CEMENTITIOUS COMPOSITION
The present application relates to a cementitious composition suitable to be applied to an object via a nozzle. The composition comprises a) 15-90% by weight of a cementitious binder, b) 0.02-3% by weight of an ettringite formation controller, c) 0.15-10% by weight of a magnesium salt accelerator and d) 0.02-2% by weight of a polyhydroxy compound A, and/or salts or esters thereof, wherein the polyhydroxy compound A is selected from polyalcohols with a carbon to oxygen ratio of C/O≥1 and mixtures 0 thereof, based on the total dry weight of the composition. Further a process for applying the composition onto a surface and a hardened structure obtained by the process is disclosed.
