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.

Rice husk ash (RHA) is an agricultural residue and has shown great potential for soil stabilization. However, the research on the utilization of RHA for soft soil improvement using cement deep mixing method is still limited and the efficiency of using different RHA types for soil improvement needs to be clarified. In this study, the effect of different RHA types on Atterberg limits, unconfined compressive strength (UCS), and elastic modulus (E50) of soil-cement mixtures will be investigated. Two types of RHA which obtained from open fire burning (RHA1) and burning in a furnace under controlled conditions of temperature and duration of burning (RHA2), were used for this study. The RHA contents from 0 to 15% and 10% cement of the dry weight of the soil were used to treat the soft soil. The research results show that the types of RHA insignificantly affect the change in Atterberg limits of cement-admixed soil. Regarding the soil strength, the RHA2 shows a higher efficiency in the enhancement of treated soil strength at 28 days of curing than the RHA1. The addition of 12% RHA2 to the cement-admixed soil can increase the UCS and E50 values of treated soil by more than 50%.

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.
