Abstract

There is disclosed a method for multi-axial confinement of materials such as cementitious composites and particulate structures, using a polymer as a composite, which can return to an original shape upon heating. The mechanical action of the polymer will cause strain, for example compression, in the material to be confined. Examples of uses include strengthening of concrete structures, repair, autogenic healing of cracks in concrete, wrapping damaged structural elements and reinforcement of particulate structures such as flood defences and railway embankments.
