SECAR® 41 is a fused hydraulic cement with a high content of monocalcium aluminate to give strong hydraulic activity and impart excellent mechanical properties to conventional concretes. Available in Europe and the North American Markets it is ideally suited to refractory applications where rapid hardening, resistance to abrasion and mechanical shock are critical. Its rheological properties are well adapted to all types of placing methods such as casting and gunning.
