Limitations of sorptivity and water permeability for the estimation of the chloride penetration rate in concrete regarding the accomplishment of prescriptive design for durability in the marine environment
(Asociación Latinoamericana de Control de Calidad, Patología y Recuperación de la Construcción, 2018-08)
This paper presents an analysis of experimental data from conventional concrete regarding sorptivity and penetrability under pressure comparing these paremeters to chloride diffusion rate determined in the laboratory and ...
Penetração de cloretos em concretos com diferentes tipos de cimento submetidos a tratamento superficial
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2010-08-31)
The durability characteristics of concrete should be given the same importance as compressive strength when designing concrete structures. Concrete should be able to
withstand the effects of aggressive agents and behave ...
CARACTERIZACION DE PROCESOS FISICOS EN MATERIALES BASADOS EN CEMENTO MEDIANTE INTERFEROMETRIA ULTRASONICA
(2011-06-02)
ABSTRACT
Chloride ions play an important role in the deterioration of concrete structures.
There are several test methods for evaluating the resistance of penetration of
chloride ions in concrete. Traditionally the ...
Failure analysis of reinforced concrete structures subjected to chloride penetration and reinforcements corrosion
(2016-01-01)
Structural durability is an important design criterion, which must be assessed for every type of structure, especially for reinforced concrete (RC) structures. When RC structures are located in aggressive environments, its ...
Penetração de cloretos em concretos compostos com diferentes teores de cinza de casca de arroz
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2004-12-21)
The service life of concrete structures can be extended by controlling aggressive agents often found in the environment that attack concrete. Such agents may cause structures to deteriorate and result in technical losses ...
Resistance of blended concrete containing an industrial petrochemical residue to chloride ion penetration and carbonation
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2014-03-19)
In this study, the resistance of blended concrete containing catalytic cracking residue (FCC) to chloride ion penetration and carbonation was examined. FCC was added at the levels of 10%, 20%, and 30% as partial replacement ...
Effect of silica fume addition on the chloride related transport properties of high performance concrete
(Universidad Nacional de Colombia Sede Medellín, 2012)
Corrosion of steel reinforcement due to chloride penetration is the major cause of durability problems in concrete. In that way, this paper summarizes the results of an experimental research carried out in order to investigate ...
Durabilidade de compósitos cimentícios de ultra alto desempenho com incorporação de pó de vidro frente à ação de cloretos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2021-03-25)
Reinforced concrete is one of the most widely used construction materials in civil construction, in Brazil and worldwide, due to the ease of taking on different shapes and for protecting the reinforcement from external ...
Penetração de cloretos em concretos compostos com cinza de lodo de estação de tratamento de água em diferentes teores de adição
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2017-08-31)
The increasing population growth has been responsible for the increasing demand for drinking water and, therefore, an increase in the amount of waste generated in Water Treatment Stations. In the vast majority of municipalities, ...
