Sustainable urban pavement for cities affected by El Niño using porous concrete
(IOP Publishing Ltd., 2021-02-05)
The El Niño phenomenon is caused by the change in atmospheric pressures, which produce the accumulation of hot surface waters on the eastern flank of the Pacific Ocean; causing intense rainfall that runs over the surface ...
Transporte de calor, umidade e sal em meios porosos
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia QuímicaEngenharia QuímicaUTFPR, 2019-07-01)
Concrete structures can suffer from different types of damage, which can considerably shorten their life. One of the responsible for this process is the transport of salts into the pores of the concrete. Besides accelerating ...
Constitutive formulation, localization and failure analysis of porous materials like concrete subjected to high temperatura
(International Amusement Manufacturing Company, 2014)
In this work, a thermodynamically consistent non-local poroplastic constitutive theoryfor quasi-brittle materials like concrete subjected to high temperature is presented [1].
Thereby, gradient poroplasticity and fracture ...
Approximation by the Finite Element Method to the Preferential Chloride Diffusion through Interfacial Transition Zone in Concrete
(Planta Piloto de Ingeniería Química, 2011-07)
Chloride diffusion in concrete is a main aspect of reinforced concrete durability. It defines the time required for reinforcement corrosion in marine structures. Concrete porosity is one of the main concerns involved in ...
Análisis de la Flexo Tracción del Concreto Permeable
(Instituto Tecnológico de Costa Rica, 2009)
The principal goal in this project is to determine the ruptura modulus or the strength to the slip tensile of the porous concrete and by the way correlate this datas with the strength to the compression that this knd of ...
