1. A terrazzo installer working in Maryland is most likely required to
understand which primary purpose of terrazzo flooring systems?
A. Electrical grounding for commercial buildings
B. Structural load-bearing reinforcement for slabs
C. Decorative and durable composite flooring composed of chips set in
a binder
D. A decorative flooring system made from marble, quartz, granite, or
glass chips embedded in cement or resin binder
Terrazzo flooring is a composite material primarily used for
decorative, durable surfaces where chips of stone or glass are
embedded in a cementitious or epoxy binder and then polished for
finish quality.
2. Which of the following best describes the traditional composition of
cement-based terrazzo?
A. Rubber particles and synthetic adhesive
B. Pure epoxy and steel mesh reinforcement
C. Vinyl sheets with adhesive backing
D. Marble chips embedded in a cement matrix
, Cement-based terrazzo traditionally consists of marble or aggregate
chips embedded in a cement binder, which is then ground and
polished to a smooth finish.
3. What is the primary advantage of epoxy terrazzo compared to cement-
based terrazzo?
A. It requires no polishing or finishing
B. It is always cheaper and easier to install
C. It cannot be used indoors
D. It allows thinner installation and greater color flexibility
Epoxy terrazzo is thinner, lighter, and offers more design flexibility
and color options compared to cement-based terrazzo systems.
4. Which tool is most commonly used in terrazzo grinding and polishing
operations?
A. Hammer drill
B. Tile cutter
C. Paint sprayer
D. Planetary grinder with diamond abrasives
Terrazzo finishing requires specialized grinding machines equipped
with diamond abrasives to achieve a smooth and polished surface.
5. What is the purpose of divider strips in terrazzo installation?
A. To improve electrical conductivity
B. To increase adhesive curing speed
C. To prevent moisture absorption
D. To create design patterns and control cracking
Divider strips separate sections of terrazzo, forming patterns and
helping control cracking due to movement or shrinkage.
6. Which safety equipment is essential when grinding terrazzo floors?
A. Sandals and gloves
B. Hard hat only
, C. Sunglasses only
D. Respirator, hearing protection, and eye protection
Grinding terrazzo produces dust and noise, making respiratory,
auditory, and eye protection essential for worker safety.
7. What is the typical curing time before grinding cement-based terrazzo?
A. Immediately after pouring
B. 1–2 hours
C. 24 hours
D. Several days to weeks depending on conditions
Cement-based terrazzo must fully cure before grinding, often
requiring several days or longer to achieve proper hardness.
8. What is the main function of a terrazzo matrix binder?
A. To color the aggregates only
B. To reduce floor thickness
C. To increase electrical resistance
D. To bind aggregates into a solid, durable surface
The binder holds decorative chips together, forming a unified and
durable flooring system.
9. Which of the following is a common aggregate used in terrazzo?
A. Wood chips
B. Plastic pellets
C. Paper fibers
D. Marble chips
Marble chips are one of the most commonly used aggregates in
terrazzo flooring systems due to their durability and aesthetic appeal.
10. What is the purpose of grinding terrazzo after installation?
A. To remove divider strips
B. To change the chemical composition
C. To reduce floor weight
