Stanford’s low-carbon cement swaps limestone for volcanic rock

Scientists at Stanford are exploring how volcanic rock might be used to lower the carbon footprint of cement

The notoriously large carbon footprint of cement production is a prime target for researchers looking to chip away at the problem of climate change, and we’ve seen how this could involve all kinds of tweaks to the recipe. Scientists at Stanford University have demonstrated yet another one that substitutes troublesome limestone in Portland cement with zero-carbon volcanic rock, which might just help reinforce the finished product.
