SUMMARY
Peat is well known for their inherent high moisture content, porosity and compressibility. This soil type requires pre-treatment, such as solidification, to improve the engineering properties before loads from infrastructure above ground can be applied. There are three decomposition levels for the peat soil, namely fabric, hemic and sapric peat. In the present study, the soil samples were treated using ordinary Portland cement and coal ashes etrieved from the coal power plant. The peat soil was mixed with bottom ash and fly ash using four formulations. The microstructure…
