Title: Innovations of Jin-Man Kim
Introduction
Jin-Man Kim is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of materials science, particularly in the development of hydraulic binders. With a total of 5 patents to his name, his work focuses on enhancing the properties and applications of slag-based materials.
Latest Patents
One of Jin-Man Kim's latest patents is a hydraulic binder composition using rapidly-cooled steelmaking reduced slag powder, along with a method of preparing the same. This invention involves obtaining rapidly-cooled steelmaking reduced slag (RC-LFS) powder by spraying and scattering gas at high pressure onto electric furnace smelting reduction slag. The process ensures that the initial high hydration heat reaction and setting are delayed, thus improving workability. The addition of a retardant and gypsum activates the generation of needle-shaped ettringite, enhancing both initial and long-term strength. This innovative binder can serve as a substitute for ordinary Portland cement.
Another significant patent is the ultra-rapid hardening hydraulic binder using reduced slag powder, which includes a method of preparation. The reduced slag powder is created by rapidly cooling molten electric arc furnace reduced slag to room temperature. This process prevents the presence of free-calcium oxide by dispersing the molten slag into the air using high-pressure gas.
