摘要:
The present invention relates to a method for inerting non-bloating clays in at least one mineral component intended for the preparation of a hydraulic composition, which includes adding, to the hydraulic composition, to the mineral component, or to one of the other components of the hydraulic composition, an organic molecule having a cationic charge density of strictly less than 0.5 meq/g and including at least two atoms, each of which is capable of forming at least one hydrogen bond.
摘要:
The invention relates to an adjuvant for a hydraulic binder composition comprising at least one cationic polymer and at least one anionic polymer, wherein at least one of these polymers has a comb-structure, in which the anionic polymer/cationic polymer mass ratio is between 99.9/0.1 and 60/40. It also relates to a process for preparing said composition and to its uses as a plasticizer.
摘要:
The invention concerns a composition useful for inerting clays in hydraulic compositions, comprising at least 50 wt. % of a cationic polymer having a cationic charge density more than 0.5 meq/g and an intrinsic viscosity less than 1dl/g, as active substance.
摘要:
The invention concerns a method for inerting clays in sand intended for preparing hydraulic compositions, comprising a step which consists in adding to the composition or one of its constituents a cationic polymer having a cationic charge density more than 0.5 meq/g and an intrinsic viscosity less than 1 dg/l.
摘要:
The present invention relates to a mixture including at least one hydraulic and/or pozzolan material and at least one water-soluble cationic polymer, said cationic polymer having a cationic charge density higher than 0.5 meq/g and an intrinsic viscosity lower than 1 dl/g, wherein said hydraulic and/or pozzolan material is not clinker, limestone, gypsum, calcium sulphate, anhydrous calcium sulphate, semi-hydrated calcium sulphate, plaster, or lime. The invention also relates to a hydraulic composition and to a cured object including said mixture.
