Article of manufacture made of composite material, for incorporation into a civil engineering structure

摘要

An article (12) of manufacture is disclosed for incorporating into a civil engineering structure (3, 4), for example a concrete structure, such as a floor. The article comprises a substantially fully cured thermosetting polymer resin and a particulate aggregate material having a Mohs hardness of from 3 to 9, preferably from 5 to 8. The article optionally comprises a reinforcing fiber. The hardness of the article can be closely matched to that of the surrounding structure. The article can be ground with a diamond tool to form a smooth transition with the surrounding structure. The article is particularly suitable for incorporation into an exposed surface (7, 8) of the structure.
