Self-compacting concrete has specific characteristics that differ from conventional concrete. Its self- compacting capability, ease of pumping, excellent homogeneity and resistance to segregation are highlighted, being ...

The use of prestressed hollow core slabs has increased significantly and, consequently various productive methods have emerged. These methods do not employ machinery such as extruders or slip former machine. In this research, ...

The structural behavior of the prestressed steel concrete composite beams was investigated using the Finite Element Method. The present study reports two types of composite beams: steel beams and concrete slab with joint ...

The construction industry is the main generator of waste in the economy. The CW can account for up to 70% of total urban solid waste produced (SINDUSCON, 2015), resulting in a concern for the waste of materials extracted ...

Self-compacting concrete (SCC) must simultaneously exhibit high fluidity, cohesion and absence of segregation. However, the maintenance of these properties in the fresh state requires a greater consumption of binders and ...

In this dissetation exploratory models are used to examine the behavior of semi - rigid pillar - beam connections with shear key. This type of connection is ordinary in Brazil prefabricated concrete structures. Thus, the ...

This work aims to document the production process and characteristics of the new Brazilian prestressing steel CP-210 RB, as well as evaluating its use viability and to indicate design guidelines for the application in the ...

In service, excessive deformations can lead a geossynthetic soil reinforced structure to failure or undermine it under operational condition. In the design, usually, because of the uncertainly of the long-term efforts, ...

The potential shortage of natural resources, the increased demand for energy and the environmental impacts caused by the use of polluting energy sources have generated constant discussions and uncertainties about the world's ...

There is no consensus in the estimation of the number of native species coming from the Amazon Forest, and it is necessary to study the technological properties of tropical wood species for the rational use of this ...
