“Low Carbon Concrete” is the new mantra for our industry, yet many people are unaware that much of the concrete we produce now has a greatly reduced carbon footprint than that of 50 years ago. The factor being that no-one was counting this before. The webinar will look at that point, along with the use of silica fume, especially in conjunction with other SCMs. By improving the overall performance of the concrete – strength and durability parameters – the longevity of the concrete is increased, resulting in less ‘new’ concrete being produced for repairs or rebuilds.

Silica Fume is a key component of multiple blend systems, where the higher reactivity compensates for the slower pozzolanic action of Fly Ash or Slag cement. The synergistic pozzolanic effects in the short and long term mean high performance concrete can be produced with much lower Portland cement contents with a cumulative reduction of the CO2 from each SCM.

Reference projects will be shown where the CO2 levels have been calculated for comparison and where the cost effectiveness is outlined.

Learning Objectives:

1. Describe how silica fume enhances mechanical and durability properties of concrete.

2. Explain the role of silica fume, and other SCMs, in reducing the carbon footprint of concrete.

3. Describe the increased performance benefits from binary, ternary and quaternary cementitious blends, in addition to being ‘low carbon concrete’.

4. Outline how to balance low carbon, performance and economics when producing concrete at all levels.
