Course Overview

Reinforced concrete is a very versatile and durable building material. Reinforced concrete efficiently combines the best properties of concrete and reinforcing steel into a strong structural element. In addition, the high alkalinity of concrete helps to protect the embedded steel from corrosion. However, due to the porosity of concrete, its use in exterior environments and tendency to be exposed to deleterious chemicals, this material can easily be subjected to deterioration.

Deterioration of concrete can take the form of corrosion of the internal reinforcing or degradation of the exposed surface of the material. Cracks increase the likely hood of the deterioration of concrete in most environments. Concrete can also become deteriorated via freeze/thaw cycles, internal aggregate reactions and heat.

Visual and destructive methods of investigation should be employed when determining the cause of concrete deterioration. The results of the physical observations and material tests associated with a proper investigation should be used to establish the best methods of repair and prevention of further deterioration.

Course Objectives

The objectives of this course are for the participants to become able to: 

1. Recognise the mechanisms of degradation of concrete structures and conduct preliminary forensic assessment of deteriorated concrete structures; 

2. Learn how to conduct field monitoring and non-destructive evaluation of concrete structures; 

3. Assess alternative repair strategies for deteriorated concrete structures including repairing with composites; 

4. Evaluate stabilizing and strengthening techniques of reinforced concrete structural elements; 

5. Carry out a study on a topic related to the durability and repair of concrete structures, author a technical paper on the study and present it verbally.

Who Should Attend

The civil and structure engineers with junior and senior level or another discipline need to know deeply about the structure engineering activities and how can cooperate with them in design phase.
