Concrete Training for Site Agents, Gangers and Technicians in the control of concrete on site
- Concrete Training Programme.
- Review concrete properties, materials, and faults.
- Laboratory practical exercises on concrete testing.
- Syndicate project on early-age cracking.
- Supervision of concrete construction and conformity criteria.
Overview
Concrete Training is a comprehensive 2-day programme focusing on enhancing participants' understanding of concrete properties, materials, and construction faults. The course covers topics such as concrete types, supervision of construction, and conformity criteria. Practical exercises include slump testing, cube making, and evaluating test results. Participants engage in syndicate projects and discussions to apply their knowledge. The course aims to equip individuals with the necessary skills to ensure quality concrete construction practices.
Who should attend
Concrete Supervisors, Inspectors, Engineers
