SILICA FUMECONCRETE

INTRODUCTION

Silica fume is also referred to as micro silica or condensed silica fume but the term silica fume has been generally accepted
The addition of ultra fine particles in concrete improves strength of concrete
The optimum proportion of silica fume is found in between 20% and 25% by weight of concrete
Silica Fume when react with calcium hydroxide on hydration of cement produces calcium siicate hydrate which has good binding properties.

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
