Acoustic Emission behavior of thermally damaged Self-Compacting High Strength Fiber Reinforced Concrete
(Elsevier, 2018-10)
This paper investigates the effect of high temperature on two different Self-Compacting (SC) cementitious composites. SC-High Strength (SCHSC) and Fiber-Reinforced Concrete (SCHSFRC) samples were tested in three-point ...
Corrosion of Reinforced Concrete Exposed to Marine Environment
(Freund Publishing House Ltd, 2002-12)
The corrosion behaviour of reinforcing steel bars (rebars) was investigated in four different concrete mix designs commonly used in coastal cities in Argentina. Various exposure conditions were studied. Two water/cement ...
Verificação da tendência de penetração de cloretos em corpos de prova parcialmente imersos em água do mar Recife, PE
(Universidade Católica de Pernambuco, 2013-06-03)
Urban concrete or reinforced concrete structures built in saline environments, under
either intermittent or continuous sea water exposure, usually present mechanical wear
and structure pathology problems that require ...
Análise e dimensionamento do elemento pilar de um galpão de concreto pré-fabricado
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2018-06-18)
Prefabricated sheds are widely used, due to their flexibility in the architecture, the possibility of using large spans and open spaces. The present work aims to present the design of a pillar of a prefabricated concrete ...
Estudo da sinergia entre nano sílica e micro sílica em argamassas para aplicação em concretos como proposta de melhoria de desempenho
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-06-23)
Nowadays, in consequence of construction development, there is an increase in the size of the civil construction works, which the use of materials with better performances are required to meet the demand for quantity, ...
Resistividade elétrica de concretos com diferentes teores de escória de alto forno e ativador químico
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2005-12-15)
The integrity of the rebars in reinforced concrete structures is related to the chemical and physical protection provided by the concrete layer that covers the steel. The destruction of the passivation layer precedes the ...
Plasma cutting of concrete: Heat propagation and molten material removal from the kerf
(Institute of Electrical and Electronics Engineers, 2019-05)
An experimental investigation of heat propagation in the case of plasma cutting of concrete is reported. The experiments were carried out by using a high-enthalpy nitrogen plasma jet generated in a dc vortex-stabilized ...
Compressive strength of HPC contining CNI and fly after long-term exposure to a matine environment
(Cement & Concrete Composites, 2012)
This study addressed the effect of calcium nitrite based corrosion inhibitor (CNI) and fly ash (FA) on the long-term compressive strength of high performance concrete (HPC). A 33 full factorial design was developed to ...
Mechanical and durability properties of recycled aggregate concrete with ternary binder system and optimized mix proportion
