Efectos de la ceniza y fibra de bagazo de caña de azúcar en propiedades de transferencia de calor y ruido aéreo en adobes

Abstract

Abstract: The present investigation consisted of comparing the thermo-acoustic properties of conventional adobes, compared to those made with ash and sugar cane bagasse fiber. Panel-type prismatic specimens with a side of 10cm and a thickness of 2cm were manufactured, with 4 types of mixtures: the sample made up of earth and water (T+A); the following mix earth with bagasse ash at 2% of the total volume of the panel (T+C); sample 3, made up of earth, ash and fiber (T+C+F) and the last, earth with bagasse fiber at 2.5% of the volume of the panel (T+C). 3 specimens were developed for each combination, obtaining 12 units, which were subjected to heat transfer and airborne noise tests. With this, it was determined that the mixture made up of earth and ash (T+C) is the one that has the best acoustic characteristics, reducing the amount of noise that passes through the sample by 17.75%. This sample (T+C) presents better thermal characteristics, since throughout the controlled time periods, this material reduces the heat transfer by 33.52%.
