There is a very large data base available in the marine aspect of fero cement
i was told to look for two things while taking test cores first being sand - improperly mixed concrete can lead to pockets of sand
second is the amount of "fero" or steel - in a well executed panel there is more steel than cement - A tight mesh of steel - having the voids filled with concrete
as the price of steel went up this method fell out of favor due to cost of the steel - good ferro is maybe 75% steel and 25% concrete by weight
lloyds of london may inspect while building to certify the structure has enough steel to be safe from fracture or crumbling - the wrote the specs I believe
