Concrete Building Technology 1 - Key Terminology

These flashcards include key vocabulary and definitions related to concrete technology, covering various aspects including types, components, and tests.

Artificial stonelike building material made by mixing cement and various mineral aggregates with sufficient water.

Concrete

Concrete having no reinforcement or reinforced only for drying shrinkage or thermal stresses.

Plain Concrete

Concrete in which steel reinforcement is embedded to work together with the concrete.

Reinforced Concrete

A material used to form materials into a cohesive whole, providing structural stability.

Binder

Various hard, inert mineral materials like sand and gravel added to a cement paste to make concrete.

Aggregate

A mixture of cement and water.

Cement Paste

Cement that sets and hardens through a reaction with water.

Hydraulic Cement

A by-product material formed when iron is smelted.

Blast-Furnace Slag

An admixture that disperses air in a concrete mix to improve workability.

Air-Entraining Agent

Method for determining the workability and consistency of freshly mixed concrete.

Slump Test

The resistance of a material to breaking under tension, which is relatively low in concrete.

Tensile Strength

Concrete that utilizes fly ash to enhance performance.

High Volume Fly Ash (HVFA) Concrete

Cement that increases in volume after setting.

Expansive Cement

Chemical reactions within concrete that can lead to cracking.

Chemical Attack

The process of a substance chemically combining with water.

Hydration

An expansive reaction when the cement matrix contacts sulfates in the environment.

Sulfate Action

The ratio of mixing water to cement in a unit volume of concrete.

Water-Cement Ratio
