    摘要: The present invention relates to ballast which have a high stability and a long service life and to a process for the production of ballast. These ballast are suitable for railway track laying and road construction and dike systems used for example in costal protection. These ballast comprise ballast stones and polyurethane foams based on a reaction mixture of selected polyisocyanates and selected compounds with isocyanate-reactive groups.

    摘要: The present invention relates to improved gel masses prepared from a reaction mixture of NCO prepolymers and selected compounds containing groups reactive towards isocyanate groups. This invention is also directed to a process for the production of these gel masses and to the production of pressure-distributing elements comprising these gel masses.
