Abstract
The invention relates to a mineral, hydraulic binder for producing concrete or mortars or cement suspensions, based on at least one cement. The cement comprises clinker phases such as, CS, CS, CA, and CAF, which on reaction with water form hydrate phases that cure to form hardened cement. The cement displays a delay phase after mixing with water of some hours, e.g. from 4 to 8 hours, during which time no appreciable curing reaction takes place. The binder further comprises at least one finely divided SiOcomponent and at least one finely divided CaO component, which react with make-up water during the delay phase to form calcium silicate hydrate phases that cure as a result of a pozzolanic reaction and produce early strength.
