Determinación de la profundidad de carbonatación y su influencia en la pérdida de resistencia del hormigón armado en las pilas del paso a desnivel ubicado en la parroquia Tarqui de la ciudad de Manta.

Abstract

The objective of the present study is to determine the depth of carbonation and its influence on the loss of compressive strength of concrete in the Piles of the Tarqui Overpass, in order to determine a correlation equation that allows calculating the depth of carbonation with respect to a given compressive strength. The carbonation depths are presented in millimeters and the correlation is linear, carried out with 8 samples which were extracted through the Diamantina Test and tests in the Soil Laboratory of the Laica Eloy Alfaro University of Manabí. The carbonation depths of 4 piles of the Tarqui Overpass were obtained as a result, and an equation was obtained that allows the carbonation depth to be correlated with the compressive strength P = 62.7377+(-0.2584 R), which allows us to analyze that The piles that have a greater depth of carbonation, in this case Pile 3, are more susceptible to the loss of compressive strength, because the carbonation attacks a structural area. located. Studies show that as the depth of carbonization increases, the vulnerability of concrete to the external environment increases, which directly affects its mechanical strength and durability.
