Cement production accounts for 8% of global emissions, and it will rise as nations get richer and build more. It’s mainly because of the energy needed for the high heat process, and the carbon released from the limestone used. Studies have found that replacing limestone with volcanic rocks significantly reduces the emissions as no carbon is released during the chemical process. It also requires low operating temperatures.
Lava concrete is not prone to shrink-cracking than regular concrete because it is so dry when installed, meaning that less water has to evaporate in the cure.
