Patent

CA 2403108

A concrete article is prepared by mixing concrete, water and a reinforcing polymer comprised of a substantially random interpolymer of at least one .alpha.-olefin, with at least one vinyl or vinylidene aromatic monomer and curing said concrete mixture to form a concrete article having the reinforcing polymer therein, such that the reinforcing polymer has a surface comprised of the substantially random interpolymer in contact with the concrete.

Selon cette invention, on prépare un article de béton en mélangeant d'abord du béton, de l'eau et un polymère de renfort constitué d'un interpolymère sensiblement aléatoire d'au moins une .alpha.-oléfine, avec au moins un monomère aromatique vinylique ou vinylidénique, et en faisant cuire ensuite ce mélange de béton pour obtenir un article de béton contenant le polymère de renfort, de sorte que la surface du polymère de renfort contenant l'interpolymère sensiblement aléatoire soit en contact avec le béton.
