Synthesis and Leaching of Zirconium-rich Alkali-resistant Glasses Containing Heavy Metals Present in Fly Ashes Incineration |Chapter 4 | Chemical and Materials Sciences: Research Findings Vol. 6

 

Glasses containing zirconium are used to produce glass fibres due to their alkali-resistant nature. The presence of zirconium slows the deterioration of the glasses. This study developed a process for producing alkali-resistant zirconium-containing glasses for use as a heavy metal retention matrix contained in fly ashes. These alkali-resistant zirconium-containing glasses were synthesised to undergo leaching tests. To synthesize these alkali-resistant glasses, 5 glass compositions were developed: two alkali-resistant model glasses type CEMFIL, V1 (with zirconium and without heavy metals) and V2 (with zirconium and heavy metals) and three glasses of fly ashes V3 (without zirconium and with heavy metals), V4 (with 30 % of V3, zirconium and heavy metals) and V5 (with 60% of V3, zirconium and heavy metals). V4 and V5 were obtained using V3 as raw material and supplementing with SiO2, ZrO2 and Na2O to give them alkali-resistant properties. Chemical composition of the various glasses was determined by a micro-analyser with an ion probe or electron microprobe of brand CAMECA SX50 with a potential difference of about 10 kV at Paris VI University. Differential thermal analyses, structural analyses, as well as the observation of the surface of the glasses were carried out at the CNRS/CEMHTI laboratory in Orléans. Differential thermal analysis showed a glass transition temperature Tg of 656°C for V1, 616°C for V2, 615°C for V3, 641°C for V4 and 664°C for V5. Extremely small peaks of alumina have been observed on the V1, V2 and V3 glasses and peaks of ZrO2 only on the V5 glass. Surface analysis of glasses showed that they were essentially homogeneous, although we noted the presence of some heterogeneities: V1 and V2 with small crystals of ZrO2, V3 had a slight crystallisation of Fe chromite spinel (CrO4), and V5 contained large crystals rich in zirconium. Glasses leaching in basic medium led to the development of hydrated film on the glass surface characterised by hydrogen enrichment and sodium depletion irrespective of the glass. After static leaching tests in a basic medium, SEM and electron microprobe analyses revealed that all glasses were covered with a weathering film. These weathering films were enriched in zirconium (V1, V2, V4, and V5) and depleted in Na. Glasses V4 and V5 had the most zirconium-enriched alteration films and also appeared to be the least affected.

Effect of Fly Ash and Ground Granulated Blast Furnace Slag (GGBS) with Fibres on Fresh and Hardened Properties of High-Performance Self-Compacting Concrete | Chapter 6 | Engineering Research: Perspectives on Recent Advances Vol. 8

High Performance Self-Compacting Concrete (HPSCC) has been one of the very important developments in the building industry. The analysis of supplementary cementation materials, i.e. Fly ash and Ground Granulated Blast Furnace Slag (GGBS), on Self-Compacting High-Performance Concrete was done in this study. The High Performance Self-Compacting Concrete makes it suitable for placing in difficult sections and conditions in members with congested reinforcement. The fresh and hardened properties of Special concrete - High Performance Self Compacting Concrete (HPSCC) studied in this work. The work studied has been focused on the Fly ash and GGBS effect with fibres on mix proportion and concrete in the hardened state. The Ultimate Strength - compression strength, Split Tensile Strength and Flexural Strength with replacement of Polypropylene fibres range of 0% -1.5% in 0.5 intervals and with various percentages of fly Ash and GGBS combination and behaviour of fibre under loading was found. The obtained values from this study are useful in determining design characteristics of HPSCC with fibre (polypropylene) sections. In this study, Fly Ash improved the fresh properties of concrete, while GGBS led to a reduction in workability.

Investigation of Fresh and Hardened Properties of Self-Compacting Concrete Using Calcite and Fly Ash as Supplementary Cementitious Materials | Chapter 4 | Engineering Research: Perspectives on Recent Advances Vol. 2

Concrete is the second most widely consumed building material in the world because of its beauty, strength and durability. In an era of increased attention to the environmental impact of construction, engineered concrete performs well when compared to other building materials. This study evaluates the use of a green material such as fly ash and calcite as Supplementary Cementitious Material (SCMs) in manufacturing of Self Compacting Concrete (SCC). The main objective of this study is to show the number of ways how the concrete industry can increase its compliance with the demands of sustainable development. Most recent research on SCMs has focused on a few areas: exploring new materials, increasing replacement amounts, developing better test methods, treating or modifying materials, and using additives to improve performance. Experimental investigation to check the feasibility of Fly ash and Calcite combination as SCMs in self compacting Concrete and its effect on workability and Harden Properties is checked. The study concluded that the elimination of vibrating equipment improves environment protection near construction and precast sites where concrete is being placed, reducing the exposure of workers to noise and vibration. In SCC, there is no chance of honeycomb, hence it gives a superior surface finish.

Stabilization of Expansive Soils with Lime and Fly Ash| Book Publisher International

 The expansive soils, popularly known as Black cotton soils in India are very problematic as they are poor material for foundation as well was construction.  Structures resting on expansive soils are subjected severe distress due to ground movement caused by the swelling and shrinkage of soils. Normally the types of foundations vary depending upon the availability of soil strata as well as cost involvement. Some times, it is essential to build a heavy structure over a weak soil, in such situation improvement of bearing capacity of soil by some suitable methods becomes necessary. The techniques generally adopted are stabilization and reinforcement of the soil.

The stabilization of soil by admixing some stabilizing agent has an effective ground improvement because of its easy adoptability and cost effectiveness.  If the admixing material is available in abundance at free of cost, it will reduce construction cost.

Mixing of lime is one of the methods to stabilize the expansive soils. With mixing of lime, the properties like swelling/shrinkage get reduced and some engineering properties are improved.

Fly ash, an industrial waste of thermal power plants has many geotechnical uses. The case study is on stabilization stabilization of expansive soils with lime and fly ash is presented.

The behavior of soil has been studied using different percentage of fly ash with the combination of lime. From the case study results it is found that engineering properties of expansive soil improves with the addition of lime and fly ash.  Swelling and shrinkage is effectively reduced.  With the addition of fly ash, the same results can be obtained at lower percentage of lime.

State-of-the-art Technology to Stabilize Heavy Metal in Municipal Solid Waste Incineration Fly Ash Using Natural Zeolite | Chapter 1 | Novel Perspectives of Geography, Environment and Earth Sciences Vol. 6

 Stabilizing difficult metals in Municipal Solid Waste Incineration (MSWI) fly ruins by using open zeolite is one of the state-of-the-skill technologies. The current study attracted on the sorption process of heavy metals by requesting mordenite, an inexpensive open zeolite adsorbent, and assessing the productiveness of the treatment of fly ruins. Batch experiments were conducted to review the effects of the powerful parameters, to a degree the initial ore ion concentration, the liquid-to-solid (L/S) percentage, the dosage of the adsorbent, and the evenness concentration of the mineral, on the immobilization of Pb2+ and Zn2+. Heavy metal counterweight efficiency increased accompanying increasing the portion of drug or other consumable of mordenite, influenced for one media-distinguishing surface area. Heavy metal adsorption is from various adsorption processes and ion exchange mechanisms. The Langmuir and Freundlich isotherm models were examined using the adsorption dossier. The adsorption process is better in the Freundlich isotherm model with a extreme determination cooperative (R2), especially for the adsorption of Pb2+. The effects raise hopes for the use of mordenite as a low-cost substance to treat MSWI flee ash. The verdicts indicate that harmonized (Pb2+ and Zn2+) immobilization by mordenite is technically doable and seems expected very effective. Furthermore, treated flee ash can be secondhand as a construction material.

Corrosion Performance of Steel Embedded in Activated Fly Ash Concrete | Chapter 5 | Techniques and Innovation in Engineering Research Vol. 9

 Cement actual is the most coarse construction material used in foundation projects because of allure versatility. Fly ash is individual among the usually used not organic admixtures as it is available in large quantities in many underdeveloped countries. The Ministry of Power, Government of India, estimates that 600 million tons of flee ash will stem from thermal power plants by 2031-2032, that is a major concern for the surroundings. The use of fly ash as a construction material is largely contingent upon its not organic structure and pozzalonic property. Different plans of activation can help these two properties of flee ash. This paper focuses on the chemical incitement of fly ruins with CaO and Na2SiO3, and the corrosion potential of chemically triggered fly ruins concrete against consuming environments is demonstrated by acid opposition tests, impressed power studies, and permeability studies.

Stabilization of Expansive Soil with Various Admixtures: A Brief Review | Chapter 09 | Novel Perspectives of Engineering Research Vol. 2

 The major goal of this research is to critically evaluate admixtures for expanding soil stability. Expansive soil, also known as clayey soil, can change its volume when water is available, causing swelling and shrinkage. Borrow earth is difficult to get by in urban places, and it must be hauled in from afar. Large regions are frequently covered in extremely flexible and expansive soil that is unsuitable for this purpose. Because of its low strength and high expansion, it causes damage to building structures and road pavements. Admixtures can improve the soil qualities in a negative way, stabilising clayey soil. Because of the cationic exchange in lime stabilisation, which promotes agglomeration and flocculation of the soil, it has a substantial impact on several parameters of expansive soil, including plasticity index, compaction, swell potential, clay fraction reduction, and silt and sand fraction increase.

Performance Evaluation of Reinforced Geopolymer Concrete as Earthquake Resistant Composite | Chapter 6 | New Approaches in Engineering Research Vol. 15

With the increasing challenges of ground vibrations due to seismic activity and the ever-increasing threat of blast loadings on structures, it has become more than a simple necessity to incorporate robust design strengths into structures without compromising serviceability life. When structural elements' ability to absorb and disperse energy through post elastic deformations subjected to multiple cycles of these loading is naturally incorporated at cheap cost, their performance is well acknowledged. The single controlling property for a structural element's healthy performance is its flexural element's ductility. Although several elements contribute to the ductility of Reinforced Geopolymer Concrete (RGPC), low calcium-based fly ash and GGBS have chemical proportions that allow RGPC to generate significant ductility when mixed in an intelligent way that meets structural and economic requirements. The impact of low calcium fly ash, GGBS, River sand, M-sand, Steel Grade, manufactured fibres, and natural fibres on RGPC ductility is investigated in this study using load testing 51 with reinforced flexural elements. Similar tests on the flexural ductilities of Ordinary Portland Cement based flexural elements conducted by other researchers show that Reinforced Geopolymer Concrete Structural Elements are extremely comparable and appreciated.

Preparation and Characterization of Glass-ceramic Composites from South African Coal Fly Ash: A Recent Study| Chapter 10 | Advanced Aspects of Engineering Research Vol. 12

 Despite the fact that fly ash is mostly used in the construction industry in South Africa, a considerable amount of it is nevertheless dumped. Fly ash devitrification for the production of glass-ceramic composites has steadily become one of the applications being investigated internationally. The exploration of creating glass-ceramic composites from fly ash, various amounts of beverage waste glass, and magnesium oxide as key raw materials is reported in this paper. Fly ash was melted to make glasses. An arc furnace is used to melt the metal and its additives. The glasses were crystallised using a double-staged thermal treatment to generate glassceramic composites based on their behaviour when subjected to differential thermal analysis. X-ray diffraction, scanning electron microscopy, mechanical, and chemical tests were used to evaluate the composition and behaviour of the glass-ceramic composites. As the magnesium oxide content in the glass-ceramic composites grew, so did the crystal content. The amount of content was increased. As the magnesium oxide content increased, the desirable diopside phase diminished, resulting in the development of forsterite and anorthite as the major and second major phases, respectively. Chemically and thermally resistant, the glass-ceramic composites with lower magnesium oxide content also displayed good cold compressive strength.

Recent Research of Lime Mortar and FAL-G with Urea| Chapter 9 | Advanced Aspects of Engineering Research Vol. 14

 Urine is used to improve the characteristics of traditional Indian lime mortar. To provide a more sanitary option, urea (fertiliser) was employed instead of urine in this investigation. Urea is applied in various proportions, including 1 percent, 2 percent, 3 percent, 4 percent, and 5 percent, using Lime Mortar 1:3 and FALG paste. Weight density, water absorption, and compressive strength were all tested on the resultant composites, which were cast into 50-square-centimeter cubes. The output of plain FAL-G cubes and simple lime mortar cubes were compared. With 3 percent urea, FAL-G has greater characteristics than lime mortar.

The work analysed the navy's and coastguards' maritime protection policies in order to assess the spatial coverage of the gained maritime territory under the current exclusive economic zone legal regime. The evaluation variables include the state's coastal resources, such as renewable resources like fish and nonrenewable underwater resources like oil. The freedom fields, such as maritime traffic, pipelines, underwater cables, and air traffic, are among the others. To evaluate the level of protection, regression analytical tools were used during the study. Based on the research results, recommendations for improving the quality of protection in the region were made. As part of Nigeria's maritime protection policy, the concepts of sea base and sea shield were studied. The two systems of sea shield and sea bases were used to examine documented maritime security problems in the region. Then, for the good of the whole system, further recommendations were made. For the world's most advanced nations engaged in anti-piracy activities in the world's maritime realms, a re-engineering of the new logistics operations approach was proposed. The superiority of security forces of countries engaged in anti-piracy operations was stressed. It was determined that mixing sea and air logistics would yield superior maritime results.

Unique Solution for Mechanical and Energy Retrofit of Existing Buildings by Means of a New Fabric Reinforced Geopolymer Mortar (FRGM) | Chapter 12 | Current Perspectives on Chemical Sciences Vol. 4

For the most part, the built heritage is ancient and thus involves engineering studies to develop the most effective retrofit system to enhance both mechanical and energy efficiency. In reality, the inadequacy of existing systems has been illustrated by recent disasters. Only think of the earthquakes that have weakened the structures more or less significantly; or the thermal insulation capability of buildings constructed over 50 years ago has been heavily challenged by climate change. In order to solve these problems independently, various interventions are widely proposed. Reasonable disadvantages, however, occur when direct contact with the target member is needed for structural retrofitting while the insulation layer is theoretically interposed in between. In this case, the current study proposes a modern, unique framework capable of ensuring both energy and structural retrofitting. A promising solution in this context is Inorganic Matrix Composites (IMCs). The Fabric Reinforced Cementitous Matrix (FRCM) is one of the most used among them; or rather, a composite made of a fabric inside an inorganic matrix (open grid or mesh) (lime or cement based). Even if the thickness of the inorganic matrix (compared to that of the fabric) is important, its thermal resistance is inadequate. The novelty of this research is to test a new FRCM geopolymer method by mixing fly-ash binder (reused material) and expanded glass aggregate (recycled material). In addition to thermal conductivity tests, direct tensile tests for measuring tensile stress, ultimate strain and elastic modulus were performed. The findings were similar to those of the conventional FRCM (commercially available). The potential of the Structural and Energy Retrofitting Proposal is discussed and possible implementation examples are also mentioned.

Recent Study on Dielectric Properties of Epoxy Resin Fly Ash Composite | Chapter 9 | Recent Developments in Engineering Research Vol. 9

In high voltage applications, epoxy resin is commonly used as an insulating material. In order to improve its mechanical properties, ceramic fillers are often applied to the polymer matrix. But at the same time, the electrical properties are reduced by filler materials. So, it is obvious to detect the effect of fly ash reinforcement on the dielectric nature of the material when making the fly ash epoxy composite. Fly ash is applied to four different formulations of weight percentages in the current research work and postcuring has been performed in the atmospheric condition, regular oven and micro oven. Ceramic filler such as fly ash improves the mechanical properties of good dielectric properties. Permissibility and tan delta in the 1 Hz - 1 MHz frequency range. The fee for room Using the pulse electroacoustic (PEA) technique, acts were also observed. The dielectric power unit For various circumstances, strength and loss are compared. The composite of fly ash epoxy polymer may be Used as a strong dielectric material in the electrical and electronics markets.
