| 摘要 |
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. |
