Geotechnical engineering can noticeably affect the sustainability of infrastructure development because of its beginning place in the construction practice. Utilization of waste materials for enhancing properties of the soil is a wise choice and is also one step towards accomplishing sustainable development. Application of by-products (viz., flay ash and rice husk ash) which could be defined as “sustainable materials”, find special place in the modern-day soil stabilization and modification exercise. The preset paper aims at enhancing properties of expansive soil with inclusion of industrial by-products namely Rice Husk ash and Fly Ash. Further the present paper focuses on improving geotechnical characteristics of fine sand upon reinforcing with ground shredded rubber tire. Fine sand has a low angle of internal friction and which in turn has low shear strength. Reuse of waste materials is one area of research which attempts to makes geotechnical engineering practice sustainable.

Deformation Properties

Geological disasters often occur due to expansion and shrinkage properties of expansive soil. This paper presents a cementitious material combined with rice husk ash (RHA) obtained from biomass power plants and lime to stabilize expansive soil. Based on compressive and flexural strength of RHA-lime mortars, blending ratio of RHA/lime was adopted as 4 : 1 by weight for soil stabilization. When mix proportion of RHA-lime mixture varied from 0% to 20%, specific surface area of stabilized expansive soil decreased dramatically and medium particle size increased. The deformation and strength properties of stabilized expansive soil were investigated through swelling test, consolidation test, unconfined compression test, direct shear test, and so on. With increase in RHA-lime content and curing time, deformation properties including swelling potential, swelling pressure, compression index, crack quantity, and fineness of expansive soil lowered remarkably; meanwhile, strength properties involving unconfined compressive strength, cohesion, and internal friction angle improved significantly. Considering engineering performance and cost, mix proportion of 15% and initial water content of 1.2 times optimum moisture content were recommended for stabilizing expansive soil. In addition, effectiveness of RHA-lime to stabilize expansive soil was achieved by replacement efficiency, coagulation reaction, and ion exchange.

Mineralogical Study

The paper presents the influences of different mix proportions of lime and rice husk ash (RHA) on compaction, strength properties, and durability characteristics of a local soil to evaluate the effectiveness of using RHA as a pozzolan to enhance the lime treatment of the soil. Mineralogical study was carried out also by using X-ray diffraction techniques to identify the reaction products that are responsible for the modification of the soil properties. In the mineralogical study, samples were analysed at different stages of curing. The results show that addition of RHA enhances not only the strength development but also the durability of the lime stabilized soil. Key words : soil stabilization, Atterberg limits, compaction test, unconfined compression test, X-ray diffraction.

Vital Role

Abstract During any construction on soil surface such as construction of road and airport pavements, compaction of the soil is required and soil stabilization plays a vital role. Various characteristics of soil should be optimized with different factors. Expansive soil has property of swelling when moisture content increases and shrinking when water gets evaporated. Rice husk is a major agricultural waste that is easily available in in India and is generally burnt to get rice husk ash (RHA). This study has been aimed to get dual benefit, first to stabilize expansive soil by addition of RHA and second to effectively utilize RHA, the agricultural waste. It has been observed that at 12% RHA in presence of 5% cement can be effectively used to improve plasticity of soil and CBR value resulting in effective soil stabilization. Thus, the research demonstrates that agricultural waste has efficient use in soil stabilization.

Strength Capacity

Construction activities on peat soils are found to be extremely difficult as the soil is profound as soft soil and has low shear strength and high moisture content. Due to alternating swelling and shrinkage nature, it causes serious damage to the structure above it. This happens due to repetition of drying and wetting of soil. Stabilization of soil is commonly applied to improve the mechanical properties of soil prior to soil engineering works. This soil improvement method is advantageous and effective one by using waste materials. Waste in our country is divided in various types and it includes domestic wastes, industrial wasters, agricultural wastes etc. Because of difficulties to diminish these wastes without affect to environment and surroundings, it can be used as a stabilizing agent in the soil. Therefore, this experimental study carried out to evaluate the effect of Rice Husk Ash (RHA) and sawdust on engineering properties of the peat soil. The properties such as compaction and unconfined compressive strength are determined separately with sawdust and added of RHA in peat soil at a variety of percentages (2.5%, 5% etc.) in addition small amount of constant rate of lime with 2% of the dry soil weight. By obtaining the results, it can deduce a promising and improving result in stabilizing the soil with sawdust and Rice Husk Ash in both economic and strength capacity. This will not only solve the waste disposal problem but also enhance the strength characteristics of soil significantly.
