description La disposición de la cáscara de coco es un problema de eliminación de desechos en países como indonesia, filipinas y la india, donde se concentra la mayor producción de coco en el mundo. Cuando la cáscara de coco se calcina produce cenizas, las cuales son un material aglutinante potencial para preparar hormigón. En este trabajo se calcinó cáscara de coco a tres temperaturas diferentes a saber: 400 °C, 500 °C y 600 °C durante un periodo de 3 horas. Las cenizas producidas se emplearon como sustituto del cemento. Las características físicas y químicas de las cenizas se evaluaron por área superficial y DRX. El efecto de la sustitución parcial de las cenizas en reemplazo del cemento se evaluó mediante ensayos de trabajabilidad y resistencia mecánica como la densidad, el asentamiento, resistencia a compresión. Los resultados experimentales demostraron que 600 °C es la temperatura de combustión más adecuada para la calcinación de la cáscara de coco, con presencia de SiO2 amorfo y una menor área superficial al aumentar la temperatura de calcinación. Además, en contraste con el hormigón de control, el aumento de la temperatura de combustión disminuye la trabajabilidad medida en asentamiento del concreto. pero mejora su resistencia mecánica. Finalmente, la resistencia a compresión de la mezcla que incorporó cenizas de cáscara de coco calcinadas a 600 °C fue superior a las demás. Se encontró adicionalmente que esta temperatura era convincente considerando el costo de preparar las cenizas.

When coconut shell is calcined it produces ash, which is a potential binding material for preparing concrete. In this work, coconut shell was calcined at three different temperatures, namely: 400 °C, 500 °C and 600 °C for a period of 3 hours. The ashes produced were used as a substitute for cement. The physical and chemical characteristics of the ashes were evaluated by surface area and DRX. The effect of the partial replacement of the ashes in replacement of the cement was evaluated by tests of workability and mechanical resistance such as density, settlement, compressive strength. The experimental results showed that 600 °C is the most suitable combustion temperature for the calcination of the coconut shell, with the presence of amorphous SiO2 and a lower surface area when the calcination temperature increases. Also, in contrast to the control concrete, increasing the combustion temperature decreases the slump-measured workability of the concrete. but improves its mechanical resistance. Finally, the compressive strength of the mixture that incorporated coconut shell ashes calcined at 600 °C was higher than the others. This temperature was further found to be convincing considering the cost of preparing the ashes.ceiler.cossiosan@campusucc.edu.coeliana.williams@campusucc.edu.codissy.palacios@campusucc.edu.co11 p.Universidad Cooperativa de Colombia, Facultad de Ingenierías, Ingeniería Civil, Medellín y EnvigadoIngeniería CivilMedellínCáscara de cocoAnálisis de costosPropiedades mecánicasTratamiento térmicoResiduos agroindustrialesHormigónTG 2023 ICI 49327Coconut shellCost analysisMechanical propertiesHeat-treatmentConcreteAgro-wasteCeniza de cáscara de coco como sustituto del cemento: efecto de la temperatura de calcinación.Trabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1finfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionAtribución – No comercial – Sin Derivarinfo:eu-repo/semantics/closedAccesshttp://purl.org/coar/access_right/c_14cbY.
