Abstract

En jernkompleksdannende, pH-nøy-tral til basisk forbindelse blir an-vendt som aktivator, spesielt for å forkorte bindetidene og for å øke tid-lig- og langtidsfasthetene, i et som tilsetningsmiddel oppløselig salt av det kullsyreholdige hydrauliske bindemiddel. Bindemidlets ferrittandel bør utgjøre minst 4 vekt%. Den jernkompleksdannende forbindelse skal tilblan-des bindemidlet i tørr tilstand. Et hydraulisk bindemiddel ifølge oppfin-nelsen inneholder fortrinnsvis minst 3 mmol% av en jernkompleksdannende forbindelse og en karbonatdonor i et mol-forhold mellom 0,3 og 4, basert på den jernkompleksdannende forbindelse.An iron complex-forming, pH-neutral to basic compound is used as an activator, in particular to shorten the bonding times and to increase the early and long-term strengths, in an additive-soluble salt of the carbonated hydraulic binder. The ferrite content of the binder should be at least 4% by weight. The iron complexing compound must be mixed with the binder in the dry state. A hydraulic binder according to the invention preferably contains at least 3 mmol% of an iron complexing compound and a carbonate donor in a molar ratio between 0.3 and 4, based on the iron complexing compound.
