“…Significant improvement was also seen in soaked and unsoaked CBR values on addition of NaOH and KMnO 4 treated fibers. In a study conducted by Jairaj et al 53) , lime was found unsuitable when used with treated and untreated coir fiber. In this study, it was found that the properties of modified black cotton soil improved in initial days of curing but deteriorate with further increase in curing period.…”

Expansive soils usually face problems related to excessive expansion and contraction, high water retaining capacity, poor drainage, high compressibility and poor load transfer mechanism. The rate of failures in these soils is relatively high and these soils are considered as most vulnerable for construction purposes. The amendment of using waste materials in soil stabilization serves the purpose of limiting the high volume of waste generated from different sources. This in turn also restricts the consumption of natural resources which are conventionally used to stabilize the soil. Out of several waste materials generated from various sectors: agricultural, industrial, construction and demolition and mining, twenty-one highly generated but underutilized waste materials have been designated for review in this study. Their utilization as additives in soil stabilization as a partial or full replacement of conventional/traditional additives has been appraised in the present study. Among the various agricultural waste products considered, palm oil fuel ash (POFA) has been found to be the most effective with the optimum dose of 10 % -30 % in soil stabilization. Cement kiln dust (CKD) and iron ore tailings (IOT) with 50 % lime were found out to be effective with the optimum dosage of 20 % and 16 %, respectively. C&D waste was applicable in the range of 10 % -24 % in the presented research work owing to the variable characteristics of the source. This paper would be helpful to industry persons in adopting alternative additives and researchers in knowing the areas which require further research.

“…The behaviour and properties of soil significantly influence the economy, safety, and success of many civil engineering projects. Soil stabilisation and soil reinforcement are extensively used in many engineering structures to enhance geotechnical properties, such as the plasticity, durability, shear strength, density, and permeability of natural soils [1][2][3]. It is essential to consider all aspects of environmental control, including water pollution control, water resources, containment and waste disposal, and the mitigation of natural disasters effects such as earthquakes and landslides on structures.…”

Compressive and Shear Strengths of Coir Fibre Reinforced Activated Carbon Stabilised Lateritic Soil

et al. 2022

Constructing structures on lateritic soil is challenging in geotechnical engineering due to the various physical and geotechnical characteristics. Many studies investigated different stabiliser materials to strengthen the geotechnical parameters of lateritic soil. This study used activated carbon and coir fibre (ACF) to stabilise lateritic soils as an environmentally friendly binder. Experiments including the unconfined compressive strength (UCS) test and the direct shear test (DST) are performed to investigate the mechanical properties of ACF-stabilised soil for different percentages of activated carbon (AC). Before and after ACF stabilisation, microstructural characterisations of soil samples were performed using field emission scanning electron microscopy (FESEM) and surface-area analysis (BET). The experimental results demonstrate that 3% ACF can considerably enhance the compressive strength, while 2% ACF significantly improves the shear strength, of lateritic soil. Accordant to the UCS results, using fibre in AC-stabilised soil improves post-peak behaviour and residual strength. Moreover, 2% ACF can significantly improve shear strength by creating an interlocking matrix among AC, soil particles, and fibre. The microstructural characterisation based on the findings obtained by FESEM and BET analysis confirms that AC particles fill soil voids. AC restrains the soil movement when exposed to external stresses. In addition, the formation of gel in the stabilised soil matrix binds the soil particles, increasing the strength of the ACF-stabilised soil in comparison with untreated soil.
