Silica Fume (Microsilica) - Advanced Cement Technologies for Concrete Repair Formulations - Industry Trends and Survey by 2024
Silica fume is a byproduct released in electric arc furnaces during the production of ferrosilicon alloys or silicon metal. Chemically, it is very fine silicon dioxide (SiO2). The individual particles of silica fume are very small, about 1/100th of the size of an average cement particle. Owing to its increased surface area, high SiO2 content, and the presence of fine particles, silica fume is a highly pozzolanic material that is used to improve the durability and mechanical properties of concrete....
