Análisis comparativo de la resistencia a compresión del hormigón tradicional con hormigón al emplear biomasa natural torrefactada

Abstract

In order to make the most of renewable resources and innovate concrete with unusual materials, this experimental work included the production of a traditional conventional concrete and a concrete with the addition of natural biomass ash torrefied in 5, 10, 15 and 25 percent for your comparison. Laboratory tests of all the aggregates that make up the concrete mixture were carried out, being of granulometry, specific weight and absorption capacity. Once the properties of the aggregates were determined, the dosage was carried out using the Optimal Density method, where the elaboration of 45 cylindrical specimens was included, the same ones that were evaluated at 7, 14 and 28 days of age. Once the concrete specimens were made, the real density was analyzed in the fresh state and in the hardened state, later the compressive strength was determined, verifying how the torrefied natural biomass influences the properties of the concrete. The results obtained showed that the densities were optimal since they were within the ranges established for ordinary concrete; In terms of compressive strength, the addition of torrefied natural biomass increased at early ages in certain percentages much more than traditional concrete. Finally, the concrete that had a higher resistance to compression was the concrete with the addition of 10 percent of natural biomass, demonstrating an improvement in the resistance to compression without losing the properties that characterize a concrete that is of good quality.
