Activation Of Fly Ash-Lime Reactions By Curing At Elevated Temperature And By Addition Of Phosphogypsum
(2013-06-04)Pozzolanic reactions play a key role in improving the compressive strengths of compacted fly ash-lime specimens. Based on studies performed with cement amended fly ash (FA), activation of fly ash-lime pozzolanic reactions ... -
Characterization And Lime Stabilization Studies On Artificially Lead Contaminated Soils
(2011-07-08)Hazardous waste substances are solid, semi-solid or non-aqueous liquids that exhibit characteristics of corrosivity, reactivity, ignitability, toxicity and infectious property. Major available options for management of ... -
CHM (Chemo-Hydro-Mechanical) Behavior of Barmer-1 Bentonite in the Context of Deep Geological Repositories for Safe Disposal of Nuclear Waste
(2018-03-21)Deep geological repository (DGR) for disposal of high-level radioactive waste (HLW) is designed to rely on successive superimposed barrier systems to isolate the waste from the biosphere. This multiple barrier system ... -
Collapse Behaviour Of Red Soils Of Bangalore District
(Indian Institute of Science, 2006-07-17)Collapse phenomenon is exhibited by two types of residual soils. The first category of collapsing residual soils is believed to be transported soils that have undergone post-depositional pedogenesis. The second category ... -
Engineering Behaviour Of Ash-Modified Soils Of Karnataka
(Indian Institute of Science, 2007-02-22)During a survey of black cotton soil zones of Karnataka, indigenously stabilized black cotton soil deposits were encountered in Belgaum, Bijapur, Bagalkot and Gadag Districts of Karnataka. These modified black cotton soils ... -
Evaluation of Btex Contamination in Bengaluru Groundwater and Remediation of Contaminated Water Samples
BTEX (benzene, toluene, ethylbenzene, and xylene isomers) are monoaromatic, volatile organic compounds (VOCs) with single benzene ring and various degree of alkylation. US EPA classifies benzene and TEX (toluene, ethylbenzene, ... -
Extra-cellular Polysaccharides and Microbially Induced Carbonate Cementation Using Indigenous Microbes in Cattle Manure
Soft soils are composed of large portions of silts and clay and are characterized by low strength and high compressibility owing to their high-water content. Biocementation techniques are emerging as a strong alternative ... -
Factors Influencing Contaminant Transport in Vadose Zone of Near Surface Radioactive Waste Disposal Facility
Radioactive waste is generally classified as low and intermediate level waste (LILW) and high-level waste (HLW), based on their level of radioactivity and the time taken for decay. The low and intermediate level ... -
Fate and Remediation of Ammonium-n In Pit Toilet Blackwater
Pit toilets satisfy the sanitation requirement in regions with no access to piped sewerage facilities. Black water discharged from pit toilets is a major source of groundwater pollution. The primary focus of the thesis is ... -
Granular Media Supported Microbial Remediation of Nitrate Contaminated Drinking Water
(2018-01-11)Increasing nitrate concentration in ground water from improper disposal of sewage and excessive use of fertilizers is deleterious to human health as ingestion of nitrate contaminated water can cause methaemoglobinemia in ... -
Influence of Chemo-Mechanical Factors on Compression and Undrained Strengths of Soft Kaolinites Prepared using Synthetic Seawater
(2017-11-28)Marine clay deposits are characterized by very soft to soft consistencies (undrained strength 1-50 kPa), presence of saline pore solution and low-swelling clays. Besides, loss of metastable structure on disturbance, poor ... -
Influence Of Osmotic Suction On The Swell And Compression Behaviour Of Compacted Expansive Clays
(2008-11-03)Total suction of unsaturated soils is contributed by matric and osmotic suctions. Matric suction arises from capillary actions in the soil structure and varies with changes in moisture content of the soil. Pore fluid ... -
Influence of Permeation of Synthetic Groundwater Solutions on the Hydro-Mechanical Proerties of Barmer Bentonite
(2018-04-11)The deep geological repository concept is based on “engineered barriers systems (EBS)” that are constructed in the repository and “natural barriers” provided by the surrounding geological environment. The EBS comprises of ... -
A Magnesia Based Sustainable Method For De-Fluoridation Of Contaminated Groundwater
(2010-10-14)Groundwater is a major and sometimes lone source of drinking water worldwide. The chemical composition of groundwater is a combined product of the composition of water that enters the aquifer and its reaction with various ... -
Role of Physico-chemical Processes And Micro-structural Features in Influencing Moisture Loss and Engineering Properties Of Compacted Residual Soils Exposed To Environmental Relative Humidity
The moisture content of residual soils above the water table, and near ground surface (≤ 6 m) is influenced by the environmental relative humidity (RH). The focus of this thesis is to examine the physico-chemical and ... -
Stabilisation Of Black Cotton Soil By Lime Piles
(Indian Institute of Science, 2006-07-07)Modification of black cotton soils by chemical admixtures is a common method for stabilizing the swell-shrink tendency of expansive soils. Advantages of chemical stabilization are that they reduce the swell-shrink tendency ... -
Studies on Modified Clay Additives to Impart Iodide Sorption Capacity to Bentonite in the Context of Safe Disposal of High Level Nuclear Waste
(2018-03-03)It is a generally agreed internationally that high level nuclear wastes containing long-lived radioactive wastes should be disposed in deep and stable geological formations that are 500-1000 m below ground level. Deep ... -
Synthesis and Characterization of Geopolymers as Construction Materials
(2018-01-09)Geopolymers are a relatively new class of materials that have many broad applications, including use as substitute for ordinary Portland cement (OPC), use in soil stabilisation, fire resistant panels, refractory cements, ...
