| description |
The investigation evaluated the strength benefits obtained by amending cement stabilization of an expansive soil by using saw dust ash (SDA), a waste generated in wood milling industries due to burning. The experimental program involved the preparation of cylindrical specimens of size 38 mm x 76mm for evaluating the unconfined compression strength (UCS) of the cement stabilized and amended samples cured for varying periods of 2 hours, 7, 14 and 28 days. Two cement contents of 2% and 6% by weight of soil were adopted to stabilize the soil. The SDA amended cement stabilized samples adopted SDA contents of 5%, 10% and 20% by weight of soil. Strength gain trends for the amended samples were also fitted based on the results of the UCS tests. In order to analyse benefits in pavement design and thickness reduction, the UCS values were used to predict the CBR value of the specimens based on which the reduction in pavement thickness was calculated for different traffic densities. The investigation revealed that 5% SDA amendment of cement stabilization can result in up to 26% increase in early strength and 20% increase in delayed strength. Based on the predicted CBR values, pavement thickness can be reduced up to 8.3%. |

El programa experimental consistió en la preparación de muestras cilíndricas de tamaño 38 mm x 76 mm para evaluar la resistencia a la compresión no confinada (UCS) del cemento estabilizado y las muestras modificadas curadas por períodos variables de 2 horas, 7, 14 y 28 días. Se adoptaron dos contenidos de cemento de 2% y 6% en peso de suelo para estabilizar el suelo. Las muestras estabilizadas de cemento modificadas por SDA adoptaron contenidos de SDA del 5%, 10% y 20% en peso del suelo. Las tendencias de aumento de la fuerza para las muestras modificadas también se ajustaron en función de los resultados de las pruebas de UCS. Con el fin de analizar los beneficios en el diseño del pavimento y la reducción del espesor, los valores de UCS se usaron para predecir el valor CBR de los especímenes en base a los cuales se calculó la reducción del espesor del pavimento para diferentes densidades de tráfico. La investigación reveló que la enmienda 5% SDA de la estabilización del cemento puede dar como resultado un aumento de hasta el 26% en la resistencia temprana y un aumento del 20% en la resistencia retardada. Según los valores de CBR previstos, el grosor del pavimento se puede reducir hasta el 8.3%.application/pdfapplication/xmlengengUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/8790/7287https://revistas.uptc.edu.co/index.php/ingenieria/article/view/8790/7503https://revistas.uptc.edu.co/index.php/ingenieria/article/view/8790/7532Revista Facultad de Ingeniería; Vol. 28 No. 50 (2019); 44-61Revista Facultad de Ingeniería; Vol. 28 Núm. 50 (2019); 44-612357-53280121-1129ashroadssoilstrengthwaste managementwaste materialcaminoscenizamaterial de desechoresistenciasueloStrength benefit of sawdust/wood ash amendment in cement stabilization of an expansive soilBeneficio de la resistencia de la enmienda al aserrín / ceniza de madera en la estabilización de cemento de un suelo expansivoresearchinvestigacióninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a125http://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/access_right/c_abf42http://purl.org/coar/access_right/c_abf2N.A.N.A.James, Jijo001/14231oai:repositorio.uptc.edu.co:001/142312025-07-18 11:53:14.37metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
