Calcium sulfate based composition incorporating sulfo-aluminous clinker for the preparation of a hydraulic binder for the subsequent preparation of concrete based construction materials

摘要

Calcium sulfate based composition incorporates 20 to 60 % by weight of a sulfo-aluminous clinker. The clinker includes at least 50 % by weight of yeelimite Independent claims are also included for : (a) a hydraulic binder made from this composition; (b) a construction material using this composition.
