Effect of Marble Dust on Strength Characteristics of Rice Husk Stabilized Soil
The construction expenses can be widely reduced by selecting locally available resources for the lowermost layers of the pavement. In the present urbanization and industrialization circumstance, which has formed several hazardous and non-perilous wastes. This promotes draining landfill space, soil contamination, and many different dangerous effects; henceforth in this study use of waste (i.e., Rice husk ash) for enhancing the soil properties is made. In the present study influence of Marble dust on the quality characteristics of Rice husk ash stabilized expansive soil to increase the features of subgrade soil were determined. Atterberg’slimit, compaction, unconfined compressive strength (UCS), direct shear strength and California bearing ratio (CBR) experiments were carried out on the specimens of native soil and expansive soil with stabilizers. The optimum percentage of RHA was found to be 10% based on UCS tests. Marble dust was added to RHA stabilized expansive soil up to 30%, by dry weight of the soil, at an increment of 5%. The maximum dry density (MDD) of expansive soil goes on increasing up to 25% and optimum moisture content (OMC) goes on decreasing irrespective of the percentage of the addition of marble dust to RHA stabilized expansive soil. The UCS, direct shear strength and soaked CBR of RHA stabilized expansive soil increased up to 15% addition of marble dust; the cohesion clearly increased. The UCS and CBR of the mixtures were 120.05 and 199.42% greater than for the untreated soil. Further addition of marble dust had negative effects on these properties. The results established less value of strength parameters for expansive soil, but after the stabilization expansive soil indicated increased value of UCC, Shear Strength and CBR. For better stabilization result, the optimal percentage of Soil: Rice husk ash: Marble dust was found to be 75: 10: 15.
