Dear Mr. Rose (and apologies to those for whom this subject is of no
There should be no serious problems. Concrete, as you no doubt are
aware, is a 3-part mixture of aggregate, sand and mortar. The cheaper
the concrete the less the proportion of mortar. So two out of three are
inert, and locally are liable to be made of limestone anyway.
Some years back, working in the centre of marine biodiversity (north of
Java) Evan Edinger tested settling panels made of different materials:
found concrete to be preferred just behind dead coral as a substrate.
In a somewhat more detailed study of concrete as a substrate, Scott
Moser and Risk (Mar Poll Bull, maybe 15 years ago) found that some
critters avoided the mortar, some loved it, and some didn't care.
