What an Engineer Should Know About ASR and
Other Aggregate Issues (1 PDH)
Alkali-silica reaction (ASR) is a potentially
deleterious reaction that may occur in concrete.
Three conditions must be present for ASR to form:
the aggregate must contain reactive forms of
silica, along with a sufficient amount of alkalis, and
abundant moisture. Just because an aggregate
contains ASR reactive phases, and most do, it
does not mean that deleterious ASR gels will form
in the concrete. Also discussed will be Alkali
Carbonate Reactions and Pyrrhotite Reactions.
The presentation will provide details of the history
of Pennsylvania’s ASR specification development
and revisions, beginning in the early 1990’s and
until the present day. Results from the widespread
testing of Pennsylvania’s aggregates with the
currently approved test standards are presented
along with issues of the repeatability of these
test methods. Challenges with durability and
constructability due to high levels of mitigation
are discussed, along with an outline of plans to
address the current limitations that have been
encountered.
The Engineer’s Workshop: Hands-On Flatwork
Durability (8 CEU) (Course ECFW2025)
Step out of the office and onto the slab. This
special session gives specifiers a firsthand look
at what certified concrete finishers must know
to deliver durable, high-quality work. Learn the
practical realities of concrete placement, finishing
techniques, curing methods, mix behavior, and
jobsite challenges. See how your specifications
play out in the field—and how to write them better.
Gain valuable insight that bridges design and
execution, helping you build stronger relationships
with contractors and stronger concrete on every
project.
Zero Defects Concrete (1 PDH)
This presentation provides information o materials
used in the production of concrete, including
cementitious materials, aggregates, and various
admixtures which aid in the placement and
finishing of concrete. Also discussed are selecting
the proper mixes for the applications, weather
considerations, proper jointing of concrete, curing
and strength development, and common problems
that occur in concrete.
