I love these base-level, practical advances where even a slight improvement in a formula (provided it is not closely guarded) can, say, improve the strength of a material by 5-10%, meaning that much less of it must be used, which at a scale like concrete's can make for huge changes in usage, markets, processes etc.
Concrete is a HUGE greenhouse gas source, so this is also a great boon for the environment. It's estimated that concrete is responsible for 5% of all anthropogenic CO2.
