摘要
The present invention relates to a mortar composition for embedding a pile using an oyster shell, a method for manufacturing the same, and a method for embedding a pile using an oyster shell. A method of manufacturing a mortar composition for embedding a pile using an oyster shell of the present invention includes a first pulverizing step of crushing an oyster shell (original closed shell) discharged from Park Shinjang; A first sorting step of passing the pulverized product through the first pulverization step through a screen to filter out small organic matter and shell powder having a small particle size to obtain shell pieces having a large particle size; After preparing the inorganic releasing material, the shell pieces are mixed and put into a cylindrical drum with crushing protrusions formed on the inner circumferential surface, and then the drum is rotated for a certain period of time. A foreign matter peeling step of peeling off the attached salt and organic matter; A second sorting step of passing the contents of the cylindrical drum through a sorting net to filter out the peeling material containing salt and organic matter, and to selectively obtain only shell pieces; A second pulverization step of pulverizing the secondly selected shell pieces to obtain fine powder having a particle size of 0.001 to 2 mm; And a mortar raw material mixing step of preparing a mortar composition by mixing cement or solidified material in a residual amount with 10 to 40% by weight of the shell fine powder. According to the present invention, the pretreatment of oyster shells generated in a large amount is made easier and more convenient, and by minimizing the use of water, it is possible to reduce ancillary costs required for drying without going through the wastewater treatment process of washing water. By utilizing shell powder containing foreign substances for compost production, it is possible to maximize the recycling rate of oyster shells, and by pre-treating oyster shells in a non-fired manner, fuel costs are reduced, and the process proceeds without carbon dioxide generation, providing an eco-friendly treatment method. In addition, organic matter and salt can be more easily removed by allowing the peeling process to proceed after the oyster shell is primarily pulverized and selected.
