How Low Carbon concrete Mixes Are Changing the Game

The Built Environment

Concrete might be the backbone of our built environment, but it’s also one of the world’s biggest emitters.

In this episode, Dean sits down with Dylan Viviers from Holcim to unpack how low carbon concrete is reshaping the construction industry from the ground up.

They dig into:

• What low-carbon concrete actually is (and how it performs on site)
• Busting the myths: strength, setting time, and cost
• Holcim’s EcoPact range and how it achieves real carbon reductions
• Using recycled aggregate, admixtures, and new tech
• The road to net zero, and what builders, engineers and architects can do now

If you’re in the trade and ready to build better, this one’s for you.
