Application of UTHSCSA-Image ToolTM to estimate concrete texture
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 ...
Corrosion in concrete structures with permanent deformation in marine environment
(Bentham Science Publishers, 2017-01)
Concrete is usually highly alkaline (pH around 12), thus protecting reinforcement against corrosion. The occurrence of oxides is favored when the medium pH surrounding the bar is in values near to 9 or lower. Aggressive ...
Brazilian results on structural masonry concrete blocks
The purpose of this paper is to study the mechanical behavior of concrete blocks and prisms when performing axial compression tests within the Brazilian base of knowledge, intending to foment data of this kind for a ...

ANÁLISE DAS PROPRIEDADES MECÂNICAS DE CONCRETOS PARA PAVIMENTAÇÃO EMPREGANDO DIFERENTES PROCESSOS DE CURA
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2014-08-25)
To develop a project sizing concrete pavement is necessary to know the mechanical properties and the different treatment processes of material to be used. This study aimed to analyze the mechanical properties such as ...
Resistência à compressão do concreto autoadensável: Influência da atividade pozolânica do calcário e do basalto
This research studies the influence of the pozzolanic activity of the calcareous and basalt in the resistence behavior of the compressive strength of high performance self-compacting concrete (HPSCC). The selected aditives ...
Physical–mechanical behavior of concretes exposed to high temperatures and different cooling systems
(Wiley Blackwell Publishing, Inc, 2017-06)
Over their lifetime, concrete structures can suffer from different pathologies, one of them is exposure to high temperatures, which diminishes their load-bearing capacity. This study describes how different concrete types ...
