Burn (or cook) limestone to remove co2=quick lime. (Throw limestone
blocks into a fire as the Romans did). Add water and sand/pebbles and
the cement takes co2 out of the air making a true bonded adhesive.
AFAIK. It has only been 50 years.

The old fashioned way was quicklime. I don't know what it is, other

The old lime mortar was quicklime, with water added to make hydrated
lime. Hydrated lime is what is sold now for mortar and other uses.
Quicklime would be a strong base, similar to lye.
Two weeks ago, we noticed a dead raccoon on the edge of the pavement.
This is the season, so... it sat there and I expected it to stink very
bad in the hot sun and humidity. Nope. Five days latter, the bones
were stripped white and the flesh had dissolved, no bugs, no maggots,
no odor. I am thinking someone put some sort of chemical on the
carcass and dissolved the flesh - perhaps that is a new critter
control technology being employed by the County? Is this a new
product to purchase at the Ace Hardware store?
Thanks.
