Hormigón reforzado con fibra natural de caña de azúcar y su resistencia a la compresión.

Abstract

Currently, different studies have been developed to take advantage of unconventional aggregates in the preparation of concrete mixtures, in this case in particular the effects of natural sugarcane fiber have been analyzed as a measure of physical and mechanical characteristics in the concrete.This experimental work began with a previous bibliographical investigation of the dosage required for the preparation of concrete specimens that meet the requirements established in the regulations in force in the country. Once this information was studied, the sugarcane was processed, removing the natural fibers from its stem, then the fibers were cut and washed both in cold and hot water repeatedly and then dried naturally for a week, thus ensuring the total elimination of sugars and impurities of the cane. Finally, they were distributed homogeneously within the mixture in an equivalent of 2.37 kg / m3 depending on the weight of the cement. Analyzing the results obtained, relatively low variations were evidenced in relation to those presented by the concrete used for the control samples, both in workability and consistency. However, the trials showed that the improvements were remarkable in compressive strength, as it was shown that the natural fibers of sugarcane improve the mechanical response of concrete
