Repairing Reinforced Concrete: Diagnosis, Principles and Materials

This seminar follows a repair from first inspection to final testing: how reinforced concrete deteriorates, how to investigate it, how to use the EN 1504-9 principles to choose a strategy, how to select compatible repair mortars, and how to specify preparation, application, curing and inspection.

Learning objectives

1. Diagnose the causes of concrete deterioration, including carbonation, chloride attack, cracking and chemical attack, from site evidence and testing
2. Apply the EN 1504-9 principles and methods to choose a repair and protection strategy
3. Select repair mortars by structural class (R1 to R4) and compatibility with the parent concrete
4. Specify surface preparation, reinforcement treatment, application, curing and inspection for repairs that last
