1. A method comprising:
applying a mineral binder composition to a substrate for jointing and/or grouting of porous materials, cementing, levelling, repairing cementitious materials, or as a render; and
setting and/or curing the mineral binder composition, wherein the setting and/or curing of the mineral binder composition takes place at temperatures <15° C.,
wherein the mineral binder composition comprises
a) a mineral binder B,
b) at least one free-radical initiator I,
c) at least one catalyst C for the at least one free-radical initiator I,
d) optionally aggregates,
e) optionally additives selected from the group consisting of plasticizers, superplasticizers, rheology modifiers, accelerators, retarders, air-entrainers, de-aerating agents, corrosion inhibitors, fibers, synthetic organic polymers, expansion producing additives, pigments, strength enhancers, waterproofing additives, alkali-aggregate reaction inhibitors, chromate reducers, anti-freeze agents, and anti-microbial agents, and
wherein the mineral binder composition comprises <5.0 w %, based on a total dry weight of the mineral binder composition, of radically polymerizable monomers or polyisocyanates.
