Permeabilidad y estructura porosa de hormigones autocompactantes de resistencia moderada

Abstract: RESUMENEl hormigón autocompactante ha experimentado un amplio desarrollo en los últimos años. Los estudios sobre este hormigón se han centrado en obtener dosificaciones óptimas, mientras los relativos a su durabilidad son escasos, especialmente en el caso de hormigones de resistencia moderada.Este trabajo se centra en el estudio de la permeabilidad de distintos hormigones autocompactantes de resistencia moderada (resistencia característica 30 MPa). El estudio incluye hormigones fabricados con cementos comunes,… Show more

“…The values of porosity were low due to the large amount of fine particles, which accords with previous studies [14,27,32]. However, the samples covered with a plastic film during setting showed lower average pore diameter, larger MIP porosity and tortuosity than the samples subjected to an airflow.…”

“…A general tendency relating to these both parameters was deduced, as lower pore size led to larger tortuosity. It has been already reported that water permeability depends on the pore size for moderate strength SCC [32]. Therefore, it can be concluded that better curing conditions would decrease water permeability due to the effect of small pores size in increasing the tortuosity of the porous network.…”

“…Figure 6 allows us to conclude that the viability of the various mixtures was kept within the consistency range (9.6 to 12.8 cm). These values were in accordance with other researches (Bermejo et al 2010;Carro-López et al 2018;Mefteh et al 2013).…”

“…For instance, stagnant water due to rains may affect ancient and modern buildings and monuments such as fountains, terraces and basements (1,2). Other examples can be found in subsurface quarries of building stones (3) or ancient hydraulic constructions, such as bridges, aqueducts, dams or canals (4)(5)(6).…”
