  • Patent number: 11878942
    Abstract: A cementitious composition with accelerated curing at low temperatures particularly at temperatures <5° C., especially at temperatures <0° C. The cementitious composition consists of 2 components with a first component A including at least one ordinary Portland cement, at least one cement selected from calcium aluminate cement and/or calcium sulfoaluminate cement, a powder P, selected from the group consisting of carbonates or hydrogen carbonates of alkali and/or alkaline earth metals, optionally aggregates, optionally other additives and a second component B comprising at least one accelerator, an anti-freeze agent, water, and optionally other additives. The composition shows increased development of compressive strength, maintain good workability, and have particularly low shrinkage, also when cured at temperatures <5° C., especially <0° C., and as low as ?10° C.

  • Patent number: 11845695
    Abstract: An additive for mineral binder composition, in particular accelerators for mineral binder compositions, in particular cementitious binder compositions. The accelerator includes 35 to 99.7 w % of at least one mineral filler F with a particle size D50<5 ?m, preferably <4 ?m, most preferred <3.5 ?m, 0.3 to 65 w % of a sodium aluminate SA, and 0 to 45 w % of at least one other inorganic compound I selected from the group consisting of calcium aluminate cements and/or sulfates of alkali or alkaline earth metals. Further, corresponding mineral binder compositions as well as uses and processes, including the acceleration of setting and curing of mineral binder compositions at low temperatures.

  • Publication number: 20220242789
    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.
