METHOD OF PRODUCING FUNCTIONAL CEMENT MORTAR AND THE FUNCTIONAL CEMENT MORTAR PRODUCED BY THE METHOD

摘要

A preparation method of functional cement mortar is provided to adsorb volatile organic compounds produced by cement and emit anions and far-infrared rays, thereby increasing the activity of a human body in an environment-friendly home environment. A preparation method of functional cement mortar includes the steps of: mixing cement, sand and water in an agitator to obtain cement mortar; and adding 10-100wt% of nanopowder anion generating granulated blast-furnace slag with respect to the cement weight. The nanopowder anion generating granulated blast-furnace slag is prepared by: pulverizing granulated blast-furnace slag at room temperature and at low speed; depositing the pulverized powder into water to which weak current is applied; transferring the deposited slag to an ultrasonic zone; applying an ultrasonic wave to the slag for a preset amount of time; gradually drying the slag in an Al ceramic kiln under oxygen and radon ions; and mixing the dry slag with baked tourmaline. Further, the granulated blast-furnace slag is pulverized into 20 - 325 mesh.
