Aluminum hit a fresh all-time high of $3,313 amid dwindling inventories and concerns about further supply disruptions. The West's stand-off with Russia over Ukraine has raised prospects of sanctions on one of the world's largest metal suppliers, triggering a rush to aluminum stocks at LME warehouses, which currently sit at roughly 50% of March 2021 levels.

Aluminum in Concrete| Concrete Construction Magazine
Chemically, aluminum will react with the alkalis in concrete (OH) and produce hydrogen bubbles. If you add enough aluminum powder to a full load of concrete, it will spill out of the drum after a little while. Make a cylinder with this concrete and you will notice a mound on top of the cylinder the next day.
