Making Concrete Faux-stone

• Making Rock
• Homemade Concrete Formula for Artificial Rock - best source I've seen for a variety of formulas for types of stones.
  • Mix 1 part cement, 2 parts sand and 3 parts gravel to make a dry basic concrete mix. Add enough water to create a sloppy consistency, such as that of thick pancake batter, if you plan to pour the concrete into molds. Or stop adding water when the consistency resembles cream cheese if you plan to spread concrete over the inside walls of the molds to make hollow rocks. Continue mixing until the mixture is smooth and free of lumps.
  • Mix 1 part cement and 2 parts white or gray sand to create smooth, fine-textured faux rocks. Add enough water to achieve the required consistency.
  • Mix 2 parts cement, 3 parts sand and 3 parts perlite for a pock-marked effect. Add water until the mixture is crumbly like cookie dough. Press the mixture into the mold. Trapped air bubbles don't matter because they add to the effect.
  • Mix 1 part sand, 1 part cement and 2 parts composted bark or peatmoss to make hypertufa, which resembles a naturally porous, light rock called tufa. Add enough water to create a spreadable consistency.
  • Mix 1 part sand, 1 part cement and 1 part peatmoss or composted bark, and then mix in water, to make hypertufa that resembles limestone.
  • Mix 5 parts sand, 2 parts cement and 3 parts peatmoss or composted bark for hypertufa that resembles sandstone. Add water and mix.

• Best Recipe for Making These Steps? - discussion about best way to create faux-stone steps. Consensus seemed to be to use concrete rather than hypertufa. I don't know why… strength?
• Perlite Concrete - locally saved from source.
• Hypertufa - "Hypertufa (pronounced hyper-toofa) is the term used for a type of artificial stone. It was first created in the mid 19th century by mixing sand, peat, various volcanic aggregates and cement. It’s relatively lightweight compared to stone or concrete and no matter how cold your winter temps may be, if properly cured, is freeze proof."
