Abstract
La presente tesis tuvo como objetivo evaluar la resistencia a la compresión del adobe
compactado con adición de diferentes niveles de cascara de arroz. La tierra utilizada
para la elaboración de las unidades fue extraída de la comunidad de Zungarococha,
de la Facultad de Agronomía, de la Universidad Nacional de la Amazonia Peruana.
Los porcentajes de cascara de arroz utilizados en la elaboración del adobe fueron de
30%, 40% y 50% con respecto a la cantidad de la muestra de suelo. Los resultados
del adobe demostraron un incremento de la resistencia a la compresión con los
valores promedios de 15.28 Kg/cm2, 16.35 Kg/cm2 15.52 Kg/cm2-
Los datos registrados para efectos del análisis de variancia, corresponden al secado
del adobe a temperatura ambiental desde el primer día con un peso inicial promedio
de 5.5 kg. para todas las unidades de adobe, siendo la diferencia numérica no
significativa del peso seco a los 15 días de oreado y secado al ambiente natural,
tiempo en que el peso se estabiliza y no muestra disminución de peso debido al
contenido de humedad.
La proporción 40% de cascarilla de arroz muestra menor peso seco (4.03 kg),
seguido de la proporción 30% y 50 %de cascarilla de arroz (4.20 kg) respectivamente.
This thesis aimed at evaluating the compressing resistance of the compacted adobe with the addition of different levels of rice shell. The land used for the production of the units was extracted from the community of Zungarococha, from the Faculty of Agronomy, of the National University of the Peruvian Amazon. The percentages of rice shell added in the adobe making were 30%, 40% and 50% with respect to the dry weight of the soil sample. The results of the adobe showed an increase in compression resistance with the average values of 15.28 Kg/cm2, 16.35 Kg/cm2 15.52 Kg/cm2- The data recorded for the purposes of the analysis of variance correspond to the drying of the adobe at ambient temperature from the first day with an average initial weight of 5.5 kg. for all adobe units, being the non-significant numerical difference in dry weight at 15 days of cooking and drying to the natural environment, time when the weight stabilizes and shows no weight loss due to moisture content. The 40% ratio of rice husk shows lower dry weight (4.03 kg), followed by the proportion 30% and 50% of rice husk (4.20 kg) respectively.
