As the world's most advanced building materials.，UHPC（Ultra high performance concrete）It is considered to be the most effective way to solve the pain point problem of steel bridge at present.，However, due to the poor adaptability of the existing construction technology, equipment and materials at home and abroad,，Can not meet the low-carbon environmental protection construction of buildings、High requirements for intelligent construction and industrial production technology and equipment，It has become a difficult problem for all bridge builders.。

In the near future，Lianshiwan Bridge of Zhongshan West Ring Expressway, constructed by Poly ChangdaUHPCCompletion of Ultra-high Performance Concrete Steel Deck Pavement，Formally enter the stage of asphalt pavement construction，This innovation is the first in China.，Not only Solve “Stuck in the neck” Problem ，Green and environmental protection，But also greatly save that cost of personnel and machinery.，Improve work efficiency，Achieve a breakthrough in flatness at 3 mm level，Helps solve the problem of easy damage of steel bridge deck pavement。
It is worth mentioning that，Applied to bridge deck pavementUHPCYesJointly developed by Nanfang Road Machinery and Poly ChangdaUHPCStirring production with special equipment，The ultra-high performance concrete produced can bring lighter weight.，Lower carbon emissions and longer service life，At present, Poly Changda and Nanfang Road Machinery are working together on the promotion and application of this technology.，It has won the recognition of the industry and the owners.。

△ UHPCThe special mixing equipment is applied to Poly Changda.
This oneUHPCThe special mixing equipment is jointly developed by Nanfang Road Machinery and Poly Changda.，Relevant technical indicators are designed, manufactured and coordinated in accordance with the concepts and methods of Poly Changda Company.，At present, it has been applied for patent and applied in practice.，Help Poly grow up to beUHPCApplication industry benchmark。The equipment adopts a specially designed vertical shaft planetary mixer.，And that stir uniformity is good、High efficiency、No dead angle，Concrete and fiber can achieve better dispersion effect.，It can not only shorten the construction period, but also create greater economic benefits.。Modular design is adopted for the whole equipment，Convenient installation and quick relocation with the project。Nanfang Road Machinery can be customized according to the needs of construction units.，Poly Changda No.4 Company uses the dry powder station of Nanfang Road Machine to premix first.，Then use the planetary host module station of Nanfang Road Machine for wet mixing on site.。At the site of use，A mixture of premixed flour and other materials.，Whether it's in a bag or a barrel.，Nanfang Road Machine has corresponding adding solutions.，Just in the blender.，Add water and admixture according to the required proportion and stir evenly.，Ready to use and pour，At presentUHPCIt has become a powerful bridge.、Indispensable materials for engineering construction。

Industry trends：
Ultra high performance concrete is different from traditional high strength concrete and steel fiber reinforced concrete.，Not in the traditional sense.“High performance concrete”High reinforcement，It has ultra-high strength.、Features of ultra-high toughness and ultra-high durability，Through modern admixture technology，Rinding quartz sand、Cement、Silica fume and other ultrafine particles，Press“Closest packing” Principle ，And adding a certain amount of superfine steel fiber，Achieve ultra-high strength、Cement-based material with ultra-high toughn。
The application of ultra-high performance concrete has started in China.，Large scale of capital construction in China，Part of the project is located in harsh environment.，There are many engineering problems.，Demand is diverse，Large span bridges in China、Large and deep underground structure、There is still much room for the development of high-rise and super high-rise structures.，UHPCThe demand will be greater and greater.。
Materials are required for the realization of ultra-high performance concrete structures、Close coordination between structure and production or construction，As long as high quality materials are used.、Reasonable structure or structural system and professional construction，The quality of the project can be guaranteed.，So that the application of ultra-high performance concrete can develop normally.。

△Real scene of engineering application
As an ultra-high performance concrete，UHPCIt has excellent wear resistance and explosion resistance.，Very suitable for long-span bridges、Environments such as blast-resistant structures and thin-walled structures，Engineering materials with the best durability。If you want to consultUHPCProblems related to ultra-high performance concrete，Welcome to press for a long timeNanfang Road Machine Public Number，We have professional technical engineers to connect with you.！Also welcome friends from the industry to visit Nanfang Road Machine.、Guidance and business negotiation。
