Patent

CA 2583082

A concrete formulation, which undergoes controlled deterioration in water, that can be used for making anchors for releasably tethering submarine devices at the seabed. The anchor may have handles for a device release mechanism or a central hole for a central device release mechanism. The formulation includes additives, which cause the cement to transform into non-binding Thaumasite over a pre-set period of time, leaving only natural material on the seafloor.

L'invention concerne une préparation de béton exposée à une dégradation régulée dans l'eau pouvant être utilisée pour fabriquer des ancres permettant d'amarrer de façon amovible des appareils sous-marins sur un fond marin. L'ancre peut posséder des poignées servant à un mécanisme de libération de dispositif ou un trou central servant à un autre mécanisme de libération de dispositif central. La préparation comprend des additifs amenant le ciment à se transformer en un thaumasite non liant sur une durée prédéterminée, ne laissant que de la matière naturelle sur le fond marin.
