Title
(EN) IRRADIATED POLYMERS IN BUILDING MATERIALS FOR CONCRETE FORMING
(FR) POLYMÈRES IRRADIÉS DANS DES MATÉRIAUX DE CONSTRUCTION DESTINÉS À LA FORMATION DE BÉTON
Abstract
(EN)
Building materials include particles of a polymer in an irradiated form, cement, sand, and gravel. In concrete formed from these components, the polymer in the irradiated form may contribute to maintaining or improving structural characteristics, such as compressive strength, ductility, durability, or a combination thereof, as compared to concrete formed without the use of a polymer or as compared to concrete formed without the use of a polymer in an irradiated form. Further, or instead, the particles of the polymer that are irradiated may be from one or more of a variety of ubiquitous sources, such as recycled material. Thus, for example, the concrete formed using particles of the polymer in the irradiated form according to the present disclosure may facilitate achieving target structural performance while, additionally or alternatively, reducing emissions of greenhouse gases or other pollutants, as compared to concrete formed without a polymer.
(FR)
L’invention concerne des matériaux de construction comprenant des particules d'un polymère sous forme irradiée, du ciment, du sable et du gravier. Dans le béton formé à partir de ces constituants, le polymère sous forme irradiée peut contribuer au maintien ou à l’amélioration de caractéristiques structurales, telles que la résistance à la compression, la ductilité et la durabilité, ou une de leurs combinaisons, par rapport au béton formé sans avoir recours à un polymère ou par rapport au béton formé sans avoir recours à un polymère sous forme irradiée. En outre, ou à la place, les particules du polymère qui sont irradiées peuvent provenir d'une ou de plusieurs sources répandues différentes, par exemple un matériau recyclé. Ainsi, par exemple, le béton formé à l'aide de particules du polymère sous forme irradiée, selon la présente invention, peut favoriser l'obtention d'une performance structurale cible et ce, en outre ou en variante, tout en réduisant les émissions de gaz à effet de serre ou d'autres polluants, par comparaison avec un béton formé sans polymère.
