| dc.description | El presente informe sobre un esfuerzo de investigación que buscó soluciones de construcción que ayuden a reducir la degradación ambiental. Para esto se decidió investigar el uso de mezclas de suelo - cemento - cáscara de arroz para obtener un material alternativo de construcción. Para conseguir este objetivo, los suelos fueran tratados con diferentes mezclas de cemento y cáscara de arroz, siendo posteriormente estudiadas sus propiedades físico-mecánicas. La cáscara de arroz fue fraccionada, tamizada y tratada en solución de cal; se estudiaron las dosificaciones posibles para las mezclas de suelo-cemento-cáscara de arroz a través de ensayos de compactación normal de Proctor, ensayos de compresión simple, de tracción a la compresión diametral, en las edades de 7 y 28 días y además se realizaron ensayos de absorción de agua. A partir de este estudio preliminar, se fabricaron ladrillos con las diferentes mezclas de suelo-cemento-cáscara de arroz los cuales, después de curados, fueron sometidos a ensayos de resistencia a la compresión simple a los 7, 28 y 60 días y a ensayos de absorción de agua. Después de determinadas las principales características físicas y mecánicas de todas las mezclas, se puede concluir que las del suelo arenoso con el agregado de un 12% de la combinación del cemento y la cáscara de arroz, se destacaron como materiales factibles a ser empleados en la fabricación de ladrillos prensados, los que podrían ser utilizados en construcciones e instalaciones rurales. | es-ES |
| dc.description | This work informs about a research effort with the aim of proposing construction solutions that help reducing the environmental degradation the researchstudied the utilization of rice husk added to mixtures of soil and cement to obtain an alternative construction material. For this purpose, the soil was treatedwith different amounts of cement and rice husk and then the physical and mechanical properties of each mix were studied. The rice husk preparationconsisted of grinding, sieving, and pre-treatment with a lime solution followed by physical analysis in laboratory conditions. The different mixtures of soil,cement and rice husk were tested for Proctor compaction, unconfined compression and splitting tensile strength at the age of 7 and 28 days as well as towater absorption. The soil-cement-husk mixtures presenting the best results in terms of mechanical strength were utilized for specimen brick manufacturing.Compressive strength tests at the age of 7, 28 and 60 days were applied to the specimens and the water absorption was measured. The obtained data wasthen statistically analyzed and the results showed that the sandy soil with the addition of 12% of the cement and rice husk combination was the best treatmentin terms of physical and mechanical properties, pointing out its promising use as an alternative material for brick be used in rural construction.This work informs about a research effort with the aim of proposing construction solutions that help reducing the environmental degradation the researchstudied the utilization of rice husk added to mixtures of soil and cement to obtain an alternative construction material.
