Earthquake Response of Granulated Coal Ash by Online Testing
Abstract eng: Coal ashes discharged from coal-fired power plants have recently been gaining attention as a new form of geomaterials. They have been popularly used as ground materials for the improvement of unsuitable soil and for foam-mixed solidified soil. However, development of more applications is needed in the light of the enormous amount of coal ash generated. The present study was performed to confirm the applicability of granulated coal ash as reclamation material with adequate resistance against liquefaction during an earthquake. For this purpose, online pseudo-dynamic response tests were performed using a hollow torsional shear test apparatus. For comparison purposes, similar tests were performed using Toyoura sand, and the difference in the seismic response of the two materials is discussed. The results obtained clarified the behavior of granulated coal ash when subjected to cyclic loading due to earthquakes.
