Beschreibung
Zusammenfassung:	A three component composition consisting of a polyol component (A) including at least two polyols, one with high, one with low molecular weight and water, a polyisocyanate component (B) including a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2.5, or a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2 and at least one further polyol with an amount of between 1% and 30% based on the weight of the polyisocyanate component (B), wherein the MDI product and the polyol have reacted at least partially, and a powder component (C) including at least one hydraulic binder, preferably cement and/or calcined paper sludge, preferably a calcium compound selected from calcium hydroxide and/or calcium oxide, and optionally one or more aggregates.
