Utilization of Waste Steel Slag, Fly Ash, Glass Bottle Powder for Swamp Soil Stabilization

Abstract:

Limited land with good soil quality results in infrastructure being built in areas with unfavorable soil characteristics. development. Soil with unfavorable characteristics one of which is swamp land. Swamp soil needs to be stabilized if we want to build buildings on that land, the stabilizing material used can be silica waste or other binding materials. In this test, steel slag, fly ash, and glass bottle powder were used as the main stabilizers, with a fixed percentage of 20% steel slag and 20% fly ash, and glass bottle powder as an independent variable with a percentage of 0%. 5%, 10%, and 15%, and with the aging time of 0, 3, and 7 days. Testing the characteristics of Situ Rawa Arum, Jl. Kp. Tegal Wangi No. 62, Kec. Gerogol City of Cilegon Banten has poor soil carrying capacity with a CBR value of 1%. After stabilization using steel slag, fly ash, and glass bottle powder there was a significant change. The most optimum change in soil carrying capacity occurred in a mixture of 5% glass bottle powder + 20% steel slag + 20% fly ash with a CBR value of 31%.
