Verfahren zum Verbinden von organischen Kunststoffen mit mineralischen Stoffen oder anorganischen hydraulischen Bindemitteln

摘要

Concrete compositions are prepared from cement, water, an optional aggregate and particles of expanded styrene polymers whose surfaces are coated with an organosiloxanol of formula where n is an integer from 1-250, R is a C1-C6 alkyl or alkenyl group or an aryl group. The styrene may be copolymerized with acrylonitrile, acrylic or methacrylic esters of C1-C8 alcohols, N-vinyl compounds, e.g. N-vinyl carbazol and divinylbenzene. Aggregates specified are sand, pumice, vermiculite and asbestos.
