    Análisis comparativo de la resistencia a la compresión del hormigón con adición de virutas metálicas y un hormigón con materiales tradicionales
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-02) Acosta Villacres, Edwin Manuel; Peñafiel Valla, Lourdes Gabriela
    The purpose of this experimental work is to offer an alternative to commercial products in which it seeks to verify if metal chips can be used in a mixture to enhance the physical and mechanical characteristics of concrete, in order to take advantage of those generated in some workshops. of turning in Ambato. Two dosages of compressive strength = 240 and 280 kg/cm2 were carried out, where percentage of metal chips were added in 5, 10 and 15 percent, specific tests of fine aggregate, coarse aggregate and cement were carried out, in addition The determination of the real density of these for the selection of the chip was based on investigative background which were spring-shaped chips of 5 cm in length, the analysis of the mechanical resistance of the concrete was carried out at 7, 14 and 28 days based on the NTE INEN 1573 standard The results were compared between the concrete of the standard specimens and the specimens with metal shavings in the percentages already mentioned, they showed an improvement in the dosage of 280 kg/cm2 that incorporated 5 percent, increasing its resistance by 113.46 percent, for the dosage of 240 kg/cm2 there was no increase, but the resistance was maintained within the permitted ranges, however for the percentages of 10 and 15 percent of metal chips in both dosages its resistance decreased, obtaining a very weak concrete.
