Abstract
The disclosure features structural tiles and methods for forming such tiles, the tiles including a tile body featuring one or more polystyrene materials, and a coating featuring an epoxy resin and an aggregate material, disposed on at least one surface of the tile body, where the structural tile has a dry coefficient of kinetic friction of at least 0.75 and a wet coefficient of kinetic friction of at least 0.70, and where the dry coefficient of kinetic friction is larger than the wet coefficient of kinetic friction by 0.05 or less.
Claims17
A structural tile, comprising:
- a tile body comprising a first functionalized polystyrene-based material, a second polystyrene-based material that is non-functionalized or functionalized differently than the first polystyrene-based material, and sand, and comprising a plurality of pores formed in the tile body;
- and
- a coating comprising an epoxy resin and an aggregate material, disposed on at least one surface of the tile body,
- wherein the structural tile has a dry coefficient of kinetic friction of at least 0.75 and a wet coefficient of kinetic friction of at least 0.70;
- and
- wherein the dry coefficient of kinetic friction is larger than the wet coefficient of kinetic friction by 0.05 or less.

A structural tile, comprising:
- a tile body comprising a first functionalized polystyrene-based material, a second polystyrene-based material that is non-functionalized or functionalized differently than the first polystyrene-based material, and one or more channels that extend from a top bearing surface to a bottom bearing surface of the tile body;
- a coating comprising an epoxy resin and an aggregate material, disposed on at least one surface of the tile body;
- and
- at least one conductive wire extending through the tile body and comprising electrodes attached to the at least one conductive wire, the electrodes positioned so that when two tiles are located adjacent to one another in a grid, the two tiles are electrically connected through the electrodes.
