Description
This presentation from Weber explores advanced concrete repair and protection solutions, emphasising sustainability, structural durability, and the importance of proper assessment and material selection for effective long-term infrastructure maintenance.
Key Points:
- Concrete Damage, Corrosion, and Repair Fundamentals
The presentation underscores how cracks, carbonisation, and chloride contamination lead to steel corrosion in reinforced concrete. Effective repair begins with thorough assessment, including identifying contamination depth and structural integrity using standards like BSI 1504. - Repair Mortars, Systems, and Surface Preparation
Mortars are categorised from R1 to R4 based on strength and application. Proper surface prep, such as dampening, cleaning, and square-cutting, is essential for long-term bond strength and preventing shrinkage. Weber’s innovative products, including flowable concrete and dual-use mortars, streamline repair processes while improving durability. - Sustainable Protection and Advanced Systems
Protective coatings, cathodic protection systems (e.g., zinc tablets), and water repellents play a critical role in preserving concrete infrastructure. Fast-setting, spray-applied concretes are ideal for marine and tidal environments, extending structural life by up to 25 years.
Learning Objectives:
- Understand the chemical and physical causes of concrete degradation and how to diagnose them effectively.
- Learn to select appropriate repair mortars and preparation methods based on the environmental exposure and structural requirements.
- Discover innovative protective systems, including cathodic protection and coating technologies, for extending the service life of concrete structures.
