Use of Micro Silica in Concrete - IJIRST

2016-5-3  Micro silica Micro silica, also known as Silica fume is an amorphous 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. The main field of application is as pozzolanic material for high performance concrete. The properties of fine aggregate are shown in Table 4.
