Effect of sedimentary and metamorphic aggregate on static modulus of elasticity of high-strength concrete
(Universidad Nacional de Colombia Sede Medellín, 2011)
Taking into account the increasing use of high-strength concrete as a structural material in Colombia, this paper shows the results of research carried out to investigate the effect of different types of coarse aggregate ...
Análise da influência da resistência à compressão de diferentes concretos na aderência com a armadura
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia CivilUTFPR, 2016-06-24)
In recent decades, concrete has become the most commonly used material in construction. The reinforced concrete, study object of this work, is a concrete structure which has a reinforcement with steel bars inside. Its ...
Effect of steel fibers on static and blast response of high strength concrete
(Pergamon-Elsevier Science Ltd, 2017-09)
The advantages of High Strength Fiber Reinforced Concrete (HSFRC) in static behavior highlighted by many researchers suggest it is a promising material to withstand dynamic loads. However, available experimental results ...
Estudo da variação na resistência a compressão de concretos convencionais devido aos diferentes tipos de cura
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2013-07-15)
Why the curing of concrete is often neglected? Our desire for rapid production is usually the 1st culprit. People often have no patience, especially when time is money, and healing requires patience and attention to detail. ...
Análise dos mecanismos de transferência de esforços de cisalhamento em peças de concreto armado convencional e reforçadas com fibras de aço e PVA
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia CivilUTFPR, 2019-11-13)
Despite being the most used material in construction, there are still difficulties in estimating the shear strength of reinforced concrete, especially when fibers are used. The present study analyze the ultimate shear ...
Avaliação do ensaio Barcelona como controle tecnológico do concreto reforçado com fibras de aço
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia CivilUTFPR, 2018-11-06)
Concrete structures require reliable, economic and, preferably, simple execution methods. In case of fiber-reinforced concretes (FRC), this control is based on tenacity and residual resistances, usually obtained from beam ...
Avaliação das propriedades do concreto de pós-reativos: um estudo de durabilidade
(Universidade Tecnológica Federal do ParanáCuritiba, 2014-05-05)
With the advancement of technology and the need to build structures increasingly resistant and slim, new types of concrete have been developed to meet this demand. After conventional concrete, it has been the development ...
Application of UTHSCSA-Image ToolTM to estimate concrete texture
(2012-10-26)
The texture of concrete blocks is very important and is often the decisive factor when choosing a product, particularly if the building specifications does not dispense with the high resistance of the blocks, but has the ...
