The micro silica is formed when SiO gas produced in the furnace mixes with oxygen, oxidizes to Si02, condensing into the pure spherical particles of micro silica that form the major part of the smoke or fume from the furnace. These fumes are collected and bagged called silica fume. It is also known as condensed silica fume and micro silica.

Micro Silica Sand: Micro silica also known as fume, 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 mm.

Ready-to-use bagged and powdered micro-silica (silica fume) to improve concrete properties such as strength and permeability.

Micro Silica (MS) has proven to be an excellent admixture for Portland cement concrete. Addition of Micro Silica (MS) to concrete mix usually results in significant improvement in strength, durability and permeability. Some of the improvements to the concrete properties occur because Micro Silica …

In this paper, an attempt has been made to study the effect of replacement of cement by micro silica on the flexural strength of fibrous ferrocement using GI fibers. The percentages of GI fibers were varied as 0%, 0.5%, 1.0%, 1.5%, and 2.0%. The cement was replaced by micro silica in different percentages like 5%, 10%, 15%, 20%, 25%, and 30%.

Jun 01, 2016· Results shown in Table 4 were obtained for 3 representative samples for each level of micro-silica from cement ratio in concrete coating, each level of micro-silica from cement ratio give low values of water absorption due to the decrease in the porosity and permeability of concrete specimen modes with different micro-silica contents. 2.5.
