Análisis comparativo de peso y resistencia a la compresión entre hormigón tradicional y hormigón alternativo fabricado con agregados naturales

Abstract

The growth of the construction sector leads to an increase in the use of conventional aggregates such as stone and aggregate materials. To reduce the use of these materials, the replacement of the arid material was proposed in small quantities, with one that was of similar characteristics, but of an organic nature being used the Rice Husk and Banana Fiber as an object of study. This experimental work was intended to implement material of organic or plant origin for the realization of concretes as an alternative to reduce the use of materials from quarry extraction. For this purpose the physical and mechanical characteristics of the aggregates were analyzed through laboratory tests, the granular material was obtained from the Tuco León quarry located in Pasaje, it was made knowing the mixture dosages with material crushed with a maximum nominal size of 3,4", the organic materials like the rice husk was obtained of the sector La Cuca located in Arenillas, while the banana fiber was obtained from the Kimberly estate in the Union located in Machala. Ten doses were performed in total, replacing the sand in percentages of 2%, 4%, 6%, 8%, 10% with banana fiber and rice husk respectively, for the management of banana fiber was dried in the oven at a temperature of 105°C for 36 hours until it is perfectly moisture-free, the fiber should have been crushed in such a way that it did not occupy too much space within the dosage, the rice husk was used in its natural state, the calculation of the dosage was made through the ACI method obtaining a cement water ratio of 0.68.
