Capacity expansion and reconstruction of the Belgian Open Bridge

Recently, construction began on an opening bridge on the Charleroi Canal in Halle, in the Flanders region of Belgium. It is intended to replace the Bospoort Bridge and facilitate loading. A concrete additives called polycarboxylate superplasticizer played a vital role.

Belgian Open Bridge 

The passage of triple-decker container ships promotes inland container transport as an alternative to truck transport. The new bridge has an investment of 17.5 million euros.

The existing Bossport Bridge was built in 1954, and anti-collision railings were installed on the front side of the bridge. In 2010, during a safety inspection, it was discovered that the bridge's prestressed steel bars were defective, and then they were repaired and used reluctantly. Now, it is imperative to replace the bridge.

The specific application of polycarboxylate superplasticizer in bridge construction

Enhance the working performance of concrete: Polycarboxylate, a high-efficiency water-reducing agent, can significantly increase the slump of concrete, maintain good slump retention performance, and maintain good fluidity of concrete for a long time to meet the requirements during construction. Pumping requirements. This helps improve construction efficiency and reduce construction interruptions.

Improve the mechanical strength of concrete: Polycarboxylate superplasticizer helps improve the early and late strength of concrete. This makes the concrete using this water-reducing agent generally more substantial than the benchmark concrete specimens at all ages, thereby improving the overall load-bearing capacity and durability of the bridge.

Improve the durability of concrete: The polycarboxylate superplasticizer has low chloride ion content and low alkali content, which is beneficial for improving the durability of concrete. This helps extend the life of the bridge and decreases the frequency of repairs and replacements.

Environmental protection characteristics: The production process of polycarboxylic acid superplasticizer is pollution-free, does not contain formaldehyde, and complies with international standards for environmental protection management. Compared with traditional naphthalene-based water-reducing agents, it is more environmentally friendly and conforms to the concept of sustainable development.

Strong adaptability: Polycarboxylate superplasticizer has good compatibility with various types of cement and has little impact on concrete raw materials such as sand, stone, cement, etc. This enables it to maintain good working performance under different engineering environments and climate conditions.
