Difficulty: Easy
Correct Answer: Terrazzo floor
Explanation:
Introduction / Context:
Architectural flooring names reflect composition and finishing method. Terrazzo is a composite of marble (or stone) chips in a cementitious or resin matrix, ground and polished to expose the aggregates. The chip size may be small (for example, around 3 mm), producing a fine, speckled aesthetic with durable performance.
Given Data / Assumptions:
Concept / Approach:
Terrazzo distinguishes itself from generic “mosaic” by its composite slab laid in situ or precast tiles, then polished to reveal chips uniformly. A “marble slab floor” uses whole slabs, not chips. “Cement screed floor” is plain binder without decorative aggregates. Thus, the described finish aligns with terrazzo.
Step-by-Step Solution:
Verification / Alternative check:
Industry specifications and BOQ items list “in-situ terrazzo” or “terrazzo tiles” with chip grading and binder ratio; polishing steps are standardized.
Why Other Options Are Wrong:
Mosaic can refer to patterned tile assemblages rather than in-situ chip-and-binder flooring; “chips floor” is informal; marble slab floor uses full slabs; cement screed lacks chips.
Common Pitfalls:
Confusing terrazzo with mosaic tiles; ignoring curing and grinding requirements that affect durability and finish quality.
Final Answer:
Terrazzo floor
