Here are some basic terms and expressions that you have to take into account.
An admixture that will shorten the set time of concrete.
A material other than water, cement, and aggregate, used to modify concrete's freshly mixed, setting, or hardened properties.
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.
Production of a quantity of concrete based on volume,ie.. a cubic yard.
The measured amount of sand, stone, cement, and water that make up a batch or "load" of concrete.
Usually cylindrical in shape. Part of a footing or foundation.
A 32% solution or a solid, when added to concrete acts as a set accelerator.
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.
Having cementing qualities.
Graded granular material with a nominal maximum size ranging from 1 1/2" down to 3/8".
a mixture of sand, stone, cement and water.
A graded granular material entirely passing the 3/8" sieve.
An admixture that can produce a high slump concrete or produce considerable reduction of water with a minimal effect to set time.
A low density aggregate such as expanded clay or shale, used in lightweight concrete.
An admixture that will lengthen the set time of concrete.
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.
see High Range Water Reducer
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.
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.
the weight of the total amount of water relative to the weight of the total amount of cement used per cubic yard of concrete.
certified by the National Organization for Construction Standardization and Certification.
labs quality certified by the Mexican Certification Agency (Entidad Mexicana de Acreditación, EMA).

AGC of America:
The Wyoming Chapter of the Associated General Contractors of America (AGC) Recognized GCC Dacotah with a Safety Award for compiling a Zero Incident Rate for 25,000 hours worked.
This award is given to locations where all the critical loss prevention measures have been implemented to protect buildings, machinery and contents of possible losses either by human factors or natural hazards, making the Rapid City Plant the first cement plant from GCC both America and Mexico Divisions to achieve this award and one of the few Cement plants in the United States insured by FM Global to have such recognition. 2016
