I found the "recipe" for small batch concrete. This was used one of our jobs
a few years ago and the six cylinders tested averaged out to 4,131 psi
strength.
This will make 1/4 cubic yard. Add just enough water to be able to thoroughy
mix the ingredients, maybe a smidgeon more if you can't float it out:
3-1/2 cubic feet of sand
5 cubic feet of small stone (could be larger than pea-gravel)
2 bags of portland cement
