The present invention relates to a self-leveling composition for floor toppings, characterized in that it is based on Portland cement or on cement mix CM II or CM III, and in that it further comprises at least sand, water and at least one plasticizer which is a water-soluble or water-dispersible organic compound (I) containing at least one aminodi(alkylenephosphonic) group and at least one polyoxyalkyl chain, or at least one salt of compound (I).

Cement-Based Self-Leveling Composition

Setting and hardening accelerating agent for siliceous hydraulic binders

Process for protecting articles from shock comprising encasing such articles in a plurality of molded blocks of a composition capable of progressively and irreversibly deforming in response to such shocks, said composition comprising cellulosic fibers dispersed in a matrix of at least one non-hydrated hydraulic binder, wherein from 2.5 to 75 parts by weight of the cellulosic fibers are dispersed per 100 parts by weight of said binder, said composition, upon curing and drying, exhibiting a density between 0.15 and 0.60.
