Abstract
Mineral binder compositions with accelerated setting and/or curing including a mineral binder, at least one free-radical initiator, and at least one catalyst for the at least one free-radical initiator. The mineral binder compositions accelerated setting and hardening and are especially useful for applications at low temperatures and even below 0° C.
Claims12
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.

A multi-component composition consisting of
- a) a first component K1 comprising
- 1) 10-75 w % of a mineral binder B, and
- 2) 0.01-10.0 w % of the at least one free-radical initiator I,
- b) a second component K2 comprising
- 1) 0.05-10.0 w % of the at least one catalyst C for the at least one free-radical initiator I, and
- 2) water,
- each based on a total weight of the multi-component composition and wherein the multi-component composition comprises <5.0 w %, based on a total dry weight of the multi-component composition, of radically polymerizable monomers or polyisocyanates.
