Beschreibung
Zusammenfassung:	The invention concerns the use of expanded polymer particles for making lightweight-aggregate building materials such as lightweight-aggregate concrete and mortar, characterised in that it consists in using an aggregate containing expanded and hydrophobic organic polymer particles with residual water content not more than 5 % p/p, said particles capable, if required, of acting as carriers for concrete and mortar additives. The invention also concerns as novel industrial products aggregates containing said hydrophobic organic polymer particles.
