What is Blast Furnace Slag? - Definition from
2020-12-14 Blast furnace slag is a non-metallic residue usually obtained from steel plants or from the reduction of ores in a blast furnace. It is used as a mud cake modifier for the cementing of oil and gas wells.. It has been found that using a slag mix for cementing is beneficial economically and technically as well as better for the environment than Portland cement.
