Abstract:
The paper presents a review on the role of silica fume in concrete, based mainly on the experience of the author and that of his colleagues. Statistics on the amount of silica fume pro-duction, its composition , quality and the way it is handled and proportioned for making concrete are described briefly. Various factors such as water/cement ratio, temperature of curing, super-plasticizer, etc., that influence the physical and mechanical properties of freshandhardened concrete are also discussed. Factors that determine the economy in the use of silica fume is emphasized. A brief survey of the literature pertaining to silica fume concrete is also included.
