TRAINING.

Overview

After participating in this course, you will be able to do the following:

• Apply modern concrete technology in concrete projects
• Develop performance specifications for concrete projects
• Create more durable and sustainable concrete mix designs
• Select suitable test methods to evaluate concrete performance
• Interpret quality control data results for fresh and hardened concrete

Description:

The premature deterioration of civil infrastructure has created a colossal backlog of ageing concrete structures. Professionals need to design structures that can exceed their service life even in harsh environments and with minimum maintenance and repair. This, however, requires a solid understanding of concrete technology and the interaction between structures and their environment.

This course consists of several workshops which provide state-of-the-art knowledge on durable and sustainable concrete, including mineral additions and chemical admixtures that enhance the workability, strength, and durability of concrete. The workshops will also enhance your decision-making process regarding various concrete products, construction procedures and performance test methods.

Course Outline:

• Cement chemistry, hydration and microstructure
• Supplementary cementitious materials
• Concrete chemical admixtures
• Workability of fresh concrete
• Concrete mixture design
• Concrete test methods and quality control
• Modern concrete: HPC, SCC, FRC, UHPC, mass concrete and thermal stress, pervious concrete and shotcrete
• Service life prediction
• Concrete construction sustainability

Who Should Attend
Project Managers • Civil and Asset Engineers • Construction and Quality Engineers • Design Engineers • Technicians and Technologists • Plant and Facility Engineers • Business Owners
