Examples of 'silica fume' in a sentence
Meaning of "silica fume"
Silica fume is a highly reactive, fine-grained byproduct of the production of silicon metal or ferrosilicon. It consists of amorphous silicon dioxide particles and is typically collected from the exhaust gases of industrial furnaces. Silica fume is often used as a supplementary cementitious material in concrete to enhance its strength, durability, and resistance to chemical attack
