Water-soluble Liquid Phase Produced Nano Silica Powder used for Concret
Nano silica powder can be used
to improve the performance of cement or concrete, formulated with ultra-high,
high high wear resistance, erosion, corrosion, anti-infiltration, antifreeze,
the early strength of special concrete or composite cement, to accommodate the
oil well cementing, ocean oil drilling platform specific requirements, port
terminals, railway bridges highways, airport runways, tunnels and urban
high-rise buildings and other projects;
For the rubber to improve the rubber elongation,
tear resistance and tensile strength; for refractory and ceramic products,
improve product strength and durability.
1. Nano silica powder used in water
conservancy and hydropower projects can improve the ability of anti-erosion
projects, the use of micro-silica fume concrete, about double impact to
abrasion, anti48m/ s
velocity level of anti-erosion capacity increased more than 3 times .
2. Nano silica powder used in
hydraulic engineering, performance engineering can improve the crack.
3. Nano silica powder can improve the
anti-permeability and salt corrosion performance, protect the steel. Underwater
engineering due to chloride ions into the concrete, causing rapid corrosion of
steel, concrete delamination, life is short, severely damaging. Underwater
concrete pouring commonly used catheter, due grout loss, it is not well with
the primary bonding, and reduce the intensity of the contact portion of the
water. After the incorporation of silica fume concrete under water, these problems
could have significantly improved.
4. The nano silica powder used in
highway pavement repair traffic, with strong wear characteristics with ordinary
concrete pouring road, need 28 days to normal traffic, general early strength
concrete have three days before the opening of the concrete road pavement
damage It is inevitable. By conventional methods to repair, often causing
traffic disruption, leading to serious economic losses. The use of micro-silica
fume concrete with early strength and wear characteristics, the actual use of
the results are quite satisfactory. Airport runways requires more than 80MPa
concrete and wear resistance, silica fume can play a very good effect.
