Some properties of concrete using microsilica
What is microsilica or silica fume? Microsilica (silica fume) results from the reduction of quartz (SiO2) by carbon in the electric arc furnace. Part of the only partially reduced quartz evaporates as SiO and is re-oxidized to SiO2, when it comes in contact with oxygen in a cooler part of the furnace.
An Introduction to Silica Fume in Concrete Industry
INTRODUCTION Nowadays Silica Fume is widely used for producing high durable concrete for structures particularly exposed to aggressive environments, such as marine structures.
