Title (EN) USE OF HYDROPHOBIC ORGANIC POLYMER PARTICLES FOR MAKING LIGHTWEIGHT-AGGREGATE CONCRETE AND MORTAR
(FR) UTILISATION DE PARTICULES DE POLYMERE ORGANIQUE HYDROPHOBE DANS LA FABRICATION DE BETONS ET MORTIERS ALLEGES
Abstract:
(EN) 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.
(FR) La présente invention a trait à une utilisation de particules de polymère organique expansé dans la fabrication de matériaux de construction allégés du type bétons et mortiers allégés, caractérisée en ce que l'on fait appel à un granulat comprenant des particules de polymère organique expansé et hydrophobe ayant une teneur en eau résiduelle inférieure ou égale à 5 % p/p, lesdites particules pouvant, le cas échéant, intervenir en tant que supports pour additifs de bétons et mortiers. Elle concerne également en tant que produits industriels nouveaux les granulats comprenant lesdites particules de polymère organique hydrophobe.
