DEFINITIONS
**************************************************************************
NOTE: See ACI 201.1 for definitions of various types
of concrete deterioration.
**************************************************************************
1.2.1
Concrete
A mixture of binder material, water,
and fine and coarse aggregate, with
or without admixtures.
1.2.2
Mortar
A mixture of binder material, water, and fine aggregate, with or without
admixtures.
1.2.3
Grout
A mixture of binder material and water, with or without a filler.
1.2.4
Cement-Based Material
A material consisting of portland cement and/or other cementitious
materials as a binder and aggregate. As used in this specification,
cement-based materials do not include materials with polymer modifiers.
1.2.5
Polymer-Modifier
A polymer used to modify the properties of a cement-based concrete or
mortar. The polymers commonly associated with concrete rehabilitation are
styrene-butadiene and acrylic latex.
1.2.6
Polymer-Modified Material
A combination of polymer, portland cement and/or other cementitious
materials, and fine and/or coarse aggregate. Polymer-modified concrete is
normally placed to a thickness of 25 mm (1 inch)1 inch or greater.
Polymer-modified mortar is normally placed to a thickness of less than 25
mm (1 inch)1 inch.
1.2.7
Epoxy Resin Binder
A two-component epoxy resin binder system in low and medium viscosities
used by itself as a primer or for producing epoxy concrete or mortars when
mixed with aggregate.
1.2.8
Epoxy Concrete
A combination of epoxy resin and fine and coarse aggregate.
1.2.9
Epoxy Mortar
A combination of epoxy resin, a mineral filler, and fine aggregate.
1.2.10
Non-Pressure Epoxy Grout
A combination of epoxy resin binder, a mineral filler and a thixotropic
agent.
