Dimensionamento de elementos estruturais em concreto leve
(Universidade Federal de São Carlos, 2015-04-22)
The lightweight concrete for structural purposes is a material that has great potential for
application in various construction areas. Its main feature is the reduced density
compared to conventional concrete. This ...
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 ...
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 ...
Matriz cimentícia produzida com resíduo agroindustrial: reação álcali-agregado, ataque por sulfatos e passivação do aço
(Universidade Federal de São Carlos, 2019-02-27)
The proposal of this research includes the incorporation of residues in concretes and the study of the durability in these concretes with respect to the alkali-aggregate reaction (AAR), to the sulfate attack (SA) and to ...
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, ...
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 ...
Programa computacional para análise e verificação de seções de concreto armado e protendido com flexão oblíqua composta
(Universidade Federal de São Carlos, 2015-03-31)
In this paper, a free analysis program is presented for the verification of ultimate and serviceability limit states of reinforced or prestressed concrete sections with polygonal shape submitted to axial forces and biaxial ...
Estudo de viabilidade técnica da utilização da ACBC e do RCC na composição de concretos
(Universidade Federal de São Carlos, 2014-02-25)
The civil construction is responsible for generating a lot of waste and the lack suitable for waste treatment can cause many environmental and social problems. Brazil is the world s largest producer in the sugar and alcohol ...
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 ...
