En este trabajo se evaluó la resistencia a la corrosión debida a la carbonatación en concretos fabricados con cementos LC3 encontrando que esta fue directamente proporcional al factor clínker del cemento, particularmente en condición acelerada. Los cementos LC3 fueron formulados ajustando su contenido de SO3 mediante la evaluación del proceso de hidratación en la pasta de cemento. Las pruebas de carbonatación fueron ejecutadas mediante métodos acelerados en la pasta, mortero y concreto, y también se desarrollaron pruebas en condición natural. También, se estudió el efecto de la carbonatación sobre la resistencia a la compresión del mortero, encontrando un buen desempeño para cementos con mayores factores clínker. El estado del acero de refuerzo en concretos expuestos a carbonatación natural y acelerada fue evaluado mediante las técnicas electroquímicas de resistencia a la polarización lineal (LPR) y espectroscopia de impedancia electroquímica (EIS), evidenciando que los efectos de la carbonatación acelerada en la reducción de la resistencia eléctrica de los concretos LC3 y la presencia de corrosión del acero inician antes de que el frente de carbonatación alcance la superficie de la barra de acero. Adicionalmente, la evaluación de la corrosión mostró que los concretos con cementos adicionados en grandes proporciones son más vulnerables a la corrosión debida a la carbonatación, existiendo un mayor riesgo en aquellos con menores factores clínker. (Texto tomado de la fuente)Portland cement blended with limestone and calcined clay (LC3) is a material capable of developing mechanical properties comparable to ordinary Portland cement (OPC), allowing a dense microstructure rich in aluminates to be obtained that improves the resistance of concrete to attack by chlorides and the alkali silica reaction, and brings environmental, technical and economic benefits to society. In this work, the resistance to corrosion due to carbonation in concrete made with LC3 cements was evaluated finding that it was directly proportional to the clinker factor of the cement, particularly in the accelerated condition. LC3 cements were formulated by adjusting their SO3 content by evaluating the hydration process in the cement paste. Carbonation tests were carried out using accelerated methods on paste, mortar and concrete, although tests were also carried out in natural conditions. Also, the effect of carbonation on the compressive strength of the mortar was studied, finding a good performance for cements with higher clinker factors. The state of reinforcing steel in concrete exposed to natural and accelerated carbonation was evaluated by electrochemical techniques of linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS), showing that the effects of accelerated carbonation on the reduction of the electrical resistance of the LC3 concrete and the presence of steel corrosion begin before the carbonation front reaches the surface of the steel bar. Additionally, the corrosion evaluation showed that concretes with cements blended in large proportions are more vulnerable to corrosion due to carbonation, with a higher risk in those with lower clinker factors.MaestríaMagister en Ingeniería - EstructurasMateriales para construcciónxxxi, 265 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - EstructurasFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá690 - Construcción de edificios::693 - Construcción en tipos específicos de materiales y propósitos específicosHormigónCompuestos cementososConcreteCement compositesCemento con caliza y arcilla calcinada (LC3)CarbonataciónCorrosiónLimestone calcined clay cement (LC3CarbonationCorrosionEvaluación de la resistencia a la corrosión debida a carbonatación en concretos con cementos pórtland adicionados con caliza y arcilla calcinadaEvaluation of corrosion resistance due to carbonation in concrete with portland cements blended with limestone and calcined clayTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionDataPaperTexthttp://purl.org/redcol/resource_type/TMY.
