Abstract
This paper is focused on geotechnical behavior of municipal solid waste incineration ash stabilized with cement and fibre. In order to evaluate the effect of addition of cement and fibre on the compaction and strength behavior of municipal solid waste incineration (MSWI) ash, a series of tests were conducted. The polypropylene fibre of length 6, 12 and 18 mm were used in different proportions as 0.5, 0.75 and 1% by dry weight of whole mix specimens, whereas cement contents were taken as 2, 4, 6 and 8%. The mix specimens cured for 7, 14 and 28 days after which they were tested for unconfined compressive strength tests and split tensile strength tests. Additionally, the SEM and XRD tests were carried out during study in order to evaluate the surface morphological characteristics, and hydraulic compounds formed during the process. The test results showed decreased maximum dry unit weight and increased optimum moisture content when the MSWI ash incorporated with cement and fibre. The results also revealed that the fibre inclusion increased the strength of the MSWI ash specimens as well as that of the cement stabilized specimens due to change in behavior from brittle to ductile.
