CCS Materials Selection 2

Question 1

Which ASTM standard governs the standard specification for portland cement?

Accepted Answer

ASTM C150

Answer

ASTM C150 is the Standard Specification for Portland Cement, covering eight types of hydraulic cement.

Question 2

A specifier selecting reinforcing steel for a project in a coastal environment should prioritize which material property above all others?

Accepted Answer

Corrosion resistance

Answer

Coastal environments expose steel to chloride-laden air, making corrosion resistance the primary selection criterion to ensure long-term durability.

Question 3

When specifying stone veneer for exterior cladding, which property is most critical in freeze-thaw climates?

Accepted Answer

Absorption rate

Answer

Low water absorption limits moisture intrusion and reduces the risk of spalling caused by freeze-thaw cycling within the stone.

Question 4

Which document type best communicates mandatory material performance requirements to a contractor without dictating the specific product brand?

Accepted Answer

Performance specification

Answer

A performance specification defines required end-result criteria, allowing any product that meets those criteria to be used.

Question 5

A Life Cycle Assessment (LCA) of a building material primarily evaluates which aspect?

Accepted Answer

Environmental impacts from raw material extraction through end-of-life disposal

Answer

An LCA quantifies environmental burdens—energy, emissions, waste—across every stage of a product's life from cradle to grave.
