Which type of concrete is reinforced with steel fibers to improve tensile strength?
Answer: Fiber-reinforced concrete
Fiber-reinforced concrete incorporates steel or synthetic fibers to enhance tensile strength and crack resistance.
What is the R-value used to measure in building materials?
Answer: Thermal resistance
R-value measures a material's thermal resistance — the higher the R-value, the better the insulation performance.
Which structural material has the highest strength-to-weight ratio?
Answer: Structural steel
Structural steel offers an exceptionally high strength-to-weight ratio, making it ideal for long spans and tall buildings.
What is the primary purpose of a vapor barrier in wall assemblies?
Answer: Preventing moisture migration
A vapor barrier retards the diffusion of water vapor through wall assemblies, protecting insulation and framing from moisture damage.
Engineered lumber products like LVL and PSL are primarily used for what purpose?
Answer: Structural beams and headers
Laminated Veneer Lumber (LVL) and Parallel Strand Lumber (PSL) are engineered wood products used as structural beams and headers due to their high strength and dimensional stability.
What does STC rating measure in building assemblies?
Answer: Sound Transmission Class between spaces
Sound Transmission Class (STC) is a rating that quantifies how well a building partition reduces airborne sound.
