Study on strength behavior of cement stabilized sludge reinforced with waste cornsilk fiber

Abstract: This study was carried out to investigate the strength behavior of cemented sludge reinforced with cornsilk fiber considered as a by-product from corn. Hence, a series of unconfined compression test was conducted at different levels of water, cement, and fiber content. Water contents considered in this study were 40, 50, and 60%; cement content used for sludge stabilization was changed from 5 to 40 kg/m3; meanwhile, fiber content was used at different levels from 5 to 30 kg/m3. In addition, the relationship between failure strength and the amount of water, cement, and fiber was investigated in the present work. The experiment results showed that there was an improvement in failure strength, failure strain, ductility, and stiffness with fiber inclusion. Besides, stiffness improvement was based on the amount of cement used. The relationship between failure strength with and without fiber inclusion and water, fiber, and cement content was described as following power or exponential function with a strong correlation coefficient. It was concluded that there was a good performance of cornsilk fiber in reinforcing cemented sludge. Furthermore, the utilization of waste material to modify soft soil or sludge will bring about many benefits not only for geotechnical engineering but also for the environment and social economy.

Cold in-place recycling and full-depth strengthening of clay-till subgrade soils: results with cementitious waste products in northern climates

Abstract: Saskatchewan is experiencing significant increases in commercial truck traffic due to grain transportation rationalization, consolidation of the rural grain elevator system, rural economic diversification, and expansion of resource industries. Although increasing truck traffic has long-term implications for the primary pavement system, significant increases hold immediate implications for thin paved roads; many were not originally designed to accommodate heavily loaded commercial trucks. There is a clear need to strengthen many Saskatchewan thin pavements. However, conventional structural strengthening typically involves regrading and granular subbase-base overlay systems, often too expensive because of the cost associated with aggregate hauls and regrading. As a result, the Saskatchewan Department of Highways and Transportation is investigating the use of cold in-place recycling and full-depth cementitious stabilization to strengthen Saskatchewan thin pavements. To this end, industrial waste coproducts such as coal fly ash, bottom ash, and kiln dusts are being investigated as structural cementitious soil stabilizers. The results are presented from preconstruction site investigation methods, laboratory materials characterization, and in situ quality assurance test results. Field performance after 2 years shows cold in-place recycling and cementitious stabilization to be a technically and economically feasible solution for strengthening Saskatchewan thin paved roads built on clay-till subgrades.

Soil stabilization compositions

Abstract: Hydraulically applied fiber matrix compositions for use on soils include a water-soluble, crosslinkable, hydratable gum, and a compound capable of crosslinking the water-soluble, crosslinkable, hydratable gum. The compositions may further include hydrocolloids and mulch. The hydraulically applied fiber matrix compositions are useful for hydroseeding and soil stabilization.
