that the setting time is different. Generally, the setting time of sulphoaluminate cement is 1 to 6 minutes, while that of ordinary cement is 6 to 3 minutes. The strength development time is different. The strength of sulphoaluminate cement is generally above 35 MPa a day, while that of ordinary cement is not required (too low). Sulphur-aluminum cement is mainly used in GRC cement products or emergency repair and construction projects, as well as the production of special engineering materials, not to mention ordinary cement
