Silica fume shotcrete, the next big thing in construction projects

Silica fume shotcrete is well known for use in the reinforcement of existing structures, this property is attributed to the flexural strength of silica fume. Since the silica fume particles give out a high density material, silica fume shotcrete is highly resistant to chemical attacks by sulfates, nitratlar, chlorides, alkaliaggregates, and acid reactions .
