Fly-ash is a common additive to cement or concrete and so it would not 
surprise me it makes its way into cinder blocks as well, though probably not 
as the sole or even major constituent part.

But I second the idea to skip fancy bed edges. A good layer of mulch on the 
edges stops any errosion. Though you may not be able to get that waist high 
effect. But the Ausie permaculturists are fond of using large culvert rings 
for their zone 0 kitchen gardens. The galvanizing makes me cringe but the 
functional and aesthetic effect is very nice.
