Electrical resistivity measurement of unsaturated concrete samples
(ICE Publishing, 2014-04)
Electrical conduction in concrete primarily occurs via the liquid in pores. Since concrete resistivity is sensitive to moisture content, resistivity can be used to infer other moisture-dependent concrete properties. However, ...
Compressive resistance of concrete produced with recycled concrete aggregate and sugarcane vinasse waste-water
(2022-02-01)
Vinasse is the main by-product of the sugar and alcohol industry. For each liter of ethanol produced from sugarcane, approximately 12–18 L of vinasse are generated. Being such, its use as a hydration agent in concretes may ...
EVALUATION OF THE INFLUENCE OF THE STANDARD FIRE RESISTANCE CALCULATION METHODS IN THE VERIFICATION OF CONCRETE WALL BUILDINGS
(Centro Federal Educacao Tecnologica Rio Grande Norte, 2021-01-01)
It is necessary, in order to carry out the assessment of concrete structures in a fire situation, to know the Standard Fire Resistance of the structural elements. Both the ABNT NBR 14432 (2001) and the ABNT NBR 15200 (2012) ...
Comparative study of concrete panels' fire resistance

Ductile Concrete End-Diaphragms of Slab-on-Girder Concrete Bridges
(2022-01)
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 ...
Differences on specified and actual concrete strength for buildings on seismic zones
(Earthquakes and Structures, 2018)
Application of UTHSCSA-Image ToolTM to estimate concrete texture
(2012-10-26)
The texture of concrete blocks is very important and is often the decisive factor when choosing a product, particularly if the building specifications does not dispense with the high resistance of the blocks, but has the ...
