5. SHAPE
Different crushing
techniques alter the shape
of a terrazzo chip, adding
new design opportunities
for a terrazzo finish.
For example, depicted is
TERRAZZCO's Frozen Blue
aggregate. With a jaw
crusher and a cone
crusher, the aggregate is
reduced in size and forms
a specific shape.
The cone crusher (left
Image) forms a round-
shaped design. In
contrast, the jaw crusher
(right Image) forms an
elongated and jagged
shaped design.

6. STANDARD AGGREGATES
Standard aggregates are the most commonly-used terrazzo
chips. They are labeled as #0, #1 and #2 chips.
Thin-set resinous systems, such as epoxy terrazzo, typically use
#0 and #1 chips for 1/4" thick toppings, and #0, #1 and #2 for
3/8" thick toppings. All marble, recycled glass, and exotic
seashells can be crushed down to the available sizes.

7. VENETIAN AGGREGATES
Venetian terrazzo chips range from size #3 to size #8. These
chips are common among cementitious terrazzo finishes, but can
also be used in an epoxy terrazzo design.
Venetian terrazzo is adored by interior designers around the
world for its unique look. Palladiana terrazzo is a mosaic finish
where large chips or slabs are set in place and standard terrazzo
fill in between the joints.

8. MICRO-AGGREGATES
Micro-aggregates are chip sizes below the standard #0. From
sizes #0 minus, #00 and #000, these chips are noticeably finer
for a more uniformed, even perhaps a more elegant looking
terrazzo finish. The use of micro-aggregates allows for a quick
and easy installation when combined with epoxy terrazzo.

9. CONCORD TERRAZZO COMPANY
