Course details
Reinforced concrete is still commonly used for building and construction in Singapore and around the world. Sustainability considerations in recent years have resulted in an increased focus on the repair and refurbishment of all types of concrete structures rather than demolition and redevelopment. Furthermore, defects are now more evident in building constructed during the boom years of economic growth when buildings are erected at a very fast pace.
This series of programme will provide the participant with the technical knowledge on the causes of structural and non-structural defects in concrete, their remedies , repairs and the preventive maintenance needed to upkeep these structures.
Objective
The specific objectives of Module 1 on Corrosion of Steel in Concrete and Concrete Defects are to familiarize the participants with how corrosion of steel reinforcement occurs in concrete. Participants will also understand other types of concrete defects and how to reduce the formation of these defects.
The specific objectives of Module 2 on Structural Inspection and Repair Techniques are to familiarize the participants with the common repair and strengthening methods for concrete structures with defects. Participants will also understand the procedure for structural investigation and effects of fire on reinforced concrete structures.
