equipment required.
-
Utilizes only two environmentally safe
dyes.
-
Identifies ASR in concrete and
differentiates ASR from other causes of degradation.

Results obtained in less than five
minutes are easy to interpret.
-
Economic, fast and easy to use.
Field Test to
identify Alkali Silica Reaction (ASR) in concrete. Two reagents are
applied to the broken surface of a concrete core and the excess rinsed
off. On contaminated concrete, the resultant stains reveal the presence
of ASR. The stains also reveal the extent of the ASR in the concrete and
indicate the stage of ASR progression. Yellow indicates that
degradation has begun; pink warns that degradation is advancing.
ASR Detect™
is both a practical and a scientific tool. It's principal
application is analyzing existing concrete structures. By identifying
ASR deterioration in its earliest stages,
ASR Detect™ facilitates the
problem being identified when remediation techniques can be applied; for
example, treating the concrete with a lithium-bearing solution to
inhibit further deterioration. Where deterioration is advanced,
ASR
Detect
™ provides a clear picture of the extent and depth of the damage.
As a
scientific tool,
ASR Detect™ can be applied to improving the
understanding of where, how and why ASR
occurs. That
understanding is basic to developing ASR preventatives that allow
high-alkali cements or poor-quality aggregates to be used in concrete
mixes without risking the development of ASR.
Simply apply
each of the two reagents to the broken surface of a concrete core
drilled in a suspect structure
, and rinse
off the excess. On ASR contaminated concrete, the resultant stains
reveal the presence of ASR.
The stains™
distribution shows the
extent of ASR in the concrete, and their proximity to different
components of the aggregate gives clues to the source of trouble. The
two gels that are identified
- one staining
yellow, the other pink - indicate the stage of ASR™ progression. Yellow
signals that degradation has begun. Pink warns that degradation is
advancing.
Typically, ASR occurs in cracks and
these cracks often cut
through the aggregate and usually do not follow the aggregate-paste
boundaries. ASR tends to fill air voids.
In contrast to
the two established methods of
ASR Detect™ion-petrographic analysis
and
uranyl acetate
analysis,
ASR Detect™ has numerous benefits.
Because the
reagent stains are clearly visible even before the treated sample dries,
a complete diagnosis is possible in less than 5 minutes.
ASR Detect™
systems are relatively inexpensive.
Petrographic analysis
requires shipment to a laboratory, adding time and raising the costs to
hundreds of dollars per sample, also the
uranyl acetate
reagent is almost prohibitively expensive.
ASR Detect™ is simple enough
to use in the field. Its reagent stains are visible to the naked eye and
are distinctive enough to be recognized and interpreted by anyone with
minimal training.
Petrographic analysis
requires specially trained technicians working in a well equipped
laboratory. Therefore, the use of
ASR Detect™ can considerably reduce
the cost of diagnosis by reducing drastically the need for
petrographic analysis.
The ASR
Detect
™ reagents present minimal danger to either human health or the
environment.
Uranyl acetate is
radioactive and contains a heavy metal and therefore, has the potential
to cause health and disposal problems.
ASR Detect™
provides information not only about the presence but also the severity
of ASR. Its affordability allows an engineer to analyze enough samples
to obtain an accurate diagnostic picture of an entire structure. The
high cost of a
petrographic analysis
permits only a limited number of samples to be examined.
