What are the main admixtures to use to mitgate the negative effect of clay minerals on UCS?
Best insight from top research papers
To mitigate the negative effect of clay minerals on Unconfined Compressive Strength (UCS), lime and nanosilica can be used as admixtures. The addition of lime and nanosilica to gas oil contaminated clay increased the UCS of the soil . Lime, when added to soil, showed a considerable increase in strength characteristics at an optimum lime content of 5% . Nanosilica, when added in a mixture with lime, was found to be more efficient in improving the UCS of the contaminated soil . By adding 3% of the nanosilica-lime mixture and increasing curing time, significant UCS gains were observed . Therefore, lime and nanosilica can be used as effective admixtures to mitigate the negative effect of clay minerals on UCS.

How clays interact with essential oils?5 answersClays interact with essential oils through various mechanisms such as adsorption, intercalation, and nanoencapsulation. Clay minerals like montmorillonite can act as carriers for essential oils, enhancing their stability and bioavailability in nanocomposites. The adsorption of essential oils onto clay surfaces, particularly smectites, can involve exchange of ions and even covalent bonding with organic compounds. Studies have shown that purified clay can effectively adsorb essential oils like Caraway oil, leading to the formation of bio-hybrids with enhanced antibacterial and antifungal properties. Additionally, the type of soil, such as clay or sand, can influence the composition and yield of essential oils from plants like grapefruit and shaddock, highlighting the importance of soil selection for optimal essential oil production.
What are the environmental impacts of using clay mineral compounds as supplements in animal feed and manure management systems?5 answersClay mineral compounds used in animal feed and manure management systems have various environmental impacts. They can enhance the removal of veterinary antibiotics from anaerobic digestion processes, reducing their negative effects on methane production and improving overall process efficiency. However, clays may interfere with gastrointestinal metabolism, affect nutrient absorption, and potentially elicit inflammatory responses in animals. Additionally, clay minerals and zeolites show promise in soil and water remediation by sequestering contaminants like heavy metals and organic pollutants, thus improving soil quality and reducing environmental pollution. In ruminant diets, the inclusion of clays like zeolite can stabilize rumen pH and ammonia concentration, especially in high-concentrate diets, impacting microbial fermentation and overall digestive processes. Overall, the use of clay mineral compounds in animal systems can have both positive and negative environmental implications, highlighting the need for further research to fully understand their effects.
What are the potential benefits and drawbacks of using edible clay as a food source for research purposes?5 answersEdible clay, traditionally used for various purposes, presents both benefits and drawbacks. Research indicates that clay inclusion in cow diets reduces radionuclide content in milk, showcasing its potential benefit as a sorbent. However, studies on edible clays reveal the presence of heavy metals and contaminants, posing toxicity risks at certain doses. Conversely, an analysis of edible clay samples from Zambia suggests that they do not contain harmful concentrations of heavy metals, indicating safety for consumption. Additionally, a study on rats consuming an edible clay suspension shows adverse effects on serum lipid profiles and atherogenic indices, highlighting potential health risks associated with its consumption. Therefore, while edible clay may offer benefits like radionuclide reduction, its potential drawbacks include heavy metal presence and adverse effects on health parameters.
What are the adsorption applications of clay minerals?4 answersClay minerals have various adsorption applications. They can be used as green and affordable adsorbents for environmental remediation, particularly in the removal of emerging pollutants. Phyllosilicates, a type of clay mineral, have a high adsorption capacity due to their nanometric interlayer space, making them suitable for environmental applications such as retaining organic residues in soils and serving as nanocarriers for controlled release of pharmaceutical drugs. Clay minerals, including amino-functionalized ones, can be tailored to design functional materials for adsorption of water contaminants such as organic pollutants, drugs, surfactants, pesticides, anions, heavy metals, and even gases like CO2. Montmorillonite (MMT), a type of clay mineral, is particularly effective for wastewater remediation due to its high porosity, mechanical strength, cation exchange capacity, and swelling properties. Surface modification and functionalization of MMT can further enhance its adsorptive performance and enable photocatalytic activity for the elimination of various contaminants. Thermal and chemical treatment can also influence the adsorption properties of clay minerals, with heat treatment increasing energy centers and cation exchange capacity, and sintering causing a loss of adsorption properties.
What are some specific examples of how clay has been used in the pharmaceutical industry?5 answersClay minerals have been used in the pharmaceutical industry for various purposes. They have been utilized as carriers for active ingredients, controlling their release and increasing their bioavailability. Clay minerals, such as halloysite and sepiolite, have been studied as drug delivery systems, enhancing the stability, controlled release, bioavailability, and adsorption properties of drugs. Clay minerals have also been used in the synthesis of new and biocolored hybrids, which can be used as biocosmetic products without negative side effects on human health or the environment. In addition, clay minerals have been explored as excipients and active ingredients in various dosage forms, including suspensions, emulsions, ointments, gels, and tablets. The unique structure of clay minerals allows them to absorb materials onto their layered sheets, making them versatile in drug delivery applications.
What are the negative impacts of CCS on soil?5 answersCCS can have negative impacts on soil. Increased soil CO2 concentrations resulting from CCS leakage can decrease the crude fat content of sunflowers, reducing their commercial value. However, the elevated CO2 in soil can also improve the quality of sunflower oil by increasing the crude protein and linoleic acid contents. Soil particle size distribution and heavy metal concentrations do not show significant impacts with elevated CO2 concentration. Soil type and structure may play a minor role in mitigating or amplifying plant stress in response to CO2 leakage from CCS infrastructure. Switchgrass cultivation under CCS does not show short-term changes in soil organic carbon, but after 10 years, soil organic carbon is higher compared to fallowed soil. The design and operation of onshore pipelines for CCS should consider the heat transfer and thermal resistance in buried pipelines to prevent heat loss from the dense phase CO2 fluid.
