One problem I see with the site, http://www.gardenguides.com/85041-make-concrete-perlite-flower-pots.html, is that they refer to "CEMENT" as concrete, it is plan to see that their mixture is with cement and not "CONCRETE" it would not be like a 'MUD PIE" if it were concrete, which contains cement, sand and stones'.
Otherwise I believe their mixture would work very well, even if you replaced one of the ingredients with paper pulp.
