Abstract:
1. A construction structure comprising: (a) a substrate made of a concrete material and providing an external surface; and (b) an external mechanical metallic reinforcement attachment having an outwardly facing surface, and a roughened or sandblasted inwardly facing surface for improving adhesive bonding with said substrate, and said reinforcement attachment having a non-uniform cross-sectional area along a length of said reinforcement attachment; wherein said reinforcement attachment is secured directly to said concrete substrate with the inwardly facing surface bonded to the external surface of said substrate, said reinforcement attachment having at least one first portion and one second portion, said attachment is treated such that the first portion has a greater cross-sectional area than the second portion for increasing yield strength of the first portion whereby when said construction structure is under loading the first portion blocks or reduces spreading of strain sustained by said reinforcement attachment and thus minimizes debonding of said reinforcement attachment from said concrete substrate; and wherein said reinforcement attachment is adhesively bonded to said substrate.
