O uso de resíduo de construção civil como substituto de agregados naturais em concretos: avaliação de alguns parâmetros de durabilidade
(Universidade Federal de São Carlos, 2018-05-03)
The concern about the environmental impacts generated by the construction industry, which traditionally requires large quantities of raw materials and usually generate a large amount of waste, motivated the development of ...
Verificação à fadiga de vigas de pontes de concreto armado: estudo comparativo entre o uso do trem-tipo normativo e as cargas reais nas rodovias brasileiras
(Universidade Federal de São Carlos, 2019-12-11)
Bridges and viaducts are important in the social and economic dynamics of a nation, and they are very important elements in transportation systems. In Brazil, freight transportation is predominantly by road. Therefore, ...
Estudo sobre a substituição de armadura metálica por barras de GFRP em vigas de concreto armadas à flexão quando submetidas ao ataque acelerado de íons cloreto
(Universidade Federal de São Carlos, 2020-02-28)
The use of reinforced concrete structures with steel bars is recurrent in the construction industry in Brazil. However, alternative materials are studied due to the existence of problems related to the use of this traditional ...
Durabilidade de vigas de concreto armado reforçadas com mantas de CFRP submetidas a degradação acelerada
(Universidade Federal de São Carlos, 2020-02-27)
Currently, as an alternative to reinforced concrete structures, which have suffered physical or chemical degradation, strengthening systems have been used which use composite materials. Composites are formed by combining ...
Estudo da carbonatação de concretos com adição de nanosílica
(Universidade Federal de São Carlos, 2019-04-29)
The degradation of reinforcing concrete structures reflects in economic and environmental factors. Thus, the desire to minimize it motivates recent research, which aims to add nanomaterials to the cement matrix, seeking ...
Aplicação do concreto de ultra alto desempenho em viga pré-moldada protendida para pontes
(Universidade Federal de São Carlos, 2021-08-25)
Several requirements and challenges of modern construction motivated the development of High-Performance Concrete (HPC) and later, with the advance of the research, the Ultra-High Performance Concrete (UHPC). Due to the ...
Estudo sobre o impacto da redução do consumo de cimento no comportamento mecânico do concreto autoadensável
(Universidade Federal de São Carlos, 2016-04-01)
This paper presents an analysis of the development of self-compacting concrete with low consumption of Portland cement, and evaluates some of its properties in fresh and hardened state ( mechanical properties ). The ...
Estruturas de concreto armado em ambiente urbano: avaliação de carbonatação à luz das recomendações da NBR 6118:2003.
(Universidade Federal de São Carlos, 2006-02-22)
This present paper evaluates the depth of carbonation of concrete test samplers taken from existing buildings where it was possible to recover the registers of concreting such
as: date of execution, concrete mixture ...
Estudo da eco-eficiência de argamassas e concretos reciclados com resíduos de estações de tratamento de água e de construções e demolições.
(Universidade Federal de São Carlos, 2006-02-23)
Traditional and recycled mortar and concrete have been produced and the results from simple
compression strength and water absorption tests have been compared. Recycled mortar and
concrete have been produced out of sludge ...
Captura de CO2 em peças de concreto para pavimentação através da cura por carbonatação acelerada
(Universidade Federal de São Carlos, 2019-02-28)
The construction sector stands out as responsible for the emission by third of the total greenhouse gases emitted by mankind. The processes of extraction and manufacture of the raw materials, necessary to obtain the concrete, ...
