Yeah, we rod the cylinders normally. That takes times. 25 tamps at three different levels. 30 raps with a mallet etc. The spec shows we can also just vibrate them. So we put them all on a shake table this time. Much quicker. Inside the broken cylinders they were pretty solid and homogeneous.

I tested 8 cylinders of two ages and 4 mixes today. Shooting for 1500 to 1650 psi. So I think I have it bracketed. Turns out the fancy additives we tried were no better than simple calcium chloride.
