Oyster Shell is a feed grade calcium carbonate for layers, breeders, turkeys, chicks, swine and cattle. The analyzed value of Magnesium (MgO) in C. madrasensis shell was 0.619%, which is comparatively larger than the previous study. 4,7,8) but little is known of its crystallography and mode of formation. Oyster Shell Flour is a premium Calcium source that takes longer to break down than other Calcium sources. The important aspect to consider is the materiel that you’re comparing the shell to. Further studies to be done towards the addition of up to 10% oyster shell powder to ordinary Portland cement to assess the impact on its strength and stability. 2. The remaining elements Sodium as sodium oxide at 1.119%, Magnesium as magnesium oxide at 0.619%, Sulfur as sulfur dioxide at 0.403%, Strontium as strontium oxide at 0.020% and hydrogen as moisture exist only in negligible percentages. In Crassostrea madrasensis, these elements have been identified as Calcium and Carbon (Li) have been quantified as contributing on an average 91.36% by weight of the shell in this study. Parameters like moisture, ash, calcium, magnesium, strontium and sodium were detected in the Central Institute of Fisheries Technology, By-Products Laboratory, cochin. In comparison, raw oyster shells removed almost no phosphate from water, whereas oyster shells heated to 75°C under an air atmosphere removed a moderate proportion (up-68%) of phosphates from water[13]. The experimental results demonstrate that oyster-shells can be resources of pure calcareous materials and effective in replacement of sand, indicating promising reusable construction materials. prepared mixtures of recycled polyethylene (PE) and oyster-shell powder, that was coated with ionic surfactant, to test their fire-retardant properties. will be. The oysters are found from the intertidal zone to a depth of about 4 meters. Oyster shells are a waste product from mariculture that presents a major disposal problem in coastal regions such as south east Korea. In the present study for Crassostrea madrasensis, the percentage concentration of Calcium (CaO) in the shell has been recorded at 47.49%, which is a 7.11% variation between the two species.

A chemical is: "a substance produced by or used in a chemical process." @article{Matter1969TheCO, title={The composition of fossil oyster shell proteins. In the present study, among the chemical constituents analyzed like Calcium, Carbon, Sodium, Magnesium, Sulfur, Strontium and Moisture, Calcium and Carbon were present in high concentrations while all the remaining constituents were observed at low values below 1.5%. The procedure of analysis for both Flame Photometry and ICP was based on the Official methods of analysis of AOAC International, 2005[16]. What is the chemical composition of oyster shell.
