Advanced Materials for Construction and Repair of Concrete

Introduction

Concrete is used throughout the world for a wide range of applications. In order to improve the properties of concrete, recent advances in material science introduce new materials or admixtures to be added to or replace conventional concrete materials. Such materials could be used in new concrete construction and/or in repairing new or existing structures. These materials could cause more harm than the benefit or at least be ineffective if not properly used.

This five-day course will introduce newly developed concrete materials as well as the repair materials utilized in most repair works in concrete structures either for those needed during construction or for the rehabilitation of existing structures. The course will also cover test methods and technical specifications for such materials as well as troubleshooting for their most common problems.

At the end of this course, participants will know the necessary information about the different advanced concrete materials, what tests should be performed and how to interpret their results, what to look for in specifications, and the troubleshooting of material related problems.

Objectives

The objectives of this course are as follows:

• Provide participants with required information about the newly developed reinforced concrete materials.
• Help them understand the different test methods for various materials and interpret their test results.
• Assist participants to effectively consult the technical specifications of these materials.
• Provide them with troubleshooting methods for material-related problems.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

This course is targeted for design engineers, architects, supervision engineers, and inspectors from public agencies and private sector. This course is also essential for contractors, project engineers, and other construction staff
