Setting Properties of High Aluminate Composite According to Various Temperature and Components

Among all the slags, ladle furnace slag (LFS) is reducing slag generated from electric arc furnace. After cooled rapidly by high-pressured air (atomizing technology), LFS has more amorphous phase than slow cooled slag. Therefore, it shows higher reactivity than another recycling slag. This material also is named by rapid cooling LFS (RC-LFS). Pulverized RC-LFS should be fully understood. This paper deal with the present some basic experimental properties and discussions about the setting time of pulverized RC-LFS with different gypsum under the various temperatures. According to the experimental results, the pulverized RC-LFS with gypsum can hydrate in a low-temperature environment, even though the initial and final setting time are delayed.
