Recently, GUARDEX SK series nano-silicon ion immersion modifier products independently developed and developed with national invention patent were successfully applied in Tuhehe Bridge in Dezhou section of Jingtai Expressway invested and constructed by Shandong Expressway Group, building the anti-collision column of the bridge with the same life of the structure.

Tuhehe Bridge is a key node project of Dezhou-Qi section of Beijing-Taiwan Expressway, with a total length of 997 meters, a 26-span bridge, a maximum span of 130 meters, a single bridge width of 20.5 meters, and the longest pile foundation length of 110 meters. The main bridge adopts a single box of two-chamber corrugated steel web variable section prestressed concrete continuous beam structure.

Bridge engineering common structure for reinforced concrete structure, and the concrete itself is porous, affected by material ratio, pouring vibration, maintenance, and other factors, easy to fine pores, cracks and honeycomb inside and surface, insufficient strength, and exposed to the outdoor, long bear from various complex erosion factors (such as acid, carbon dioxide, water, etc.) erosion, easy to appear leakage and corrosion problems.

Concrete corrosion problems, more common concrete carbonization, acid and alkali corrosion, chloride ion erosion, alkali aggregate reaction, freezing and thaw damage and steel bar corrosion; and these will cause adverse effects on the safety of the concrete building, the resulting later maintenance cost is also a great cost.

Therefore, it is very important to do a good job in concrete buildings, especially in Bridges.

For the concrete bridge that has been built and put into use, spraying GUARDEX SK series nano-silicon ion immersion modifying agent can give full play to the effect of improving the compaction of concrete structure, and then improve the comprehensive performance of waterproof concrete structure, anti-corrosion and salt resistance.

SK series of nano silicon ion immersion in the nano size "silicon ion" in reaction control technology, depth of penetration enhancement technology and crystallization promotion technology under multiple action, deep penetration, full reaction, generate sufficient and concrete for the same material crystallization, the crystallization is a very stable chemical structure form, it is difficult to react with any chemicals, can permanently prevent corrosive media (acid, etc.) corrosion, protect the concrete structure and internal steel bar from corrosion.

SK series nano silicon ion immersion modifying agent construction is convenient, just spraying, construction efficiency is high, even a large concrete bridge engineering, also can be quickly construction, save the construction period, and the same life of the concrete structure anticorrosion protection, later without maintenance, save maintenance costs.

GUARDEX Shandong Company ——GUARDEX (Shandong) New Material Co., Ltd. cooperated closely with Shandong Expressway Group to successfully apply SK series nano-silicon ion immersion modifying agent products in Beijing-Taiwan Expressway Tuhehe Bridge, greatly improving the anti-corrosion resistance and salt resistance, waterproof resistance, carbon resistance and other comprehensive durability of concrete anti-collision column.

Up to now, GUARDEX Shandong Company has successfully applied GUARDEX new materials in the Zibo section of Shandong Expressway, Beijing-Xiong Expressway, Yansui Expressway, Pingzan Expressway and other engineering projects, providing waterproof and anti-corrosion protection and repair services for the concrete structure of the expressway, comprehensive concrete protection, and extending the life cycle of the building.
