Microsilica is A Highly Pozzolanic Material That Is Used To Enhance Mechanical And Durability Properties Of Concrete. It May Be Added Directly To Concrete As An Individual Ingredient Or In A Blend Of Portland Cement And Silica Fume. Initial Use Of Silica Fume In Concrete Was Mostly For Cement Replacement, Along With Water-reducing Admixtures (wras). Eventually, The Availability Of High- Range Water - reducing Admixtures (Hrwras, Often Referred To As Super plasticizers) Allowed New Possibilities For Use Of Silica Fume To Produce High Levels Of Performance.

We are looking forward to import micro silica 97% from worldwide suppliers or exporters. Quantity Required : 10,000 Tons Shipping Terms : FOB Kazakhstan Payment Terms : 50 % T/T on order and 50 % T/T against shipping documents Microsilica (silica fume) is a by product from silicon metal or ferro silicon industries,is an amorphous silicon dioxide sio2 which is generated as a gas in submerged electrical arc furnaces during the reduction of very pure quartz. As the molten metal is produced, a silica-based gas is emitted. This gaseous fume, as it rises, cools rapidly and forms extremely minute,amorphous, spherical particles. The microsilica is collected in a bag house, a system for filtering the hot air and gases vented from the furnace. This gas vapor is condensed in bag house collectors as very fine powder of spherical particles that average 0.1 to 0.3 microns in diameter with a surface area of 17 to 30 m2/g. Microsilica can be used in concrete and refractory materials. Microsilica ,when used in concrete, it can improve concretes properties such as compressive strength, bond strength and abrasion resistance, reduces permeability,and therefore helps in protecting reinforcing steel from corrosion. At the same time, microslica can still be used in the procustion of refractory and porcelain, to raise intensity and durability, it also can be used in paint, coating resin rubber and other high molecular as a filler material to improve the material overall performance.

Microsilica is very fine pozzolanic material.This product comprises microcopic particles collected by filters downstream from smelting process in silicon ferrosilicon alloys.

Microsilica, also known as silica fume, is an ultrafine powder with high SiO2 content and high pozzolanic activity. It is used as a property-enhancing material in many areas, such as concrete construction, refractory, chemical fertilizer. ACC has been supplying micro silica since 2005. Our densified , undensified, and white microsilica products are with minimum SiO2 contents ranging from 85% to 98%, which have been used in many famous projects around the world. ACC can also provide micro-silica powder with higher SiO2 contents and specifications according to the requirements of customers. ACC microsilica complies with ASTM C 1240 and EN13263:2005 standards and has been recognized by SGS, Exova, and other famous test authorities and ENR enterprises. The recycle, densifying and filling processes are automatically integrated in a closed environment without any mixture or impurities. We can fix clientsâ?? orders in a stable production base so as to ensure the consistency and stability of quality.
