 Refractory material

Refractory material can be defined as non-metallic material that can tolerate severe or destructive service conditions at high temperatures. they have to suffer

Iron blast furnace slag

The residue resulting from the interaction of slag is
Impurities of molten limestone and iron. It contains oxides of calcium, silicon, aluminum, and magnesium, small amounts of iron oxide, and sulfur. can be slag concrete blocks, road materials, insulating roofing materials, and soil conditioners.
