The invention concerns the use of sols of non-metals or metals, their oxides, hydroxides, oxihydrates and/or polymers thereof (e.g. hetero-polyacids) for reducing proneness to cracking during hardening of unhardened binder suspensions (such as fresh concrete, ready-mix) and for secondary treatment of binder suspensions (e.g. concrete) which have hardened.
L'invention concerne l'utilisation de sols de métaux et de non-métaux, leurs oxydes, hydroxydes, oxyhydrates et/ou leurs polymères (par ex. les hétéropolyacides) pour réduire la tendance aux fissures lors du durcissement de suspensions de liants non durcies (par ex. de béton frais, béton prêt à l'emploi) et pour le traitement ultérieur de suspensions de liants déjà durcies (par ex. de béton).
