“…In recent years, many researchers [5,10,11,19] studied the behavior of cement paste and cement mortar composites, when carbon fibers are added to concrete. Strain-sensing [17] and damage sensing properties [4,12,13,20,21] on cement composites has been studied by adding different percentages of carbon fibers and carbon nano tubes (CNT) and also in combination of both [22].…”

“…As the major work is done on cement and mortar paste, as compared to concrete, here is an attempt to work on concrete rather than cement or mortar specimens [16,19]. The main objective of this study is to extend the same strain and damage sensing property of cement composites to the conventional concrete for the purpose of health monitoring of concrete structures.…”

A B S T R A C TPresent paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were tested under cyclic loading within elastic region of the sample for three cycles of loading with a maximum load of 195kN for strain sensing test. During cyclic loading, fractional change in resistance (FCR) is calculated and co-relation with the stress is plotted. During strain sensing test, gauge factors (GF) were also calculated during loading and unloading on the samples. From obtained results, it is found that the concrete sample containing 1.5% of carbon fibers by weight of cement gives best co-relation between stress and FCR that can be further used for health monitoring purpose. Along with strain sensing property, damage sensing property and ultimate load carrying capacities of all the specimens are also reported in present paper with detailed explanation.

La comparación del rendimiento de los compuestos de FAP-CRF con nanofibras de carbono o nanotubos, NFC o NTC, respectivamente, se realizó con una mezcla de referencia (Ref Para realizar el concepto propuesto de CRF autodetectable, es importante la distribución uniforme de fibras / tubos de carbono dentro de la matriz de cemento [10].

“…La dispersión de las NFCs / NTCs se hizo antes de sumarlos en el CRF autodetectable. En un trabajo previo [10] se pueden encontrar detalles del procedimiento de dispersión de las NFC en agua utilizando un superplastificante basado en PCE y tratamiento con ultrasonidos. La dispersión apropiada de NTC en agua se consiguió mediante el mismo procedimiento utilizado para las NFC, adicionando la cantidad de 5% de arena de sílice de la mezcla total del compuesto.…”

RESUMENLa adición de fibras en morteros compuestos a base de cemento portland es una práctica común para la prevención de la formación de grietas y para incrementar la resistencia a la flexión. En esta investigación, se estudiarán morteros Compuestos Fibro-Reforzados (CFR) con Fibras de Alcohol Polivinílico (FAP), reforzadas con Nanofibras de Carbono (NFC) o Nanotubos de Carbono (NTC) para el desarrollo de sistemas de Supervisión de la Salud Estructural (SSE). Los especímenes fabricados fueron ensayados a la resistencia a la flexión, absorción de agua y a la conductividad eléctrica en agua o en solución con NaCl. Los resultados demostraron una dependencia de los especímenes al tipo de solución a la cual fueron expuestos. Se demostró que la sensitividad a la deformación y a la solución de NaCl puede ser incrementada por la adición de los NTC. Los resultados en el incremento de la conductividad con los compuestos de NTC pueden ser escalables para las aplicaciones de monitoreo no-destructivo en estructuras de autodetección de concreto que requieran una mejora integral bajo las cargas aplicadas y estabilidad en ambientes deletéreos.PALABRAS CLAVE: nanofibras, nanotubos, compuestos, conductividad eléctrica, resistencia a la flexión.
