Your Global Partner in CSA & CAC Solutions
Calcium Sulphoaluminate Cement Series
The CSA Series features rapid-setting, shrinkage-compensated cementitious materials based on calcium sulphoaluminate chemistry. It includes CSA binder, road repair compounds, and leak sealing agents—widely applied in infrastructure rehabilitation, self-leveling systems, grouting, and other fast-track construction scenarios.
Calcium Sulphoaluminate Ground Clinker for High-Performance Cementitious Systems
CSA expansive agent is a high-efficiency shrinkage-compensating material formulated by blending carefully selected natural anhydrite with a specially manufactured clinker composed primarily of calcium sulphoaluminate and free lime (CaO). It is designed to be used in combination with ordinary Portland cement.

Calcium Aluminate Cement Series
The CA Series comprises high-alumina cements known for their excellent thermal stability, early strength, and chemical resistance. Typical applications include refractory castables, corrosion-resistant concrete, industrial flooring, and structures exposed to aggressive environments.
CA40
CA 40 is a hydraulic binder with an alumina content of approximately 40%. Composed primarily of calcium aluminates, it serves as an outstanding binding agent for refractory applications. The high monocalcium aluminate concentration in CA 40 endows refractory concrete with excellent mechanical strength. However, its iron oxide content makes it unsuitable for use in refractory concretes where iron oxide cannot be tolerated, such as in reducing atmospheres.
CA50
CA50 is a high-performance calcium aluminate cement developed for refractory applications requiring thermal stability and corrosion resistance. Produced by sintering high-purity bauxite and limestone, it is primarily composed of monocalcium aluminate (CaO·Al₂O₃) and features rapid strength development and reliable performance under high-temperature and chemically aggressive environments. The CA50 series includes A600, A700, and A900 grades, each designed to meet specific setting and strength profiles for various castable systems.
CA70
CA70 is a high-purity calcium aluminate cement engineered for superior refractory performance, featuring a significantly elevated alumina content. Composed predominantly of monocalcium aluminate (CaO·Al₂O₃, or CA), it delivers exceptional mechanical strength, rapid hardening, and outstanding resistance to high temperatures. Produced through a precision sintering process in a rotary kiln using select bauxite and limestone, CA70 is tailored for advanced refractory applications where durability and thermal stability are paramount. Its refined formulation ensures reliable performance in extreme environments, making it a cornerstone for high-performance castables.
CA80
CA80 is an ultra-high purity calcium aluminate cement engineered for the most demanding refractory applications, boasting an exceptionally high alumina content. Dominated by monocalcium aluminate (CaO·Al₂O₃, or CA) and dicalcium aluminate (CaO·2Al₂O₃, or CA₂), it offers unparalleled mechanical strength, thermal stability, and resistance to extreme conditions. Produced through a highly controlled rotary kiln sintering process using premium bauxite and limestone, CA80 is the ultimate choice for advanced refractory systems requiring maximum refractoriness and durability. Its refined composition ensures top-tier performance in critical high-temperature environments.
