PHYSICAL PROPERTIES AND SHEAR STRENGTH OF BOILER SLAG
This study is about the determination of the physical and engineering properties of boiler slag. The boiler slag is a by-product that is obtained from the Tanjung Bin power plant. The source of reference for the use of boiler slag is minimal for this type of applications. However, this is an environmental suggestion to utilise the disposed of by-product from the ash pond. In this study, the properties of boiler slag are determined, such as the specific gravity, particle size distribution and shear strength. The specific gravity of boiler slag obtained was found to be 2.45, falls in the range provided by User Guidelines for Waste and By-product Materials in Pavement Construction by Federal Highway Administration. While, the shear strength for three samples tested were 73.78kN, 141.2kPa, and 285.9kPa. The internal friction angle of the sample obtained by the plotted graph of shear stress vs normal stress is 55°. The result obtained was analysed and concluded to acknowledge the capability of boiler slag as a construction material to be used in construction, mainly in pavement industries.
