Abstract

The alkali-aggregate reaction is a pathological manifestation due from chemical processes of interaction of reactive minerals that are present in some aggregates, and alkali hydroxides from Portland cement, water kneading and external agents dissolved in the solution present in the pores of concrete. It is a reaction that occurs slowly, but may cause irreparable damage, for example with cracks that impair the mechanical strength and durability of the affected structure. The main objective of this work is to expand the existing knowledge about the evolution of this pathological manifestation in order to contribute to eradicate this problem in the construction works. The methodology used in the article includes a literature review that addresses a history of occurrence of alkali-aggregate reaction in Brazil and around the world, its definition, the types of reaction, the factors that influence it, control methods and some cases in Metropolitan region of Recife that had this pathological manifestation during the construction process and during its lifetime. The article here presented is intended to contribute to spreading a deeper understanding of this pathological manifestation as well, pointing out mitigating actions of its occurrence, it is a relevant tool for the technical means, the expected result with this production is to increase the knowledge of the theme proposed, as the increasing number of occurrence of this pathological manifestation in concrete structures.
