I tell the younger engineers with whom I work, "primum non nocere". The statement is attributed to Hippocrates of Kos. "First do no harm"
The irony in the above statement is that Hippocrates of Kos lived from about 460 BC until 370 BC and was Greek, the quote attributed to him is generally in Latin. Hippocrates never spoke Latin. This is a real knee slapper in some academic circles. At least that is what Hippocrates told me.
In discussing this further with a philosophy professor colleague, he informed me that in Roman times, students studied all subjects in Latin. The exception was philosophy which was studied in Greek. It wasn't until middle ages that all scholastics were studied in Latin, and the works of the classic Greek philosophers were translated from Greek into Latin. Up into the 1800's both Greek and Latin were required in most colleges.
...just a bit of an interesting tidbit on a Friday.

Question for the concrete repair experts:
An 80-year old concrete building with cantilevered concrete balconies. Tops of the slabs have sound waterproofing coating but water has penetration the sides of the slab and caused rusting of the edge rebar which in turn caused spalling of concrete.
I want to chip away the unsound concrete, wire brush the exposed rebar, then coat the rebar and newly exposed concrete with a sealer, then apply a mortar with some type of additive (epoxy, polyester, or a polymer like latex). Then a concrete sealer.
Any suggestions on the repair methodology or product recommendations?
