What is Blast Furnace Slag? - Definition from Trenchlesspedia

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 ...

Water quenching blast furnace slag (WQBFS) is widely produced in the blast furnace iron making process. It is mainly composed of CaO, MgO, Al 2 O 3, and SiO 2 with low contents of other metal elements such as Fe, Mn, Ti, K and Na. In this study, WQBFS was treated with grinding, hydrochloric acid acidification, filtration, filtrate extraction by alkali liquor and a hydration reaction.

What is Blast Furnace Slag? - Definition from Trenchlesspedia

Trenchlesspedia Explains Blast Furnace Slag. Blast furnace slag is durable and has long-term compressive strength due to its pozzolanic and hydraulic characteristics when finely ground. Since zonal isolation in the annular space between the casing and the borehole is very important, it has led to the development of a method to obtain improved zonal isolation using drilling …
