CFRP reinforced structure reinforcing steels features and application advantages
1 CFRP have excellent physical and mechanical performance, tensile strength than ordinary steel 10-15 times, the elastic modulus and closer, steel reinforced concrete reinforcement for repair.
2 acid, alkali, salt and atmospheric corrosion. Without regular maintenance of concrete structure, and the internal protection, can achieve dual purpose of strengthening repair.
3. Because of the CFRP is soft, even reinforcement in roughness object, also can guarantee 100% effective paste. Such as paste surface partial with bubbles can be easily with syringe injection of adhesives, this method will be driven away in air stickup plate is very hard to do.
4. Not have wet operation, without large-scale construction equipment and field fixed facility. CFRP can be arbitrary clipping, simple construction, short construction period.
5 pasting CFRP reinforcement can be widely used in various types of repair and the shape of the concrete structure, and the shape and structure change does not affect the exterior structure.
After paste weigh per meter squared less than 1.0kg (including powder weight), a layer of CFRP thickness is about 1.0mm, after repair does not increase weight and overall dimensions.
Applied range of CFRP
Using load increases
Change building use function
Additional concrete of the dry wall or wet wall strength
Insufficient strength of beam, plate and column
Corrosion of steel bar
Structural system change
Restrain crack growth
Basalt cloth product features
Basalt have the higher use intensity and elastic modulus, the tensile strength and elastic modulus is 4Gpa110pa respectively.
Basalt fiber has the stable chemistry performance, acid-alkali resistance can better than glass fiber.
Low heat transfer coefficient (heat transfer coefficient for 0.031 ~ 0. 038W/m.k), is the most ideal heat insulation materials.
The basalt fiber with the higher sound-absorbing coefficient, it is the coefficient for 0.9-0.99, is high-efficiency sound insulation materials.
The basalt with the higher volume specific resistance, it is the coefficient up to 1.0*1.0ohm.m.
Basalt with the higher temperature using range and good use performance of the high and low temperature. The use of basalt fiber use temperature range for -260-600, the highest temperature can achieve above 900.
Heat-resistance of basalt fiber is superior to E glass fiber of mineral wool, close to the high price of high temperature resistance quartz glass fiber. Below the 100-250 can increase the tensile strength for 30%, below the 100 working, the fracture strength can still maintain the 80% original strength.
Hygroscopicity of basalt fiber is lesser than 0.1%, below the aramid fiber, rock cotton and asbestos.
