About us
Luoyang Jihe Micro-Silica Fume Co., Ltd is professional in exploiting, producing and selling micro-silica (silica fume, http://comunevillabasilica.com/Products/20141222/59.html
). We built up our own producing and processing factories in Shanxi, Qinghai and Yunnan Province, and have 3600 tons production in one month. We provide high quality product with low price.
The acreage of the Luoyang storehouse is 5000m2, the large storehouse makes by stacking by different grades and category to be possible.
In order to ensure the stability of product quality, We built our own laboratory, every batch of silica fume must be tested before put in storage. When the order shipped, the test report of the product must be sent to the customer.
Product Description
Microsilica fume (scientific name "silica fume," Micro-silica or Silica Fume), in the smelting of ferrosilicon and industrialsilicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2).Microsilica fume average 0.1-0.15 μ m in diameter, the size of several cement average 1.0%. Surface area for the 15-27 m 2 / g, with strong surface activity.
How Silica Fume Works in Concrete:
High properties of silicafume which improves characteristics of Concrete:
1. Compression strength.
2. Adhesion strength.
3. Wear resistance.
4. Freeze resistance.
5. Chemical durability.
6. Considerably reduces permeability.
7. Resistance to Sulfur and Alkali attacks.
8. Increased Insulation Properties.
Where Silica Fume Should Be Used
It is used best for Insulation properties in Commercial and Residential Infrastructures, such as: Damns, Bridges, Power projects, Transmission Projects, Railways, Canals, Flyovers & Bridges, Highways and Airports, Industrial floorings, Used as admixture for waterproofing, etc.
It is suggested that even multistory buildings and high end complex’s including heavy infrastructures can use silica fume
Advantages of silica fume in concrete:
Very low permeability to chloride and water intrusion.
Extremely high electrical resistivity( 20 to 100 times greater than ordinary Concrete).
Increased abrasion resistance on decks, floors, highways and marine structures, Superior resistance to chemical attack from chlorides nitrates and sulphates. Compressive strengths up to 20000 psi ( 140Mpa ). High flexural strengths(14 Mpa @ 28 days) for airport pavements.
High early strengths for fast track construction projects and precast applications, Highway bridges, parking decks, marine structures and bridge deck overlays are subject to constant deterioration caused by rebar corrosion current, abrasion, chemical attack.
Silica fume will protect concrete against deicing salts, seawater, road traffic and freeze/thaw cycles. Rebar corrosion activity and concrete deterioration are virtually eliminated, which minimizes maintenance expenses.
