Durabilidade do concreto com cinza de casca de arroz natural sem moagem: mitigação da reação álcali-sílica e penetração de cloretos
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2011-05-06)
Natural rice husk ash (RHA) used in concrete contributes to civil construction sustainability. In fact, RHA is considered a residual pollutant and then it is necessary to destine this material correctly. However, it is ...
Concrete cracking control in underwater marine structures using basalt fiber
(IOP Publishing Ltd, 2021-02-05)
The construction of coastal ports requires the use of materials that meet the demands of the marine environment, to prevent underwater concrete structures from cracking and spalling easily; basalt fiber is used to delay ...
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 ...
Reação alcali-agregado, principais causas e estudo de reatividade potencial
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2015)
The relevance of executing the technological controlling of construction materials is increasing in importance in many civil engineering areas, including edifications free of construction pathologies and with good durability. ...
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) ...
Análise comparativa do módulo de elasticidade calculado segundo diferentes normas
(Universidade Católica de Pernambuco, 2014-06-09)
The work involved studying the behavior and adjustment of dosage diagram of concrete with respect to static and dynamic elastic modulus. Furthermore, it compares the models of the static elastic modulus based on the ...
