Concrete

absorption

Building materials; Concrete

The process by which water is absorbed. The amount of water absorbed under specific conditions, usually expressed as percentage of the dry weight of the material.

accelerator

Building materials; Concrete

An admixture which, when added to concrete, mortar, or grout, increases the rate of hydration of the hydraulic cement, shortens the time of set and increases the rate of hardening or strength.

adiabatic curing

Building materials; Concrete

The maintenance of ambient conditions during the setting and hardening of concrete so that heat is neither lost nor gained from the surroundings of the concrete.

A material other than water, aggregates, and Portland cement that is used as an ingredient of concrete, and is added to the batch in small doses immediately before or during the mixing operation to ...

expansion joint

Building materials; Concrete

A surface divider joint that provides space for the surface to expand. It is usually composed of a fibrous material (~1/2" thick) and often installed in and around a concrete slab to permit it to ...

entrapped air

Building materials; Concrete

Air in concrete which is not purposely en-trained. Entrapped air bubbles are normally much larger and more irregular than entrained air bubbles.

entrained air

Building materials; Concrete

Microscopic air bubbles intentionally incorporated in mortar or concrete, to improve workability and durability (usually producing a higher degree of resistance to freezing and thawing).
