We
are taking the opportunity to go over some concrete
terminology and in our previous blog did not even make it past the first letter
of the alphabet. Here is an additional look at some essential concrete
terminology that is taken from the American Concrete Institute’s ACI Concrete Terminology.
Backfill
concrete — nonstructural concrete used to over-fill excavated pockets in rock
or to prepare a surface to receive structural concrete
Basic
creep — creep that occurs without migration of moisture to or from the concrete.
Batch
— (1) quantity of material mixed at one time or in one continuous process; (2)
to weigh or volumetrically measure and introduce into the mixer the ingredients
for a quantity of material
Binary
mixture — concrete containing two cementitious materials
Blended
cement — a hydraulic cement consisting of portland cement uniformly mixed with
slag
cement or pozzolan, or both
Calcium
chloride — CaCl2, a crystalline solid, is primarily used in concrete as an
accelerating admixture.
Calcium
stearate — Ca(C18H35O2)2, commonly marketed in powder form, insoluble in water,
used as a water repellent admixture in concrete
Cast-in-place
concrete — concrete that is deposited and allowed to harden in the place where
it is required to be in the completed structure, as opposed to precast concrete
Cement
paste — binder of concrete and mortar consisting essentially of cement, water,
hydration products, and any admixtures together with very finely divided
materials included in the aggregates
Coarse
aggregate — aggregate predominantly retained on the 4.75 mm (No. 4) sieve or that
portion retained on the 4.75 mm (No. 4) sieve.
Concrete
compressive strength — the measured maximum resistance of a concrete specimen
to axial compressive loading and expressed as force per unit cross sectional
area
Curing
— action taken to maintain moisture and temperature conditions in a freshly
placed cementitious mixture to allow hydraulic cement hydration and (if
applicable) pozzolanic reactions to occur so that the potential properties of
the mixture may develop
Drying
shrinkage — shrinkage resulting from loss of moisture
Durability
— the ability of a material to resist weathering action, chemical attack,
abrasion, and other conditions of service
