Successful concrete starts with an understanding of the way in which clear specification progresses through the selection and proportioning of suitable materials to meet the demands placed on concrete structures to perform well in an aggressive world.
The European Standard BS EN 206-1 together with the supplementary British Standard BS 8500, both of which should now become familiar to professionals engaged in the writing and interpretation of concrete specifications.
This course explains the principles of the standards and how to achieve durable concrete.
Aims & Objectives:
At the end of this course delegates will understand the principle in BS 8500 and its associated documents. They will be able to specify concrete to be durable in its intended environment.
At the end of the course delegates will:
- Know how BS 8500, EN 206-1 and SD 1 work together
- Understand the terminology in BS 8500
- Understand the differences between the concrete types
- Be able to identify the durability requirements for particular situations
- Understand how to specify concrete to meet the durability requirements
- Appreciate how to ensure the concrete meets the specification
