Calcium sulfoaluminate cement (CSA cement) was developed in China in the 1970s. Designed by the China Building Materials Academy (CBMA), they were intended for the manufacturing of self-stress concrete pipes due to their swelling properties.

Calcium Sulfoaluminate cement (CSA Cement for short), was developed in China. This special cement distinguishes itself from Portland cement by a high-speed bonding, fast strength development, and a shrinkage reduction.

Portland cement concrete can be accelerated with organic additives that can be expensive, have a short shelf life and require additional handling equipment to keep the material in suspension on a jobsite. Calcium sulfoaluminate (CSA) cement has recently emerged as an innovative alternative to Portland cement for tunneling

In summary, Calcium Sulfoaluminate Cement (CSA) presents a promising and eco-friendly alternative to traditional cement types such as Ordinary Portland Cement (OPC) and Calcium Aluminate Cement (CAC).
