Results
Accelerating Admixture:
An admixture that will shorten the set time of concrete.

Admixture:
A material other than water, cement, and aggregate, used to modify concrete's freshly mixed, setting, or hardened properties.

Aggregate:
A material such as crushed stone, sand, or gravel. When proportionately blended with hydraulic cement and water produces concrete.

Air Entraining Admixture:
An admixture that through agitation in production of fresh concrete causes the development of a system of microscopic air bubbles that increase its workability and aid in freeze/thaw resistance.

Batch:
Production of a quantity of concrete based on volume,ie.. a cubic yard.

Batch Weights:
The measured amount of sand, stone, cement, and water that make up a batch or "load" of concrete.

Caisson:
Usually cylindrical in shape. Part of a footing or foundation.

Calcium Chloride:
A 32% solution or a solid, when added to concrete acts as a set accelerator.

Cement:
Known as Portland Cement, is a hydraulic product, which means it sets and hardens when it chemically interacts with water and is able to do this under water.

Cementitious:
Having cementing qualities.

Coarse Aggregate:
Graded granular material with a nominal maximum size ranging from 1 1/2" down to 3/8".

Concrete:
a mixture of sand, stone, cement and water.

Retarding Admixture:
An admixture that will lengthen the set time of concrete.
Slump:
used to measure the consistency of ready mix concrete. The slump test is done by filling an inverted funnel shaped cone with concrete. When the cone is removed, the concrete "slumps". This distance is measured to determine the slump.

Superplasticzer:
see High Range Water Reducer

Vapor Barrier:
A membrane such as 4 mill plastic placed on grade that when fresh concrete is placed on top of, minimizes the transmission of water vapor into and through the hardened concrete from the subgrade.
Water Reducing Admixture:
An admixture that allows a decrease in water without changing the slump of fresh concrete, or, allows an increase in slump without an increase in water.

Water/Cement Ratio:
the weight of the total amount of water relative to the weight of the total amount of cement used per cubic yard of concrete.
