Title
(EN) SELF-COMPACTING CEMENTITIOUS COMPOSITE
(FR) MATERIAUX COMPOSITES A BASE DE CIMENT ELABORES PAR AUTOCOMPACTAGE
Abstract
(EN) Short fiber-reinforced engineering cementitious composites which are self-compacting, can be prepared by adding hydrophilic polymer fibers to a cement composition containing polymeric thickener and superplasticizer. The compositions are exceptionally ductile and exhibit many of the physical characteristics previously available only with hydrophobic high performance polyethylene fibers.
(FR) L'invention porte sur des matériaux composites à base de ciment élaborés au moyen de fibres de renforcement courtes qui s'autocompactent. Pour préparer ces matériaux composites, on ajoute des fibres polymères hydrophiles à une composition de ciment contenant un épaississant polymère et un superplastifiant. Les compositions sont exceptionnellement ductiles et présentent de nombreuses caractéristiques physiques qu'elles possédaient déjà uniquement avec les fibres de polyéthylène, haute performance, hydrophiles.
