Investigation of Characteristics and Role of Fly Ash as an Alternative Binder in Stabilization Process of Polluted Waste Sediment from Industrial Port

Ernesto Silitonga

Abstract


Due to the high demand of the management of waste sediment from industrial port in France. The reuse of this particular material is urgently needed to realize. The stabilization is one of the methods proposed. The high content of heavy metal in this waste makes it difficult to stabilize it just only with normal hydraulic binders. Fly ash utilized in this study is a byproduct of from local coalmines. The main idea is to maximize the utilization of waste material by stabilizing waste with a waste material. The application of the reuse of the waste sediment is as material in road construction work. First step is identifying the initial characteristics of waste sediment and binders used in this study. The chemical test is implemented as well to find out the heavy metal content in the waste. The next step is formulating the ideal composition of the binders in the mixtures. In order to verify the capabilities of stabilization process (with fly ash) to meet de needs on road construction is done by realizing several geotechnical tests. The result shows that the heavy metal content of the waste sediment is categorized in a medium level (non hazardous waste). The mixture with highest strength value is not exactly with the highest content of fly ash. The water sensitivity test confirmed that the mixture without any fly ash content couldn’t survive to mouillage-sechage cyclic test. . The Unconfined compressive strength and tensile test shows that the addition of fly ash clearly provides an additional performance especially at long term of curing age. The fly ash addition helps to improve the engineering properties and the result confirmed that the waste sediment stabilized with fly ash could and safe to be used as replacement material in sub base course in road pavement.
