Abstract:
1. A method of building a reinforced construction structure, comprising the steps of: (a) providing a substrate made of a concrete material; (b) preparing a reinforcement attachment made of a metallic material having a first or inwardly facing surface for engagement with the substrate and a second or outwardly facing surface on opposite side thereof; (c) identifying and dividing the attachment into at least a first portion and a second portion, each of the first portion and the second portion has two surfaces; (d) treating the attachment with surface nanocrystallization by surface mechanical attrition treatment such that one or both of the surfaces of the first portion is or are nanocrystallized and the surfaces of the second portion is or are either not nanocrystallized or the surfaces of the first portion possess a greater degree of surface nanocrystallization than the surfaces of the second portion whereby the surfaces of the reinforcement attachment are zoned with different degree or extent of nanocrystallization; and (e) securing the attachment to the substrate whereby when the construction structure is under stress the first portion blocks or reduces spreading of strain across the attachment.
