Extra rapid curing mortar composition containing rapid cooled reduced steelmaking slag powder and electric arc furnace dust

摘要

The present invention relates to an ultra-fast mortar composition using rapid-cooled steelmaking reduced slag powder and electric furnace steelmaking dust, and more particularly, high-pressure air is sprayed onto the molten reduction slag with an electric furnace, which is an industrial by-product generated during iron smelting at a steel mill. The rapid cooling steelmaking including the rapid-cooled steelmaking reduced slag powder and the high-heat dust generated in the melting process of the electric furnace are collected by the dust collector while rapidly cooling the molten reduced slag while scattering it into fine droplets, and the electric furnace steel making dust. It relates to a mortar composition of ultrafast hardness using reduced slag powder and electric furnace steelmaking dust.
