What are the Clinical studies and research supporting the efficacy of eggshell powder supplementation?4 answersClinical studies have shown promising results regarding the efficacy of eggshell powder supplementation in various health conditions. Research on osteoarthritis in dogs demonstrated that supplementation with eggshell membrane improved joint functionality and reduced pain. In a study on muscle recovery from exercise-induced damage in men, Greenshell™ mussel powder, which contains eggshell components, expedited muscle function recovery and reduced soreness. Furthermore, a study on inflammatory bowel disease in mice revealed that dietary eggshell membrane improved survival rates, gut microbiota diversity, and reduced inflammation, suggesting its potential as a beneficial intervention for IBD. Additionally, a clinical trial on osteoarthritis in humans indicated that eggshell membrane supplementation reduced pain perception, improved knee joint strength, and mobility, highlighting its potential to alleviate joint symptoms. These studies collectively support the efficacy of eggshell powder supplementation in various health conditions.
What is the Chemical composition of eggshells?5 answersThe chemical composition of eggshells typically includes calcium carbonate, magnesium carbonate, calcium phosphate, and organic matter. Specifically, the composition of chicken eggshells consists of calcium carbonate (94%), magnesium carbonate (1%), calcium phosphate (1%), and organic elements (4%). Additionally, eggshells are rich in calcium, magnesium, sodium, and potassium. The presence of these components makes eggshells a potential source of nutrients and a suitable material for various applications, such as soil improvement, organic-mineral fertilizers, and even as a natural filler in food waste products. Furthermore, eggshells have been explored for their adsorption capabilities, particularly in removing heavy metals and dyes from aqueous solutions.
How can eggshell be used as an additive in concrete?4 answersEggshell can be used as an additive in concrete to improve its properties and promote sustainability. The addition of eggshell powder to the cement system can enhance the mechanical properties and durability effects of the concrete. Eggshell powder has high amounts of calcium, making it a suitable partial replacement for cement in construction materials. Studies have shown that a 10-15% replacement of cement with eggshell powder can result in comparable strength development to control concrete. The use of eggshell powder in concrete can also improve its transport qualities. Furthermore, eggshell powder can be used as a stabilizer for soil and brick, improving their mechanical properties. The optimal dosage of eggshell powder for concrete modification is around 10%. Overall, the utilization of eggshell powder in concrete offers a cost-effective and sustainable solution for the construction industry.
What is the local literature about eggshell?4 answersThe local literature about eggshell includes studies on its potential as a value-added product for biomedical and industrial applications, such as eggshell membrane separation methods. There is also research on the structure and function of eggshells, enabled by advances in technology. Additionally, there is exploration of using eggshell biowaste from the cosmetic and pharmaceutical industry as a precursor for energy storage, specifically as an electrode material for supercapacitors. However, there is no specific mention of local literature about eggshell in the context of brown eggs or shell pigmentation.
What are the benefits of using eggshells as a fertilizer?5 answersEggshells have several benefits when used as a fertilizer. They are a rich source of calcium, which is essential for plant growth and development. Eggshells can also be used as an adsorbent to transfer adsorbed phosphorus (P) from water into the soil, addressing the issue of P deficiency in soil. The adsorption capacity of eggshells can be improved by calcining them at high temperatures, resulting in increased P adsorption. Eggshell-based fertilizers have been found to be compatible with commercial fertilizers and can be used as an alternative in home-gardening, reducing food waste and the cost of using commercial fertilizers. Additionally, eggshells can be used in the production of liquid organic fertilizer, as they contain various ions such as nitrogen, phosphorus, potassium, magnesium, and calcium, which are beneficial for plant growth.
How eggshell can be replacement to traditional bricks. foreign study?5 answersEggshell can be used as a replacement for traditional bricks in construction. Several studies have investigated the use of eggshell waste as a raw material in soil-cement bricks, showing that it can be used as a partial replacement for Portland cement, resulting in bricks with excellent technical properties. Eggshell can also be added to earthenware clay compounds to make fire clay bricks, improving their physical-mechanical-thermal properties and making them suitable for construction and thermal insulation. Additionally, eggshell powder can be used as a replacement for cement in concrete, with experimental results showing that it does not significantly affect the compressive strength of the concrete. However, it should be noted that using eggshell as a partial replacement for sand in cement mortar can lead to a decrease in compressive strength. Overall, these foreign studies demonstrate the potential of eggshell as a low-cost and sustainable alternative material for traditional bricks in construction.
