9 Claims

1. A mineral binder composition comprising:

a mineral binder comprising 36-65 weight-% of slag and 35-64 weight-% of Portland cement, based on the weight of the mineral binder,

an activator for the hydration of the slag comprising calcium hydroxide and

a co-activator comprising at least one salt selected from the group consisting of lithium carbonate, lithium sulfate and sodium carbonate,

wherein the activator is present in an amount in a range of 0.5-3.0 weight-% based on the weight of the mineral binder,

wherein the co-activator is present in an amount in a range of 0.16-0.8 weight-% based on the weight of the mineral binder, and

wherein a weight-ratio of activator to co-activator is 10:1 to 1.1:1.
