The present invention relates to a chemically bonded ceramic material based on 3CaO•Al 2 O 3 (also denoted as C 3 A) and its use in applications wherein the ambient temperature during hydration is above 25°C. The main binder system forms a chemically bonded ceramic upon hydration thereof and is based onpowdered calcium aluminate, and may optionally contain minor amounts of other phases ofcalcium aluminate and/or calcium silicate. An optimal second binder system is a crosslinking organic binder system which provides for initial crosslinking of the freshly mixed paste forming the biomaterial. The material also comprises inert filler particles. The invention relates to a powdered composition for preparing the inventive chemically bonded ceramic material, and a paste from which the material is formed, as well as a kit comprising the powdered composition and liquid, as well as methods of using the material as a biomaterial in small volume applications, and the use of the general material as a construction material.
