Massive volume fly-ash concrete: A more sustainable material with fly ash replacing cement and aggregates
(2015)
Fly ash (FA) has been widely used to improve concrete sustainability for many years; however, the amount of FA has been limited by the relatively low cement contents in concrete. In this study, massive volume fly-ash ...

Influência de materiais de proteção superficial na resistividade elétrica e absorção capilar do concreto
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2011-01-24)
The durability of concrete structures is the result of protective action of concrete over the rebar. When the passivation of steel ceases to exist the structure
becomes vulnerable to the phenomenon of corrosion, which ...
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 ...
Absorção capilar e resistividade elétrica de concretos compostos com cinza de casca de arroz de diferentes teores de carbono grafítico
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2011-12-15)
There are constant searches for alternatives to reduce the environmental impact in
the production of in consumables, like concrete, that is actually a pollutant. Mineral
additions have been investigated as partial ...
Resistividade elétrica de concretos compostos com cinza de lodo de ETA e calcário moído
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2017-12-18)
Electrical resistivity, a property of the concrete that represents its resistivity to the
passing of electric current, is important in terms of corrosion of reinforced concrete
and, therefore, of the durability of the ...

(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2010-03-04)
This study investigated the effect of thermal treatment technique, used in two treatment conditions: treated wood in an autoclave and after conditioning, subject to the treatment under electric heater (combination), and ...
Determinação instantânea da relação água-cimento e da resistência à compressão do concreto no estado fresco através do método da resistividade elétrica
(Universidade do Vale do Rio dos Sinos, 2015-04-07)
During construction of concrete elements in the building site, quality control proceedings are adopted in order to verify if the concrete reaches its design specifications, which also avoids failures during the subsequent ...
