Determinación del comportamiento mecánico mediante el ensayo de resistencia a la compresión de concreto adicionado con cementante reutilizado proveniente de escombros de la construcción usando un análisis estadístico inferencial.

Abstract

This research project seeks to evaluate a possible alternative for the use of construction debris, in addition to the existing ones; to know the effect that a replacement of Portland cement of general use by cementitious material coming from construction rubble would have from the compression resistance test, additionally determine the effect of its use by means of an inferential statistical analysis. From the selection, crushing, mix design, manufacture and failure of specimens, additional statistical analysis, it was established that the modulus of fineness obtained was similar to that of Portland cement. This characteristic allowed acquiring a greater surface area, managing to contribute to the hydration of the concrete and reducing the significant differences between the proportions (0% original concrete, 10% replacement, 15% replacement and 20% replacement). On the other hand, the compressive strength test established that the proportion that offered the best results was 10% replacement, since it maintained the compressive strength with respect to the original concrete, this due to the physical properties that were preserved in establishing the fineness module. The statistical analysis was able to determine from the mean diagram that there are no significant differences between the 10% and 15% replacements, that is, the proportions managed to maintain the compressive strength, otherwise it was observed in the multiple range test where the replacement 20% show a considerable drop in resistance.
