Engineering Properties of Mangking Sandstone

Abstract

This project was intended to characterize the engineering properties of Mangking Sandstone Formation in Maran, Pahang. The main lithology is fine-grained white to light grey sandstone. The engineering properties of Mangking Sandstone was assessed by applying geological technique which is discontinuity survey and geomechanical techniques including Schmidt Hammer test, Acoustic Velocity test, Uniaxial Compressive Strength (UCS) test, Brazilian Tensile Strength test and Point Load Strength test. The Rock Mass Rating (RMR) system was applied to the rock mass based on its geological discontinuity and geomechanical information to assess the quality of the rock. Slope Mass Rating (SMR) was applied to assess the stability of the slope. The RMR values range from 73 to 78 which place the Mangking Sandstone in Maran area in Class II (good rock). The SMR values place the rock slope of Mangking Sandstone in Maran area in Class II (stable slope).
