Manufactured article made of composite material to be incorporated into a civil engineering structure

摘要

A system expansion joint (12) to be incorporated in a concrete structure, the system expansion joint a first expansion joint (13) and a second expansion joint (14) comprising, the first element expansion joint (13) a nonlinear first surface (18), the second element of expansion joint (14) a second non-linear surface designed to mate with the first non-linear surface (18), wherein the system expansion joint prior to incorporation in the concrete structure comprising a resin substantially thermoset polymer and fully cured, and added a particulate material having a Mohs hardness in the range of 3 to 9, preferably within the range 5 to 8 and that the first element of the expansion joint (13) and the second element of the expansion joint (14) have a hardness within 20%, preferably dentr or 10%, of a hardness of the concrete structure, comprising the expansion joint system (12) from 40% to 90% by weight of the aggregate particle material.
