-----------------------------------------------------------------------***---------------------------------------------------------------------Abstract: The challenges posed by silty soil in India challenges, researchers and engineers have been exploring

various techniques to improve the engineering properties of silty soil. One promising approach is the incorporation of additives such as cement, moorum, and fly ash into the soil matrix. Cement is widely recognized for its ability to improve soil strength and stability through the process of soil stabilization. Moorum, a locally available granular material, offers potential benefits in terms of enhancing the soil's mechanical properties. Fly ash, a byproduct of coal combustion, has also been found to possess pozzolanic properties and can contribute to soil stabilization.

have become increasingly apparent in recent years, affecting the stability and performance of various civil engineering structures. The expansive nature, low shear strength, and high compressibility of silty soils contribute to issues such as foundation failures, road pavement distress, and slope instability. This research endeavours to address the critical problem of silty soil in India by exploring innovative solutions for its stabilization. In this study, cement, moorum (a locally available granular material), and fly ash (a byproduct of coal combustion from thermal power plant) were added to silty soil in different proportions to improve its geotechnical properties. The experimental program involved conducting laboratory tests on various mixtures of silty soil, cement(2%,4%) , moorum (5%,10%), fly ash(5%,10%) and Combination of fly ash(5%,10%), Moorum (5%,10%) and Cement(2%,4%) . The tests included Liquid Limit tests, Plastic Limit tests, Heavy Compaction tests and California Bearing Ratio (CBR) tests. The aim was to investigate the effects of the soil-cement- moorum-fly ash mixtures on parameters such as maximum dry density, optimum moisture content, CBR values. The results of the experimental investigation revealed that the addition of cement, moorum, and fly ash significantly improved the engineering properties of silty soil. The maximum dry density increased, indicating better compaction characteristics, and also the optimum moisture content increased. The CBR values and compressive strength of the soil mixtures increased with increasing percentages of cement, moorum, and fly ash.

According to the literature (Amu et al. 2005) had used (Class- F) fly ash and cement for stabilization of Silty soil. It was found that stabilizing effect of 9% cement and 3% fly ash was better than the stabilizing effect 12% cement. (Cokca 2001;Nalbantoglu 2004;Mishra et al.2005) had studied effect of class- C fly ash on different engineering properties of expansive soil and had found varied success. (Sharma and Gupta 2013) had investigated the effect of fly ash(class-F) on sand stabilized black cotton soil based on compaction and CBR test the optimum proportion of soil: sand :fly ash was found to be 63:27:15. (Gopala Krishna et al. 2013) had studied the effect of fly ash (class-F) and zycosyl on soaked and unsoaked CBR of black cotton soil, the highest unsoaked CBR was obtained at 2% zycosyl with 3% fly ash and highest soaked CBR was obtained at 2% zycosyl with 4% fly ash. (Amadi and Lubem 2014) had investigated the effect of cement kiln dust (up to 16%) on10% quarry fine stabilized black cotton soil and had found reduction in IP, maximum dry density (MDD) and increase in optimum moisture content (OMC) and CBR. (Amadi and Lubem 2014) had investigated the effect of cement kiln dust (up to 16%) on10% quarry fine stabilized black cotton soil and had found reduction in IP, maximum dry density (MDD) and increase in optimum moisture content (OMC) and CBR.

Introduction

II.

Silty soil is a common soil type found in many regions around the world. It is characterized by its fine particle size and moderate plasticity. However, silty soil exhibits several geotechnical challenges due to its low strength, high compressibility, and susceptibility to erosion. These limitations can pose significant obstacles in construction projects, particularly when load-bearing capacity, stability, and durability are crucial factors. To address these
