aerated

Not just in looks — though a frosting should be aerated and smooth, with enough firmness to hold shape — but also in taste.

When the capsules are round, they scatter light, making the liquid opaque, much like air bubbles make aerated water appear white.

More than 40 households have been advised to evacuate after issues with reinforced autoclaved aerated concrete were found.

A total of 231 schools in England were confirmed to have Raac, or reinforced autoclaved aerated concrete, in the most recent government list issued last month, but that list could continue to grow.

It is a cheaper alternative to standard concrete, is quicker to produce, easier to install and aerated.
