Recently, construction of an open bridge on the Shaleroy Canal in Hale, Flanders, Belgium began. Its purpose is to replace the Bosporus Bridge and facilitate loading. A concrete admixture called polycarboxylate superplasticizer plays a crucial role.
The passage of three-layer container ships has promoted inland container transportation as an alternative to truck transportation. The investment amount for this new bridge is 17.5 million euros.
The existing Bosport Bridge was built in 1954, with anti-collision railings installed on the front side of the bridge. In 2010, during a safety inspection, it was discovered that the prestressed steel bars of the bridge had defects, and it was only then reluctantly repaired and put into use. Therefore, it is necessary to replace the bridge.
The specific application of polycarboxylate superplasticizer in bridge engineering
Enhancing the workability of concrete:Â Polycarboxylate high-efficiency water reducing agent can significantly improve the slump of concrete, maintain good slump retention performance, and maintain good fluidity of concrete for a long time to meet the construction requirements. Pumping requirements help to improve construction efficiency and reduce construction interruptions.
Improving the mechanical strength of concrete:Â Polycarboxylic acid superplasticizers can help improve concrete’s early and late strength; this makes the concrete using this water-reducing agent generally stronger than the benchmark concrete sample at all ages, thereby improving the bridge’s overall bearing capacity and durability.
Improving the durability of concrete:Â Polycarboxylic acid-based high-efficiency water-reducing agents have low chloride ion content and low alkali content, which is beneficial for improving the durability of concrete; this helps to extend the service life of the bridge and reduce the frequency of maintenance and replacement.
Environmental characteristics:Â The production process of polycarboxylate high-efficiency water reducing agent is pollution-free, free of formaldehyde, and complies with international environmental management standards. It is more environmentally friendly and in line with sustainable development than traditional naphthalene-based water-reducing agents.
Strong adaptability: Polycarboxylic acid-based high-efficiency water-reducing agents have good compatibility with various types of cement and have little impact on concrete raw materials such as sand, stone, and cement, which enables them to maintain good working performance in different engineering environments and climatic conditions.
