Latest Patents

Sun-Mi Choi holds a patent for a hydraulic binder composition that utilizes rapidly-cooled steelmaking reduced slag powder. This invention involves a method of preparing the binder, which is derived from electric furnace smelting reduction slag. The process includes spraying gas at high pressure onto the slag, leading to rapid cooling and pulverization. This innovative approach delays the initial hydration heat reaction and setting time, enhancing workability. The addition of a retardant and gypsum activates the generation of needle-shaped ettringite, which contributes to both initial and long-term strength. This hydraulic binder can serve as a substitute for ordinary Portland cement.
