EVALUACIÓN DEL COMPORTAMIENTO EN COMPRESIÓN DE MORTEROS REFORZADOS CON ÓXIDO DE GRAFENO Y COSTOS INHERENTES AL PROCESO PRODUCTIVO DE LA MEZCLA

Abstract

In the present investigation, the potential of the graphite deposits in the Villonaco mountain in the province of Loja - Ecuador, is evaluated in order to obtain graphene oxide from the graffiti shales of the said deposit. Graphene oxide is used as a chemical additive to reinforce mortars, among other cement compounds. The graffiti shale samples obtained are subjected to mechanical and chemical processes to separate the carbon particles from other minerals. Subsequently, a calcination process was carried out to evaluate the percentage of carbon contained in the samples, obtaining an average of 6% of a 1g sample, which is insufficient to proceed with the chemical synthesis. It was decided to carry out the chemical synthesis process "Improved Synthesis of Graphene Oxide" in synthetic graphite since the reagents had been acquired. Once the synthetic graphene oxide was obtained in the laboratory, it was incorporated with equispaced increments of 0.03 to 0.06% of the weight of the cement contained in a mortar bucket (according to ASTM C 109). Comparatively, the compressive strength of mixtures of mortar reinforced with reduced graphene oxide. Obtaining an increase of the mechanical resistance to compression of the mortar cubes with incorporation of graphene oxide and reduced graphene oxide.
