Cementitious binders containing pozzolanic materials
A cementitious composition including: a binder containing (a) 60-94%, by weight, of at least one pozzolanic material; (b) at least 0.5% calcium sulfoaluminate (CSA), by weight; (c) 1.2-11% by weight, expressed as SO3, of at least one inorganic sulfate selected from the group of sulfates consisting of a calcium sulfate hemihydrate, an anhydrous calcium sulfate, a calcium sulfate dihydrate, a sodium sulfate, and a sodium calcium sulfate; and (d) a total sulfate content of at least 3%, by weight, expressed as SO3, the cementitious composition including, at most, 3% natural lime, the cementitious composition including, at most, 10% alumina cement, the contents of the composition being calculated on a dry, aggregateless basis.
