Architecture Building Materials and Construction 2 — Questions and Answers
Question 1: Which masonry bond pattern is considered the strongest for loadbearing walls?
- Running bond
- Stack bond
- English bond (Correct answer)
- Flemish bond
Correct answer: English bond
English bond, with alternating courses of headers and stretchers, provides superior interlocking and is among the strongest masonry patterns.
Question 2: What is the purpose of a weep hole in masonry cavity walls?
- Ventilation only
- Structural anchoring
- Draining water from the cavity (Correct answer)
- Expansion relief
Correct answer: Draining water from the cavity
Weep holes are small openings at the base of masonry cavity walls that allow any infiltrated water to drain out and prevent moisture buildup.
Question 3: What is the difference between tempered glass and laminated glass?
- Tempered is heat-treated; laminated has an interlayer holding shards together (Correct answer)
- Tempered has a PVB interlayer; laminated is heat-treated
- They are functionally identical
- Tempered is used for insulation; laminated for fire resistance
Correct answer: Tempered is heat-treated; laminated has an interlayer holding shards together
Tempered glass is thermally or chemically strengthened and shatters into small pebbles; laminated glass has a PVB interlayer that holds fragments together if broken.
Question 4: Concrete with a water-to-cement ratio below 0.40 is generally considered:
- Weak and porous
- High-strength and low permeability (Correct answer)
- Self-leveling
- Lightweight
Correct answer: High-strength and low permeability
A low water-to-cement ratio produces a denser concrete matrix with higher compressive strength and reduced permeability.
Question 5: Which roofing material offers the longest expected service life in US climate zones?
- Asphalt shingles
- Wood shakes
- Slate (Correct answer)
- EPDM membrane
Correct answer: Slate
Natural slate roofing can last 75–150 years when properly installed, far exceeding most other roofing materials in service life.
Question 6: What is the primary structural advantage of post-tensioned concrete over conventionally reinforced concrete?
- Lower material cost
- Reduced slab thickness for the same span (Correct answer)
- Easier formwork
- Better fire resistance
Correct answer: Reduced slab thickness for the same span
Post-tensioning applies compressive stress to concrete slabs, allowing thinner slabs to span greater distances than conventional reinforcement.
