RCON2? is a non-destructive testing
device that measures the electrical resistivity of concrete samples.
Resistivity has been shown to be an excellent method for evaluating the
micro-structural properties of concrete, including: diffusion of chloride in
concrete; rebar corrosion in concrete; setting time of fresh concrete; curing
of concrete; moisture transfer in concrete; cathodic protection design, and
crack detection in concrete.
Since RCON2 is a non-destructive testing method and requires no
special sample prep, it can utilize the same samples that are currently being
used for compressive strength testing without affecting that test.
RCON2 is fast (measurement time is less than 5 seconds), accurate
(±2%, utilizing variable frequency method) and flexible (the measurement can be
taken with different settings and test configurations). It also allows for
continuous measurement of electrical resistivity over time, which can be used
to monitor several other parameters such as the changes of water content and
time of setting in concrete specimens.
In concrete materials, electrical
resistivity has been well correlated with important durability parameters such
as permeability and diffusivity. In addition, this non-destructive test can
easily be conducted on fresh or hardened concrete specimens at different ages
or various stages of hydration in order to study workability, setting times and
durability performance of the concrete. The electrical resistivity method has
also been applied to investigate corrosion of rebar in concrete, creep,
aggregate segregation and freeze/thaw of concrete since they affect the pore
network properties. The concrete electrical resistivity techniques is also a
suitable replacement for the rapid chloride permeability test of concrete (as
per ASTM C1202) since there is a strong correlation between the electrical
resistivity and durability performance of concrete.
