Alkali–silica reaction in plain and fibre concretes in field conditions
(Springer, 2019-03)
This paper presents an experimental study on the effects of alkali–silica reaction (ASR) in concrete blocks placed outdoors, exposed to weather conditions. To promote different reaction kinetics and damage levels, the size ...
Expansive behavior of an alkali-carbonate reactive dolostone from Argentina: Proposal of an osmotic theory-based model to explain the expansion caused by the alkali attack
(Pergamon-Elsevier Science Ltd, 2020-12)
The expansion mechanism of dolomitic rocks in alkaline environments is complex and a current topic of debate, since two different chemical reactions can coexist: one linked with silica attack (alkali-silica reaction, ASR) ...
Contribution of fiber reinforcement in concrete affected by alkali-silica reaction
(Pergamon-Elsevier Science Ltd, 2015-01)
Fiber reinforced concrete (FRC) is a high performance material that is frequently used for structures in contact with aggressive environments, because the fibers can control the propagation of cracks. This paper analyzes ...
Parametric analysis of AAR influent factors on thin-walled columns
(Revista IBRACON de Estruturas e Materiais, 2015)
Mitigação da reação álcali-agregado em concreto com o emprego de resíduo de cerâmica vermelha e metacaulim
(Universidade do Vale do Rio dos Sinos, 2017-05-22)
The use of mineral additions through pozzolans, both naturally and artificially, has been adopted by several civil engineering professionals through the partial substitution of cement primarily in the production of concrete ...

Discussão sobre a caracterização da reatividade de agregados graúdo utilizados na fabricação de concretos.
(Universidade Católica de Pernambuco, 2021-02-19)
The alkali-aggregate reaction (AAR) is a deleterious chemical reaction that involves sodium and
potassium ions, mainly from Portland cement, some mineral phases that may be present in large
aggregates or small amounts ...
Análise de desempenho mecânico de elementos de concreto armado em face da reação álcali-agregadoThe mechanical analysis of reinforced concrete elements affected by the deleterious effect of the alkali-aggregate reaction
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2016)
Durable performance of recycled aggregate concrete in aggressive environments
(American Society of Civil Engineers, 2020-07)
Recycled aggregate concrete is an eco-friendly material that is increasingly being used in new constructions. Nowadays, this application is mainly limited by user?s lack of confidence, as coarse recycled aggregate (CRA) ...
