The search for the knowledge of civil constructions execution, lead us to find new technologies. With the reduce of the time of execution, new construction methods are needed and to be improved every day. One important ...

Previously it was believed that all structural materials used in construction had everlasting durability. Today, though this view is no longer a reality. The Portland cement concrete, being the most widely used construction ...

The action of the weather is inevitably linked to construction. All works, completed or in progress suffer from heat, cold, rain and wind. Low temperatures are common and unavoidable in several cities in Brazil and the ...

Rebar corrosion is a common pathology in reinforced concrete. One of the more worrisome ways this pathology presents itself is with the penetration of chloride ions in the concrete cover layer, due to the rapid loss of the ...

The relevance of executing the technological controlling of construction materials is increasing in importance in many civil engineering areas, including edifications free of construction pathologies and with good durability. ...

Concrete is the most used material in construction and better suited to resist compressive loads. Since it an indispensable material and that in its aging is subject suffering from various types of conditions and with high ...

In this paper, the results of the proposed ductile precast concrete end-diaphragm beams for the transverse seismic resistance and protection of the substructure of slab-on-girder concrete bridges, tested at the facilities ...

Grain storage silos, as well as any other civil construction, are susceptible to pathologies and can thus compromise their life cycle and reduce their performance. The study of pathologies may contribute to avoid future ...

Recycled concrete presents a higher porosity than traditional concrete, making it more susceptible to external agents and favoring the development of different pathologies in reinforced concrete structures. In particular, ...
