Activation method for powder from wasted oyster shell |
| abstract |
Drying and baking the shell at 600 ° C or higher for 1 hour; Pulverizing the dried and baked shell and pulverizing the pulverized product to 300 mesh or less using a centrifugal vibration mill to produce an activated powder having a specific surface area of 1000 to 1800 cm2 / g; The present invention relates to a method for activating a shell powder comprising an activated shell powder or an active shell powder alone or in combination to form a product, It has an effect that can be used for manufacturing the material. In addition, the present invention has the effect that it can be used as a good building material since cracking is prevented by enhancing the bonding force and cracks do not occur after drying shrinkage. In addition, the present invention has the effect of replacing existing building materials using inorganic limestone such as heavy coal and wonder. |
