Abstract
Colloids of non-metals or metals, their oxides, hydroxides, oxihydrates and/or polymers (such as, e.g., heteropolyacids) are used in a method for reducing the susceptibility to fissuring in the curing of non-cured binder suspensions (such as, e.g., unset concrete, ready-mix) and for aftertreating already cured binder suspensions (such as, e.g., concrete).
