“…Over the years, soil stabilization was achieved using ordinary Portland cement as a conventional method. High production costs, high energy use, and CO2 emissions, contributing to global warming, are all justifications for researchers to look for the most cost-effective and eco-friendly cement substitutes in soil stabilization [33,34]. Recently, utilization of waste materials for soil stabilization has been increasingly achieved by geotechnical engineers [35][36][37].…”

Over the years, investigating the behavior of soft soil, stabilized using different techniques, has been recognized as a critical priority for geotechnical engineers. Numerous soil constitutive models have been utilized to simulate stabilized soil behavior, improve strength and ductility, and analyze load-deformation responses. However, further investigation is required to study stabilized soil's time-dependent strength and stiffness, especially at an early curing age. Early strength and stiffness development is crucial in engineering construction for improving building quality and efficiency and minimizing crack risk. Furthermore, estimating UCS from an early age aid in safety evaluation and ground-improvement analysis. Researchers are increasingly recognizing palm oil fuel ash (POFA) as an eco-friendly alternative to traditional soil stabilizers due to its abundant availability. This study proposes an advanced concrete constitutive model to simulate the time-dependent strength and stiffness of POFA-stabilized and cement-stabilized soil due to pozzolanic interactions. The model accurately measures strength and stiffness improvement from an early curing age to 28 days using finite element analysis (FEA) before then comparing the experimental results. Based on the experimental results, the UCS values of palm oil fuel ash-stabilized soil grew to 3.18 MPa and 3.89 MPa after seven and 28 days with an optimum content of 30% (POFA): 10% Magnesium Oxide (MgO). It exhibited a significant increase in early strength with 64.02% compared with cement-stabilized soil. For stiffness results, a slight increment of 9.26% was observed. Employing FEM, the sensitivity of the parameters to stress-strain behavior was investigated. Finally, the validity of the concrete constitutive model to predict the time-dependent strength and stiffness of stabilized soil was proved. Doi: 10.28991/CEJ-SP2024-010-05 Full Text: PDF

In recent years, in developing nations, importance of village roads with sustainable and low-cost are gaining importance. In this study an attempt has been made to understand the strength and stiffness of mechanically altered soils. The locally available Lateritic soil and black cotton soil can be used in the construction field to improve the properties of soils for building foundations, roadways, and other engineering structures. The main goal of this study was to investigate the effects of mixing different percentages of red soil and black cotton soils on the physical and mechanical properties of the blended soil. Experimental investigation was carried to determine various properties such as shear strength, compressibility, water content, and differential swell index, of blended soils. The results of these tests were then compared to the properties of the individual soils to determine the effects of mechanically alteration on the overall properties of the soil. This experiment is important in the construction field as it allows engineers and contractors to determine the optimal mix of soils for specific construction projects. This experiment can be used to improve the overall soil quality in construction sites, which can lead to cost savings and improved durability of structures built on the site. Finally, the results thus obtained are trained to an Artificial Neural Network (ANN) and the relation between the engineering properties, UCS, and CBR are obtained. The prediction models show higher performance with correlation coefficients of 0.986 and 0.980, respectively. Overall, the blending of red soil and black cotton soil is an important experiment in the construction field that provides valuable information on the properties of blended soils and how they can be used in construction projects to improve the overall quality, durability, and stability of engineering structures.

This study investigates the usage options of Bitumen Emulsion (BE) mixtures composed entirely of Lateritic Clay Soils (LCS) using Calcined Sugarcane Bagasse Ash (CSCBA) as a filler. The LCS was chemically stabilized with 4% CSCBA to meet the plasticity index requirement of a maximum of 7% for BE stabilized materials as set out in the South African Bitumen Association (Sabita) Technical Guideline: Bitumen Stabilized Materials (TG2) and the Kenya Pavement Design Guideline for Low Volume Roads (TG1). The soil was then bound with a medium setting A4-60 anionic bitumen emulsion consisting of 60% base bitumen and 40% water. Varying proportions of BE (11%, 12%, 13%, 14%, and 15%) were mixed with LCS at a constant pre-mix water content of 12.9% to produce Marshall specimens cured for 72 hours at 40oC. The bulk density, dry density, soaked and unsoaked Indirect Tensile Strength (ITS), and Tensile Strength Ratio (TSR) were determined for the cured specimens. The optimum bitumen emulsion content was 13.82%, which gave the highest dry and wet ITS of 183.9 kPa and 132 kPa, respectively, and a TSR of 71%, meeting all specifications when compared to the TG2 and TG1 specifications. The compound also had reduced air voids, which when combined with a higher TSR, demonstrate resistance to moisture damage.
