MEMORANDUM
DATE:February 3,2005
TO:Lawrence P.Fabbroni,P.E.
and the Commissioners,Staff and Associates
of the Ithaca Area Wastewater Treatment Plant
FROM:Peter D.Novelli,P.E.
RE:Report on Extended Alkali Silica Reaction
This will summarize the results of the extended ASR tests that we performed on concrete
samples from the Plant.
As we discussed with the Committee and described in our report of September,2003,Alkali
Silica Reaction (ASR)was identified in the concrete structures at the Plant.Briefly,ASR causes
expansion and extensive cracking of the concrete and can lead to eventual deterioration of the
structures.
We recommended that the next step should be a group of accelerated ASR tests performed on a
group of concrete cores taken from different structures at the plant.The cores were sent to
American Engineering Testing,Inc.at St.Paul,Minnesota.
The concrete samples consisted of six cores measuring 3.25 inches in diameter at representative
areasofthe Plant (see attachedLayoutPlan).Testingbegan on October 14,2004 at the
laboratory in St.Paul.Testing was extended beyond the initial one month duration because the
rate of expansion had not tapered off.Testing was continued for a total of 94 days and then
stopped.
As you can see on the attached report from American Engineering Testing,at 94 days the
expansion of the cores ranged from 0.21 percent to 0.56 percent,with an average of 0.41 percent.
This means that a core taken through a 10-inch concrete wall would have expanded an average of
1/16 inch in length,and also would have expanded in diameter (although this is not measured in
the test).Expansion of the amount is sufficient to exceed the compressive and tensile strength of
concrete and cause cracking and failure.The presence of reinforcing steel (rebar)in this
structure helps to control the deformations..
Looking at the graph in the report,one can see a steady increase in expansion.
1
L
--..In my opinion,the test results indicate that the concrete materials used in the Plant are not highly
or rapidly reactive to ASR (or we would have seen a sharp initial increase in expansion).
However,the rate of expansion is significant and I expect that it will continue,possibly fordecades.
The problem with this slight expansion is that concrete is a rigid material and,especially at
comers,slab joints and wall joints,it does not respond well to expansion;it cracks.These
networks of cracks not only weaken the strength of the concrete,but they allow corrosive liquids
and oxygen to penetrate into the concrete and initiate corrosion of the rebar.When rebar
corrodes,it expands in volume and cracks the concrete around it,accelerating the cycle ofdeterioration.
If you will refer back to my October,2003 report,you will see photos of typical ASR cracking.
In that report,I explained the following:
ASR occurs when certain silica-containing (siliceous)stone aggregates react with the
high pH Portland cement (in chemistry terms,high concentration of hydroxyl ions).The
reaction results in formation of a hygroscopic gel (meaning it has an affinity for water).
In the presence of moisture,the gel will absorb water and expand.This expansion can
generate pressures in the range of 700 to 800 pounds per square inch (psi,5-6 Mpa
[11j),and this exceeds the tensile strength of standard structural concrete,normally in
the range of 300 to 400 psi.This causes the concrete to crack (see Figure 2).
Concrete that is confined by rebar may have much higher tensile strength,depending on
the orientationof the rebar.Thus,sometimes--but not always --the effects of ASR are
mostly limited to the concrete outside the rebar grids.Depth of ASR cracking can be
verified by coring the concrete element in question.
The best way to control ASR is when the concrete is being batched,by checking the
aggregate for silica-containing minerals,and by knowing the true alkali content of the
Portland cement.Both of these may vary over time and with suppliers.
We do not now have the option to control the batching of the concrete,obviously,so what
options exist to help control this deterioration?After the ASR process is initiated,one way to
control ASR is to control its water source.ASR cannot proceed without water.Obviously,it is
difficult to accomplish this in water-retaining structures such as wastewater treatment plants.
However,the black coal-tar epoxy coatings inside the tanks help to prevent water from
penetrating the concrete.As part of overall plant repair procedures,the tank walls could be
prepared and resurfaced with appropriate coatings.
Another much more experimental possibility is the concept of lithium-salt injection to the
concrete.Lithium salts are now being used as an admixture in concrete to prevent ASR (see
attached data sheets from Masterbuilders).Basically,the lithium salts react with the reactive
silica in the concrete faster than the alkalis in the cement,and form lithium silica gel that is not
destructive to the concrete.Thus,it interrupts the ASR process.There has been some
experimentation with diffusing these salts,in aqueous solution,into existing ASR-damaged
concrete.Sometimes electric current is used to draw the lithium-salt ions into the concrete.
It is my opinion that lithium injection is still too experimental to use in large-scale fashion at the
IAWWTP,however a small pilot project could be started and observed.Based on the results of
that,further actions could be taken if warranted.
Last,I believe that existing visible concrete deterioration should be carefully repaired and then
maintained.This can only help to prolong the life expectancy of the structures.These repairs
were outlined in my October,2003 report.

INTRODUCTION
This report presents the potential reactivity testing of concrete cores taken from the Ithaca,New
York Waste Water Treatment Plant.The cores were 3.25 inches in diameter by up to 12 inches
in length.The samples were submitted by Shawn Randall with Novelli Engineering on
September 9,2004.The scope of our work consisted of preparing the core samples,placing the
specimens into the test environment and documenting the length change of the cores in general
conformance to the procedure described in ASTM:C1260,section 8 (as modified above),and
preparing a written report detailing the results of our testing.
CONCLUSION
Based on the results orour testing and experience it is our opinion the folJowing conclusions are
appropriate:
I.The average expansion at 14 days of immersion in a 4%sodium hydroxide solution was
determined to be 0.06%.The measurements ranged from 0.04%to 0.09%,however one
core experienced an unexplained negative length change of -0.03%.
2.The average expansion at 45 days was detenl1ined to be 0.22%.The measurements
ranged from 0.08%to 0.34%.
3.The average expansion at 94 days was detem1ined to be 0.41 %.The measurements
ranged from 0.21 %to 0.56%.
4.We expect the concrete to suffer from additional alkali-silica reaction.The cores showed
no indication of a slowing of expansion up to 94 days of testing.

TEST RESULTS
The testing was perfol11ledon October 14,2004 and subsequent dates in general accordance with
ASTM:C1260,as m.odified above.The test results are as follows:
*The percent expansion is based on the initial gage length of each core.
**These average values do not include core sample #3.
PROCEDURES
The core samples were trimmed and gage bolts were installed in each end using epoxy cement to
alJow for measurement in the 10 inch gage length apparatus.Initial readings were taken at 24
hours.The specimens were placed in the container with sufficient water to totally immerse
them.Zero readings were taken after 24 hours in water at 1760 F.After the zero reading,the
specimens were placed in the 4%NaOH solution at 1760 F for the remainder of the testing.
Intennediate and final readings were taken on the days noted in the table above.
Intermediate and final readings were based on the percent expansion from the zero day reading.
REMARKS
The test samples will be retained for a period of thirty days from the date of this report.Unless
further instmctions are received by that time,the samples will be discarded.The test results
represent specifically the samples tested.

1.DESCRIPTION:
The HEY'DI SPECIAL SYSTEM is a
combination of cementitious and silicate
based materials used on negative side
surfaces to seal and stop leakage caused
by hydrostatic pressure.HEY'DI
SPECIAL SYSTEM is a 5 coat,three
component system consisting of two
po'Miersand a liquid.HEY'DI POWDER
No.1 is designedfor use as the undercoat
and overcoat of the 'sealing
system.HEY'DI POWDER X is a dry
po'Mier that hardens in seconds when
exposed to ~ter.HEY'DI SEALING
LIQUID penetrates through HEY'DI
POWDERNo.1 and HEY'DI POWDER
X into the capillaries of the substrate.
There,it reacts with moisture and the
constituents of the substrate to form
crystals.While moisture is present,the
crystallizationprocess will continue for
approximately six months.HEY'DI
SPECIALSYSTEMis a dark cementgray
color,and is not intended as a decorative
fmish.
2.USES:HEY'DI SPECIAL SYSTEM
waterproofu leaking and weeping concrete
or masonry from the negative side to
protect against hydrostatic water pressure.
It is applied to interior or exterior walls
below grade,slabs on grade,foundations,
basements,swimming pools,reservoirs,
tunnels,dry docks,and other areas where
leakage is encountered.Properly applied,
HEY'DI SPECIAL SYSTEM becomes an
integral part of the structure and cannot
be separated from the surface by water
pressure.HEY'DI SPECIAL SYSTEM is
not designed to be used as a wearing
surface.Horizontal surfaces subject to
vehicle or heavy foot traffic must be
covered with a protective topping.For

5.3 F1oorlWall Joint Leakage -
A.Cut an area approximately 'h inch
deep a minimum 3 to 4 inches up
the wall,and 3 to 4 inches onto the
floor.
B.Use HEY'DI POWDER X to stop

D.Following cure,mix a mortar of a
1:3 ratio of HEY'DI SB
BONDING AGENT and potable
water with a 1:3 ratio of cement
and sand,and level the area with
the floor surface.
6.APPLICATION TECHNIQUES:It is
important that the first four steps follow
each other in quick succession.Rubber
gloves must be worn for each step of the
application.Gloves and brushes must be
washed in clean water immediately after
eah step is completed.For one man
working alone,only 10 square feet should
be treated at one time.
Saturate substrate with potable water
before application.Surface must be wet,
with no running or standing water.
Moisture must be present in the surface
to start the crystallization process.
Step 1:Mix potable water with a small
amount of HEY'DI POWDER
No.I to make a thick slurry.Load
the bristles of a cement masons's
brush and quickly work the slurry
into the surface to fill all pores and
voids.
Step 2:Rubber gloves must be worn.
Immediately hand rub HEY'DI
POWDER X well into the wet area
until the surface is dry.This
application should not be more
than 1/32 inch thick.
Step 3:Use a clean brush,and
immediately follow with a brush
coat of HEY'DI SEALING
LIQUID.
Step 4:While the HEY'DI SEALING
LIQUID is still wet,follow
immediately with another coat of
HEY'DI POWDER NO.I slurry
applied in the same manner as
Step 1.
Step 5:Wait 30 to 60 minutes,and apply
the final coat of HEY'DI
POWDER NO.I in the same
manner as Step 1.
Note:A decorative appearance may
be achieved in Step 5 by
substituting HEY'DI K-ll WHITE,
or other cementitious coatings such
as TAMOSEAL,CONCRETE
FINISHER,or TAMMS SBC for
the HEY'DI POWDER No.I
Upon completion of the five steps,protect
the surface from rain,hot sun,or wind,
and freezing or frost for a minimum 48
hours.
To produce an uninterrupted waterproof
membrane,apply HEY'DI SPECIAL
SYSTEM to the base slab and allow to
dry 24 hours.Then apply the HEY'DI
SPECIAL SYSTEM to the vertical
surfaces and carry the application out onto
the slab at least 12 inches.
If a liquid polymer decorative [mish is to
be applied,allow 7 days curing time for the
HEY'DI SPECIAL SYSTEM.Do not use
lime based products over HEY'DI
SPECIAL SYSTEM.
7.APPROXIMATE COVERAGE:HEY'DI
POWDER No.1,used as a slurry,is
applied at 0.14 Ibs per sq ft per coat.Total
3 coat process requires a minimum of 0.44
Ibs per sq ft.HEY'DI POWDER X,applied
dry at 0.28 Ibs per sq ft.HEY'DI
SEALING LIQUID,used as received,at
60 sq ft.per gallon.
8.CLEAN-UP INSTRUCI10NS:Clean all
mixing and application equipment with
water immedatiately after use.Clean all
splatteror spills with water before material
sets.HEY'DI SPECIAL SYSTEM is a
cementitiousproduct and if allowed to dry
on the surface,removal becomes very
difficult.
9.CAUTIONS:HEY'DI POWDER No.I
and HEY'DI SEALING LIQUID are
components of the HEY'DI SPECIAL
SYSTEM,and cannot be used alone.Do
not retemperHEY'DI POWDER No.1 or
HEY'DI POWDER X.Do not apply to
frozen or frost filled surfaces or when
temperature is below 40 degrees F,or
expectedto fall below 40 degrees F in 48
hours.Do not apply in temperaturesabove
90 degreesF.Do not use as a trafficbearing

SPEED CRETE RED LINE
Fast Setting Patching Material
1.DESCRIPTION:SPEED CRETE
RED LINE is a fast setting,ready-to-
use,cement based concrete and
masonry patching compound that
requires only potable water for
mixing.It achieves initial set in
8 to 10 minutes,and final set within
20 minutes.After initial set,
SPEED CRETE RED LINE may be
shaved to conform to the contours of
the surrounding surface.Properly
mixed and applied,SPEED CRETE
RED LINE develops high strength,
tenacious bond,and excellent
resistance to freeze-thaw and
weathering.
2.USES:SPEED CRETE RED LINE
is used interior or exterior,above or
below grade,on vertical,overhead,
and horizontal surfaces without
forming.SPEED CRETE RED LINE
is used for the patching,repair,
restoration,and cosmetic
reconstruction of curbs,sidewalks,
expressways,bridges,formed and
precast concrete ceilings,panels,
walls,and concrete pipe.
3.LIMITATIONS:Use SPEEDCRETE
BLUE LINE for patching areas
continuously exposed to moisture.
Use SPEED CRETE GREEN LINE,
a semi-flowablepatching material,for
patching horizontal concrete surfaces.
Do not mix with SPEED CRETE
WHITE LINE.0)co

g:selected aggregates,and specific~chemical additives.SPEED CRETE
0 0 RED LINE,when combined with the
~81 correct amount of water,undergoes a
~~chemical "hyper hydration"to
::2:z produces a stable,low permeability,~~cementitous matrix.
5.SURFACE PREPARATION:Surface
must be structurally sound,clean,free
of loose or deteriorated concrete,dust,
dirt,and other contaminants.Undercut
edges of the area to be patched to a
minimum thickness of ~inch (1.9cm).
Clean and prime exposed steel and
reinforcing.When substrate is not
absorptive,abrade as necessary to
ensure proper bonding.
When temperatures are above 35
degrees F (1.7 C),prewet the prepared
area with potable water immediately 8.
before application of the
SPEED CRETE RED LINE.Absorb
excess water and puddles to prevent
dilution of the patching material.
6.MIXING INSTRUCTIONS:SPEED
CRETE RED LINE will require
approximately 5 to 5.5 quarts of potable
water per 50 Ib bag (4.4 -4.8 kg/l),to
achieve the proper mix consistency.
Pour the measured amount of SPEED
CRETE RED LINE,and thoroughly
mix for no more than 60 seconds to a
stiff,no slump,putty-like consistency.
Mix small quantities of SPEEDCRETE
RED LINE in a clean pail with a hand
trowel.Use a rotary mixer with
rubber tip blades for mixing
quantities up to 100 Ibs (45.4 kg).
To fill patches 2 inches (5.1 cm)deep
or greater,add clean,dry Ys inch
(I em)size pea rock or chip stone to
the SPEED CRETE RED LINE.The
mix ratio must not exceed 40 pounds
(18kg)of rock to each 50 pound (22.7
kg)bag or pail of SPEED CRETE
RED LINE.Mixing procedure:1)
start mixer,2)load water,3)load
rock,and 4)load the SPEED CRETE
RED LINE.Mix for no more than 60
seconds.
7.APPLICATION TECHNIQUES:
To ensure complete bond with
the entire surface,force the
SPEED CRETE RED LINE firmly
into the predampened area by hand or
with a trowel.Slightly overfill the
patch,and following initial set,shave
the material to conform to the contour
of the surrounding surface.Always
shave SPEED CRETE RED LINE
toward the common bonding edge
between the patching material and the
existing surface.Cure material using
standard curing practices.For
additional information,contact
Tamms Technical Service Centers.
COLD WEATHER INSTALLATION:
SPEED CRETE RED LINE will
achieve initial set faster than water
will freeze.When temperature is
35 degrees F (1.7 C)or below,do not
prewet area to be patched.
Use heat to eliminate frost in the
substrate,but do not heat surface
above 70 degrees F (21.1 C).Use
warm water for mixing,as cold water
extends the set time.Do not add
antifreeze or accelerators to
SPEED CRETE RED LINE.Do not
use heat after the patching material
has been installed.For additional cold
weather information,contact Tamms
Technical Service Centers.

4.SURFACE PREPARATION:
Surface must be structurally sound,
clean,free of loose or deteriorated
concrete,dust,dirt,and all
contaminants.Vertically cut all edges
of patch area to a minimum thickness
of I inch.Clean and prime exposed
steel and reinforcing.If substrate is
not absorptive,abrade as necessary to
ensure proper bonding.
Prewet prepared area with potable
water immediately before application.
Wipe up excess water and puddles on
horizontal surfaces to prevent dilution
of the GREEN LINE.When
temperatures are 35 degrees F or
lower,do not prewet area,and refer
to Cold Weather Installation
procedures below.
5.MIXING INSTRUCTIONS:
SPEED CRETE GREEN LINE will
require approximately 4 to 4.5 quarts
potable water per 50 Ib bag.Pour a
measured amount of water into a
clean mixing container,add the
measured amount of SPEED
CRETE,and thoroughly mix for no
more than 60 seconds.Initially,the
mixture will seem very stiff,but near
the end of the mixing time,it will
"relax"and achieve a semi-flowable
consistency.Do not add additional
water or retemper.Too much water
weakens the mixture.For large
projects,use a rotary mixer with
rubber tipped blades.Pour the
required amount of water into the
mixer,and add the GREEN LINE.
Mix just long enough to achieve the
proper consistency,but no more
than 60 seconds.Do not mix more
than 100 Ibs at one time.Small
amounts of SPEED CRETE,such as
5 to 10 pounds,may be readily mixed
in a clean pail with a hand trowel.
SPEED CRETE GREEN LINE,
mixed as directed,will achieve initial
set in 6 to 15 minutes,and final set
within 20 minutes.
To fill patches 2 inches deep or
greater,add clean,dry,3/8 inch
size pea rock or chip stone to the
SPEED CRETE.The mix ratio must
not exceed 40 pounds of pea rock
to each 50 pound bag or pail of
SPEED CRETE.
Mixing procedure:Start mixer,load
water,load rock,and then add
SPEED CRETE GREEN LINE.
Mix no more than 60 seconds.
Do not add sand.
Do not use liquids other than
potable water for mixing.
Clean mixing equipment between
batches.
