Abstract

The present invention relates to a method of manufacturing hydrophobized recycled concrete aggregates, which are recycled concrete aggregates (RCA) surface modified with one or more silanizing agents selected from organosilanes, linear, branched or cyclic organosiloxane oligomers, polyorganosiloxanes or combinations thereof, and the hydrophobized recycled concrete aggregates obtained by this method.The hydrophobized recycled concrete aggregates of the invention are suitable as aggregates for cementitious compositions exhibiting a reduced water demand as compared to cementitious compositions including untreated recycled concrete aggregates.
