Title (EN) MANUFACTURING CONCRETE CONSTRUCTION ELEMENTS CONTAINING CRUSHED SEA-SHELLS, WHICH ARE SELF-DRAINING AND MECHANICALLY STRONG
(FR) FABRICATION D'ÉLÉMENTS DE CONSTRUCTION EN BÉTON CONTENANT DES COQUILLAGES CONCASSÉS, AUTO DRAINANTS ET MÉCANIQUEMENT RÉSISTANTS
Abstract: front page image
(EN)The invention relates to the production of concrete construction elements that are pervious to water and mechanically strong. For this purpose, the invention proposes adding, to a concrete composition containing cement and other ingredients such as aggregates 1, substantially flat elements 4, in particular crushed sea-shell products which, by impeding the tight interlocking of the other ingredients such as the aggregates 1, create porosities that promote water perviousness. The invention can be used for the production of paving stones, slabs or coatings poured on site, in particular for car parks, paths or roadways, which are self-draining and enable the discharge of rainwater.
(FR)L'invention se rapporte à la fabrication d'éléments de construction en béton perméables à l'eau et mécaniquement résistants. Elle propose pour cela d'introduire dans une composition pour béton contenant du ciment et d'autres constituants tels des granulats 1, des éléments 4 substantiellement plats, notamment des produits coquilliers marins concassés qui en contrariant l'emboîtement serré des autres constituants tels les granulats 1 créent des porosités favorables à la perméabilité à l'eau. L'invention est applicable à la fabrication de pavés, dalles ou chapes coulées in situ notamment pour parking, voies de passage ou de circulation, auto drainantes qui permettent l'évacuation des eaux pluviales.
