Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. The main field of application is as pozzolanic material for high performance concrete.

It is sometimes confused with fumed silica (also known as pyrogenic silica, CAS number 112945 ....etc

HIGH PERFORMANCE CONCRETE USING FUMED SILICA

INTRODUCTION

High performance concrete is a concrete having low water binder ratio. A value of 0.4 is suggested as boundary between usual concrete and high performance concrete.
It has high strength and durability. For high durability low permeability is required and to reduce permeability silica fume is used

Abstract
In 1980 a sidewalk was built at B cancour, Qu bec, with condensed silica fume concretes containing highly reactive aggregates. Eleven concrete mixes were used with cement quantities from 140 to 405 kg of cement per m3 and condensed silica fume substitutions varying from 10 to 40%. In spite of the great reactivity of the aggregates, the alkali-aggregate reaction is still under control. Microstructural studies of four particular concretes have been made after the first and third winters. No silicate gel has been observed in the two le ....etc

Abstract

This study presents an experimental study on self-compacting concrete (SCC) with two cement content. The work involves three types of mixes, the first consisted of different percentages of fly ash (FA), the second uses different percentages of silica fume (SF), and the third uses a mixture of FA and SF. After each mix preparation, nine cylinder specimens are cast and cured. Three specimens are cured in water for 28 days, three specimens are cured in water for 7 days, and three specimens are left in air for 28 days. The slump and V-fun ....etc

Silica fume is also referred to as micro silica or condensed silica fume but the term silica fume has been generally accepted. It is a by-product of manufacture of silica and ferrosilicon alloys from high purity quartz and coal in a submerged arc electric furnace. It is reported that the addition of ultra fine particle in HPC improves the strength of concrete. The optimum silica fume proportions in between 20% and 25% by weight of concrete. In it self silica fume does not have any binding properties, but it reacts with calcium hydroxide on hydr ....etc
