Description
Micro silica fume in the building materials industry and
sales
Micro-silica fume is at home and abroad in
the field of high and new technology has broad application
prospects for the fine material can be widely used in chemical
industry, metallurgical industry. For cement or concrete to improve
the performance of concrete or cement, prepared with ultra-high,
strong, wear-resistant, resistant to erosion, corrosion-resistant,
anti-penetration, antifreeze, the early strength of concrete or
special cement compound to meet the oil - Well, marine oil drilling
platform, harbor terminals, railway bridges highways, airport
runways, tunnels and urban high-rise building projects, such as the
special requirements; rubber can be used to improve the extension
of rubber, tear and tensile strength ; For ceramics and
refractories, effective products to improve the strength and
durability.
1. Micro-silica fume concrete used in
water conservancy and hydropower project, the project can improve
the ability of anti-erosion at home and abroad traditional
anti-abrasion material to make more use of polymer materials such
as epoxy mortar, anti-erosion ability of such materials is a good
one, but because of its own Linear expansion coefficient several
times in the basement of ordinary concrete, concrete basement and
adapt to the temperature is not good, in the natural climatic
conditions cracking off easily, and construction of the complex,
toxic, costly and can not promote the use of a large area. The use
of micro-silica fume concrete, abrasive impact the ability to
double about anti**8m / s velocity-class anti-erosion ability to
raise more than 3 times.
2. Micro-silica fume concrete in the
water, the project can improve the crack resistance of hydraulic
concrete cracks, has become a major issue of general concern.
Cracks in the material itself due to hydration heat of warming,
such as the incorporation of fly ash in concrete, although
lower-temperature electric heating, but the early strength is
relatively low, so that the limited amount of fly ash.
3. Micro-silica fume concrete can improve
the performance and the infiltration of anti-corrosion properties
of salt to protect the steel.
Underwater engineering due to infiltration
of chloride ions in concrete, causing rapid corrosion of reinforced
concrete delamination, short life expectancy, a serious
destructive. Underwater concrete pouring generally catheterization,
as the loss of cement so that it can not bond with the grass-roots
level, and to reduce contact with water in some of the strength.
The introduction of concrete under water in the micro-silica fume,
these problems could have significantly improved.
4. Micro-silica fume concrete road traffic
in the road repair, is extremely wear-resistant properties
