Here are a couple pictures of the awards I have been studiobuild with for Kansas City Home Design Magazine.
The concrete/mortar for the regular awards has a little higher paste content than normal with a little silica fume for higher strength. There is also a ton of non-chloride accelerator so we can demold them quickly. They achieve over 4000 psi in four hours.
The Ed Tanner awards are 100% crushed glass (beer bottles from my garage) with a blend of slag and fly ash. Since there is no cement, the slag was heat activated to achieve the desired strength.
