Abstract: The invention relates to the use of a multi-component composition comprising A) a polyol component (A) comprising at least one polyol and water, B) a hardener component (B) comprising at least one polyisocyanate, and C) a solid component (C) comprising a hydraulic binder and one or more aggregates, as an early water resistant construction or repair material for constructing, repairing or refurbishing component parts, wherein the mixed and applied multi-component composition is immersed in water not later than 8 hours, preferably not later than 2 h, after application. The use as an early water resistant construction or repair material is especially suitable for component parts, which are in contact with water during operation such as offshore wind energy plants or water retaining systems, e.g. pipelines.

Abstract: A reactive resin compositions include at least one polymerizable system, at least one volatile organic compound, cyclodextrin, and optionally at least one curing agent, which are obtainable by mixing the polymerizable system with the volatile organic compound and the cyclodextrin and storing the mixture for a period of time until an equilibrium is established between the volatile organic compound and the cyclodextrin. By adding cyclodextrin it is possible to reduce the VOC emissions of corresponding reactive resin compositions significantly, the observed effect being greater than would be expected on the basis of the molar ratio of the volatile organic compound to the cyclodextrin. The reactive resin composition can thus be used advantageously in applications such as coatings and/or sealants, in which the evaporation of organic compounds should be avoided.
