Construction Materials & Testing Practice Flashcards

A set of vocabulary flashcards covering the fundamental materials, testing procedures, and standards used in civil engineering and construction.

Construction Materials

Any substances used to build structures, ranging from residential homes to bridges and highways, chosen based on cost-effectiveness, availability, and performance.

Material Testing

The systematic evaluation of building materials to verify they meet design specifications and safety standards, allowing for the identification of faults before a structure is loaded.

Metals

A core category of materials including steel, aluminum, and iron used specifically for structural framing and reinforcement.

Concrete

A composite material composed of cement, water, fine aggregate, and coarse aggregate.

Compressive Strength

A major property of concrete tested at $7$ and $28$ days using cylinder or cube specimens.

Workability (Slump Test)

The measure of fresh concrete consistency before it is placed.

Durability

The resistance of material, specifically concrete, to freeze-thaw cycles, chemical attack, and abrasion.

Aggregates

Materials that make up 60\text{--}75\text{%} of concrete volume and form the backbone of concrete and asphalt mixes.

Coarse Aggregate

Material such as gravel or crushed stone that is retained on a $4.75\text{ }mm$ sieve.

Fine Aggregate

Material such as natural or manufactured sand that passes through a $4.75\text{ }mm$ sieve.

Asphalts

Bituminous materials used in road construction and waterproofing applications, often designed using the Marshall or Superpave methods.

Marshall Stability

A test used to measure the load resistance of compacted asphalt specimens.

Wood

Natural and engineered timber, such as LVL and plywood, used in framing, formwork, and finishes.

Plastics & Synthetics

Materials including PVC, polymers, and composites (like HDPE) used for piping, insulation, and modern construction systems.

Universal Testing Machine (UTM)

A key testing instrument used to measure tension, compression, and flexure on metals and concrete.

Slump Cone & Compaction Factor

Equipment used to evaluate the workability of fresh concrete on-site.

ASTM and AASHTO

Standardized procedures and regulatory bodies that ensure consistency, safety, and compliance in material testing.
