Abstract

The geotechnical properties of untreated MSW ash and the MSW ash treated with fiber and cement were investigated through a series of laboratory tests like compaction, unconfined compressive strength (UCS), and split tensile strength (STS) with different mixing proportions of fiber and cement. The physical characteristics of MSW ash are similar to those of silty sand, with a specific gravity of 2.26. The combination of fiber and cement is capable of improving the compaction behavior of MSW ash by increasing its strength and reducing its tendency to deform or crack under the load. It is observed from the test study that the addition of 0.5% fiber of 12 mm length with 8% cement by weight of MSW ash mix gives the optimum result in terms of UCS and STS as compared to untreated MSW ash. The increment in cohesion (c) and angle of internal friction (ϕ) is associated with the increment in cement and fiber content, respectively. An improvement factor (If) is defined to determine the percentage increment in the value of UCS and STS.
