    Obtención de materiales vitrocerámicos a partir de desechos industriales para el revestimiento de tuberías

    In this work it was proposed to address the problem of industrial waste management by obtaining glass-ceramic materials for the internal coating of pipes, using the epoxy powdering technique since at the moment there is excessive heat transfer in the pipes. Initially, exhaustive research was carried out on the wastes that are suitable for obtaining glass-ceramic materials, these being glass, steel slag and electro plastic sludge. Information was found on the processes of obtaining materials by combining pure and natural raw materials, focusing on the application of glass-ceramic materials obtained from industrial wastes in mechanical engineering; in the development of the project, tests were carried out to characterize the material, using X-Ray spectrometry to analyze the composition of the mixture, hardness and flexural tests were carried out to evaluate the mechanical properties of the glass-ceramic material; these tests provided crucial information on the strength and deformation capacity of the material, essential aspects for its application in mechanical engineering. It is emphasized that the results obtained revealed the feasibility of using industrial wastes to produce glass-ceramic materials with favorable mechanical and chemical properties. Hardness and flexural tests supported the applicability of these materials in mechanical engineering, offering a significant contribution to the field of advanced materials. The study opens new perspectives for the implementation of these sustainable and efficient materials in various industries, highlighting their potential in pipe coating for various applications. Keywords: Industrial Waste, Materials, Coating, Piping, Glass ceramics.

    Análisis de la resistencia a compresión del hormigón al reemplazar parcialmente el agregado fino por escoria siderúrgica de horno eléctrico
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Civil, 2018) Laica Fernández, Darío Javier; Ureña Aguirre, Maritza Elizabeth
    The objective of the experimental work was to analyze the results obtained through tests of the ZHIMADZU compression machine, model CONCRETO 2000X for specimens of 100mm diameter by 200mm height with partial substitutions of 0%, 10%, 20% and 30% of fine aggregate by steel slag for ages of 14, 28 and 60 days of age in addition to undergoing death and death by 60 days of age, to determine how it influences the resistance to compression. In order to carry out the concrete tests, the analysis of the aggregates in the elaboration of the concrete for the design of the mixture with a density of 240 kg / cm2 was used, reaching to determine the granulometry, the loose bulk density, the compacted bulk density, Relative density and absorption capacity as described in Standards NTE INEN 696, 858, 856, 857 and 156. Once the appropriate dosage was made, 96 specimens were prepared for their designs. The specimens were processed to perform the compression tests at 14, 28 and 60 days of age, obtaining information on how to influence the steel slag in the compressive strength in cement in its different percentages of magnesium sulfate replacement. MgSO4, under the criterion of ACI318-14, where it was possible to notice the disintegration of the cement paste, the increase in its dimensions, the appearance of microcracks and a great loss of resistance after having been subjected to cycles of immersion, drying and cooling in magnesium sulfate.
