| titleOfInvention | Salinity blocking material using waste concrete and its manufacturing method |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a salt barrier material for preventing salt damage, wherein the salt barrier material prevents the soil of the landfill from being salted from salt by using the drainage function of the waste concrete particles, capillary blockage, and salt absorption function. To provide.n n n The present invention is adopted as a salinity blocking material using waste concrete, which is an industrial waste, and due to the characteristics of the waste concrete with high porosity, the salinity is removed from the underground, and the salinity caused by rainfall or water supply can be efficiently removed. There are advantages to it. The salt barrier material of the present invention can neutralize waste concrete as a means for lowering the pH of waste concrete. When sulfur or sulfuric acid is used as the neutralizing agent, the salt component is raised through a chemical reaction that reacts with Na + to form sodium sulfate. It has the effect of suppressing. In addition, the present invention adopts the industrial by-product gypsum as a coating material of the waste concrete, it is effective to increase the salt blocking ability of the waste concrete through the chemical reaction of adsorption and removal of salt using calcium and sulfur contained in the gypsum have.n n n n Waste concrete, salt block, gypsum, capillary phenomenon |
