4.17.2 Cast Stone (Dry -Tamped) Attributes.
Material. Cast or dry-tamped stone is an almost dry
cement, lime, and aggregate mixture that is dry tamped
into a mold to produce a dense, stone-like unit.
(Sometimes, cast stone is used as a generic term for
precast concrete, but there are differences.) The outer
surface of dry-tamped cast stone looks very much like
stone. The inner core can be either dry-tamped or poured
full of concrete, and reinforcing bars and anchoring
devices can be added during fabrication.
Uses. Cast Stone can be used as a replacement for
unveined, deteriorated stone (e.g., sandstone, brownstone)
or terra cotta that imitates stone. It can also be used
for surface wall stones or for ornamental features such as
window and door surrounds, voussoirs, brackets, and hoods.
Closely resembles stone texture when made with good
molds and fabrication;
Expansion/contraction similar to stone;
Minimal shrinkage of material;
Anchors and reinforcing bars can be built in;
Material is fire-rated;
Range of color available;
Heavy units may require additional anchorage;
Color can fade in sunlight;
May be more absorbent than natural stone;
Replacement stones are obvious if too few models and
molds are made.
