Avaliação e caracterização do comportamento geomecânico de agregados oriundos de jazidas da região sudeste do Rio Grande do Sul e Santa Catarina
(Universidade Federal de Santa Maria, 2021-12-17)
The evaluation and characterization of mineral aggregate is extremely important in the paving scenario, considering that more than 80% of the volume of asphalt mixtures is composed of this type of material. Thus, its ...
Otimização de torres treliçadas de linhas de transmissão através do método teaching learning based optimization algorithm
(Universidade Federal de Santa Maria, 2022-02-09)
In the engineering field, the search for the best performance of a structure in terms of
economy, efficiency and safety is one of the main objectives. In this sense, in relation
to transmission line towers (TLT), it ...
Estudo do comportamento resiliente de um solo laterítico estabilizado com ácido fosfórico e cinza da casca de arroz
(Universidade Federal de Santa Maria, 2021-03-29)
In view of the need to expand the national road network, it is interesting to use local soils, in the structural layers of a pavement, thus reducing transportation costs. Sometimes, these soils do not have adequate support ...
Estudo da deformação permanente de concretos asfálticos aplicados em campo
(Universidade Federal de Santa Maria, 2020-10-15)
Transport on highways, mainly on asphalt pavement, is crucial for many countries around the globe, being
relevant to the economic and social contexts of a country. Another key factor is the mechanical behaviour of
asphalt ...
Estudo da ativação via carbonatação acelerada da escória granulada de alto forno (EGAF) para a produção de ligante especial
(Universidade Federal de Santa Maria, 2023-02-27)
The production of clinker, the main raw material for Portland cement, requires a
temperature of approximately 1450°C for calcining the raw materials, with high
consumption of limestone and clay and high CO2 emissions. ...
Medidas reológicas em pasta geopolimérica: efeito da geometria e protocolo de ensaio
(Universidade Federal de Santa Maria, 2023-01-26)
Understanding and optimizing the rheological properties of cementitious materials allows us to
determine and precisely adjust their workability. In addition, understanding its flow enables
predicting the behavior of the ...
Análise comparativa das barreiras de concreto de pontes e viadutos projetadas pelas normas NBR7188:1982 e NBR7188:2013
(Universidade Federal de Santa Maria, 2022-04-26)
In this work, a comparison is made between NBR7188:1982 and NBR7188:2013, referring to the behavior of the structural strength of the concrete barrier determined by its reinforcement, for bridge structures. For the development ...
Estudo de dosagens de misturas 100% RAP na fabricação de blocos para pavimentos intertravados
(Universidade Federal de Santa Maria, 2022-12-16)
In the process of restoring a highway, one of the biggest problems is the disposal of waste
generated by milling the asphalt coating. On the other hand, the cost of asphalt pavements
has risen more and more in recent ...
Avaliação da viabilidade da reciclagem de lodos de estação de tratamento de esgoto (LETE) e casca de arroz (CA) para a produção de blocos cerâmicos
(Universidade Federal de Santa Maria, 2023-01-17)
The population growth is directly related to the increased consumption of natural resources and the generation
of waste resulting from human actions, among which sewage stands out, which is a heterogeneous mixture
produced ...
Análise dos efeitos de segunda ordem globais de torção em edifícios altos em concreto
(Universidade Federal de Santa Maria, 2023-03-28)
Tall concrete buildings may have their structural behavior significantly influenced by
global second-order effects, resulting from geometric non-linearity, depending on certain
characteristics of the building. The ...
