Hypertufa is a light-weight concrete 'artificial stone' with peat (or
other light weight material) substituted for the gravel used in
conventional concrete - formulas vary but a typical formula is:
1-2 parts sharp sand
2 parts peat moss
1 part portland cement
mix sand, peat, and cement thoroughly (NO lumps!). Gradually add water to
dampen - mixture should be just damp enough to stick together when
squeezed *without* dripping any water. Press *firmly* into form. Allow
minimum of 24-48 hours before removing form and at least two weeks curing
time *without* drying out.
Perlite may be used in place of half the sand to reduce weight but finish
will be less stone-like.
