does limestone's chemical makeup (calcium carbonate CaCO3) weaken concrete somehow?
i thought this interesting so i reviewed the specs from MDOT. they specifically allow the use of shell as an asphalt aggregate. LADOT does not identify that in their standards and specs. i do not know if that is what he was referring to but if you get more info from him please let us know.
