Compressibility behavior of marine clay treated by combination of coal ash and cement

In the geotechnical field, any soft ground area that has construction on it will face a major challenge. A lot of engineering problems could arise either during or after the construction phase due to low shear strength and high compressibility of this soil in the form of excessive settlement, slo...
