The attached concrete mix designs utilizing the appropriate ASTM
C-33 or ASTM C-330 aggregate are proposed for use on the above
referenced project for ready-mixed concrete to be furnished by
TXI.
To ensure that the cor=ect mix is delivered to your project,
please order by the mix design number which appears in the upper
left hand corner of the mix design.
Texas Industries certifies that the above mix designs, when
ordered by specified design identity, and delivered by TXI, will
meet or exceed the indicated design strength at the designated
ag~ when tested in accordance with the applicable and current
ASTM Standards C 31, C 39, C 78, C 172, C 293, applicable
provisions of C 94, and evaluated in accordance with applicable
provisions of ACI Building Code.
TXI would like to be included on your mailing list to receive all
test reports. ASTM C 94 entitles a manufacturer to receive
copies of all test reports when strength of concrete is used as a
basis for acceptance.
Please contact us if you have any questions or require any
additional information. Please notify TXI of approval of the
proposed mix designs prior to their use. Failure to notify us
prior to first placement shall'constitute acceptance. To ensure
that the proper mix designs are ordered, please send a copy of
this letter, after approval, to the above referenced project to
be used by the person ordering the concrete for this job.
Sincerely,
Texas Industries

Paragraph 5.5 of ACI 318-89 provides that as data becomes
available during construction, the amount by which (F'cr) must
exceed the specified value of (F'c) may be reduced, provided:
(a) 30 or more test results are available and average of
test results exceeds that required by Section 5.3.2.1,
using a standard deviation calculated in accordance
with Section 5.3.1.1, or
\
(b) 15 to 29 test results are available and average of test
results exceeds that required by Section 5.3.2.1, using
a standard deviation calculated-in accordance with
Section 5.3.1.2.
The required average'compressive strength has been calculated
using a standard deviation calculated in accordance with
ACI 318-89 Section 5.3.1.1 or Section 5.3.1.2 and is the larger
value of these calculations:
F'cr = F'c + 1.34(SD)
= 4200 + 1.34( 589.9)
= 4990
F'cr = F'c + 2.33(SD) - 500

Daravair 1000
AIR-ENTRAINING ADMIXTURE ASTM C 260 AASHTO M 154
Description
Darovai~-1000 is a liquid airentraining
admixlure that provides freeze-thaw
resistance, yield control, and finishability
performance across the full range of concrete
mix designs. Daravair-1000 is a clean,
light-orange produd designed to generate
specificationcluali air systems. Based on a
high-grade saponiYied rosin brmulation,
Daravair-1000 is chemically similar to
vinsol-based products, but with increased
purity and supply dependability.
Uses
Daravair-1000 may be used wherever the
purposeful entrainment of air is required by
concrete specifications. Formulated to r-
form across the entire spectrum of pr~u~ion
mixes, Daravair-1000 generates quality,
freeze-thcr,,v resistant air systems in concrete
conditions that include the following:
· Low Slump
· Paving
· Central Mix
· Extruded Slip Form
· Mixes Containing Hot Water and
Accelerators
* Precast
· High Cement Factor
', Fly Ash and Slag
· Superplasticizers
· Manufactured Sands
Air-entraining Action
Air is incorporated into the concrete by the
mechanics of mixing and stabilized into mil-
lions of discrete semi"rnicroscopic bubbles in
the presence of a specifically designed air-
antraining admixture such as Daravair-1000.
These air bubbles act much like flexible ball
bearings increasing the mobility, or plasticity
and workability of the concrete. This can
rmit a reduction in mixing water with no
'oFo~ of, slump. Placeability is improved.
Bleeding, plastic shrinkage and segregation
are minimized.
Through the purposeful entrainment of air,
Darovair-1000 markedly increases the
durability of concrete to severe exposures
particularly to freezing and thawin . It has
also demonstrated a remarkable cr~oility to
impart resistance to the action of frost and
deicing soils as well as sulfate, sea and
alkaline waters.
Compatibility with Other Admixtures
Daravair-1000 is fully effective and
compatible in concrete with other admixtures.
EACH ADMIXTURE, HOWEVER, SHOULD
BE ADDED TO THE CONCRETE
SEPARATELY.
Addition Rate
There is no standard addition rate for
Daravair-1000. The amount to be used will
depend upon the amount of air required For
ob conditions, usually in the range olc 4 to
8%. Typical factors which might influence the
amount of air-entraining admixture required
are, temperature, cement, sand radation,
and lhe use of extra fine materiL~s
such as fly ash and microsilica. Typical
Daravair-1000 addition rates range from
3/4 to 3 fluid ounces per 100 Ibs.
(50 to 200 mL/100 kg) of cement.
The air-entraining capacity of Daravair-1000
is usually increased when other concrete
admixtures are contained in the concrete,
particularly water-reducing admixtures and
water-reducing retardors. This may allow up
to a two-thirds reduction in the amount of
Daravair-1000 required.
Mix Adjustment
Entrained air will increase the volume of the
concrete making it necessary to adjust the
mix pro rtions to maintain the cement Factor
and yie dJ~. This may be accomplished by a
reduction in water requirement and
aggregate content.
Dispensing Equipment
A complete line of accurate automatic dis-
pensing equi ment is available. These dis-
pensers can ~ located to discharge into the
water line, the mixer, or on the sand.
Packaging
Daravair-1 OOO is available in bulk, delivered
by metered tank trucks and in 55 gallon
(210 L) drums. Daravair-1000 contains no
flammable ingredients. DARAVAIR-1000
WILL FREEZE AT ABOUT 30°F (-1 °C) BUT
ITS AIR-ENTRAINING PROPERTIES ARE
COMPLETELY RESTORED BY THAWING
AND THOROUGH MECHANICAL
AGITATION.

WRDA® wit Hycol
Water-Reducing Admixture
ASTM C 494 Type A
DESCRIPTION:
WRDA® with HYCOLT~4 admixture is an aqueous solution of
complex organic compounds, one of which is HYCOL,
a patented portland cement hydration control agent.
WRDA with HYCOL is a ready to use low viscosity liquid
which is factory promixed in exact proportions to minimize
handling, eliminate mistakes and guesswork.
WROA with HYCOL contains no calcium chloride. 1 gal. weighs
approximately 9.6 Ibs. (1 I= 1.15 kg).
USES:
WRDA with HYCOL produces a concrete with lower
water content (typically 8 to 10% reduction), greater
plasticity and higher strength. It is used in ready mix plants,
block and concrete products plants, in lightweight and pre-
stressed work.. . wherever concrete is produced. tt is also
used by contractors in field equipment such as job site
plants and pavers.
ADVANTAGES:
Most calcium-chloride-free water-reducing admixtures on
the market today produce some significant degree of set
retardation. Minimal extension of set"ring time has been
experienced in field concrete containing WRDA with HYCOL
Under closely controlled laboratory conditions, the retardation
observed with the addition of 3 fl. oz. of WRDA with HYCOL per
100 Ibs. (190 ml/100 kg) of cement is in the range of 15 to 20
minutes, well within the limit of the accuracy of the method of
test. It is through the action of the patented HYdration COntroL
(HYCOL) agent in the admixture that its effect on the setting
time of concrete is reduced to an insignificant degree.
The use of WRDA with HYCOL produces a plastic concrete that
is more workable, easier to place, more pumpable, and has
better finishability than plain or other admixtured concrete. In
the hardened state, WRDA with HYCOL concrete has higher
compressive and fiexural strengths at all ages than untreated or
conventionally admixtured concrete.
The greater degree of plasticity achieved, compared with
conventional water-reducing admixtures, allows improved
finishability.
HYDRATION CONTROL:
HYCOL acts to optimize the rate and degree of hydration
Of the portland cement in the concrete. This optimization gives
concrete strength advantages at all ages without appreciably
altering its setting time.
WRDA with HYCOL also acts as a dispersing agent and lessens
the natural interparticle attraction between cement grains in
water. This reduces their tendency to clump together, making
the mix more workable, placeable and finishable with less
water.
The combination of water reduction and controlled hydration
by HYCOL optimizes the rate of formation of the gel, the paste
or binder that "glues" the concrete aggregates together. This
controlled rate of gel formation adds to the water retention and
internal cohesivehess of the mix, reducing the bleeding and
segregation while increasing or improving the workability,
placeablity and finishability of concrete.
FINISHABILITY:
Finishers have stated that the cement paste, or mortar, in WRDA
with HYCOL admixtured concrete has improved trowelability.
The influence of WRDA with HYCOL on the finishability of lean
mixes has been particularly noticeable, Floating and troweling,
by machine or hand, easily imparts a smooth, close tolerance
surface with less machine time and labor.
ADDITION RATE:
Excellent results are obtained using addition rates of 3 to 6 ft. oz.
of WRDA with HYCOL per 100 Ibs. (190 - 375 mill[X] kg) of
cement. In some cases it may be necessary to slightly modify
the addition rate due to variations In cement, aggregate or
other job conditions.
DISPENSING EQUIPMENT:
A complete line of accurate dispensing equipment is
available. WRDA with HYCOL may be introduced to the
mix on the sand or in the water.
COMPATIBILITY WITH OTHER ADMIXTURES:
WRDA with HYCOL is compatible in concrete with all air-
entraining admixtures such as DAREX II AEA®. Due to a
synergistic effect of WRDA with HYCOL, the quantity of
DAREX II AEA admixured in concrete may be reduced by
about 25%. By combining the separate effects of air entrain-
ment and dispersion, the water requirement of concrete may
be reduced up to 15%. EACH ADMIXTURE SHOULD BE ADDED
SEPARATELY. While WRDA with HYCOL contains no calcium
chloride, it is compatible with calcium chloride in concrete
mixes. Again, each should be added separately.
PACKAGING:
WRDA with HYCOL is available in bulk, delivered by metered
tank trucks, and 55 gal. (210 I) drums. WRDA with HYCOL
contains no flammable ingredients. IT WILL FREEZE AT ABOUT
28°F (-2°C), BUT WILL RETURN TO FULL STRENGTH AFTER THAWING
AND THOROUGH AGITATION.

DARATARD i7
I
~.~,:
Initial Set Retarder ' ·
ASTM C494 Type B & Type D
DESCRIPTION:
DARATARD®-17 admixture is a ready-to-use aqueous
solution of hydroxylated organic compounds. Ingredients
are factory premixed in exact proportions to minimize
handling, eliminate mistakes and guesswork. One gallon
weighs approximately 10.2 Ibs.
USES:
DARATARD- 17 retards the initial and final set of concrete. At
the usual addition rate of 3 ft. oz./lO0 Ibs. cement it will
extend the initial setting time of portland cement concrete
by 2 to 3 hours at 70°F. DARATARD-17 is used wherever a
delay in setting time will insure sufficient delivery, place-
ment, vibration or compaction time, such as in:
· Hot Weather Concrating
· Transit Mix Concrete
· Prestressed Concrete
DARATARD-17 is also used in special applications, as in
bridge decks where it extends plastic characteristics of the
concrete until progressive defkflection resulting from in-
creasing loads is completed.
WATER REDUCING PROPERTIES:
Along with set retardation, DARATARD-17 provides water
reduction (typically 8 to 10%) in a concrete mix. This water
reducing action of DARATARD- 17 produces greater plastic-
ity and workability in the fresh concrete and the strength
and permeability of the hardened concrete are measur-
ably improved. DARATARD-17 is designed for use on jobs
where high temperatures or extended setting times are the
prime factors. It is recommended only when the primary
purpose is to delay and control the setting time of concrete.
When time and temperature are not major considerations,
Grace Construction Product's water reducing admixtures
such as WRDA® with HYCOLTM should be used.
COMPATIBILITY WITH OTHER ADMIXTURES:
DARATARD-17 is compatible in concrete with all commer-
cial air antraining admixtures, such as DARAVAIR®. Due to
the slight air antraining properties of DARATARD-17, itself,
the addition rate of DARAVAIR may be reduced by about
25%. By combining the separate effects of air entrainment
and dispersion, the water requirement of concrete may be
reduced up to 15%. EACH ADMIXTURE SHOULD BE ADDED
SEPARATELY.
ADDITION RATES:
Addition rates for DARATARD-17 will range from 2 to 5 fluid
ounces per 100 Ibs. of cement. The amount to be used will
depend upon the degree of retardation required under job
conditions. Longer setting times or higher temperatures will
require higher addition rates. Conversely, the addition rate
will be lower for shorter extensions of time.
DISPENSING EQUIPMENT:
A complete line of accurate, automatic dispensing
equipment is available. DARATARD-17 may be introduced
to the mix with the sand or with the water.
PACKAGING:
DARATARD-17 is available in bulk, delivered by metered
tank trucks, and 55-gallon drums. It contains no fiammable
ingredients. DARATARD-17 WILL FREEZE AT ABOUT 28°F, BUT
WILL RETURN TO FULL STRENGTH AFTER THAWING AND
THOROUGH AGITATION.
ARCHITECTS' SPECIFICATION FOR
CONCRETE RETARDING ADMIXTURE:
Concrete shall be designed in accordance with ACI
Standard Recommended Practice for Selecting Propor-
tions for Concrete (ACI 211.1-8i).
The set retarding/water reducing admixture shall comply
with ASTM Designation C 494, Type D admixture, and shall
be DARATARD- 17, as manufactured by Grace Construction
Products, or equal. Certification of compliance shall be
made available on request. It shall be used in strict accor-
dance with the manufacturer's recommendations.
The addition rate shall be adjusted to produce the specified
retardation of the concrete mix at all temperatures.

Daracem lO0
SUPERPLASTICIZER ASTM C 494 TYPE F & TYPE G
scrlption:
Daracem®-I O0 is an aqueous solution of
chemical dis rsonts combined wiih other
chemicals w~ich increase its beneficial effects
on the qualily and plasticity of a concrete
mix.
Daracem-1 O0 is the first high range water
reducer specially formulated br extended
slump life. Conventional superplasucizers
normally provide only 25 to 45 minutes of
slump increase before the concrete begins to
lose workability. Daracem-100, however,
extends the time span of the slump increase
up to twice as long or longer.
Chemical Action:
Daracerml O0 neutralizes the surface charges
on cement particles causing extreme disper-
sion, resulting in complete, efficient cement
hydration which, in turn, greatly increases
strength development.
Uses:
Daracem-t 00 provides improved slump
retention in flowable concrete. It is ideal for
tow water/cement ratio concrete desi ned
for high ea compressive and flexur~
strengths w~ exceptional workability and
flow characteristics. Because of its unique
ability to draw maximum effect from the
cement content of a mix, it frequently gives
performance with a 'F pe I cement
corn rable to that otYap Type III cement. It
can ~ used in precast/prestress work to
reduce the high energy requirement of exter-
nal heat for accelerated curing. Daracem-
100 helps to solve difficult placeabili
problems such as dense rebar netvvo~ or
constricted forms and job conditions requiring
that the concrete be transported or pumped
for long distances. A Daracem-100 mix flows
easily into forms and around reinforcing steel.
Even at high slump, the concrete consolidates
well without
segregation. Daracem- 1 O0 concrete reaches
stripping stren ths quickly and finishes easily
without the sti~iness, tearing and surface
drying characteristics sometimes experienced
with other high range water reducers.
Addition Rate:
Daracern-1 O0 can be added at variable
addition rates to suit job requirements. The
normal dosage range is 5-20 oz per
100 Ibs (325-1300 mL/100 kg) of cement.
In the lower range, Daracem-100 meets the
requirements for an ASTM C 494 Type F
water-reducing, high range admixture and at
the upper range for a Type G water-reduc-
ing, high range and retarding admixture.
Varying addition rates may give added
slump variances to match placement needs.
Should job conditions require more than rec-
ommended addition rates, please consult
your Grace representative.
Compatibilily:
Daracem-1 O0 treated concrete should use a
Wood Resin air-entraining agent, (such as
Daravair* and Daravair-1000) or a tall oil
derivative air entrainer (such as Darex® II AEA)
for proper air void parameters to provide
resistance against freezethaw attack.
Because of the high dispersion of
Daracem-100, the use of 'F pe A & D admix-
tures (water reducers/retarYYeFrs)are usually
not necessary. Prei~sting of the concrete
should be performed to optimize dosage
rates, determine mix design and selting
characteristics.
Admixtures should not contact each other
before entering the concrete. Pretesting to
determine optimum addition rates will
benefit performance.
Packaging:
Daracem-1 O0 is available in bulk, delivered
by metered tank trucks, and in 55 gallon
(210 L) drums.
Daracem-100 contains no fiammable
ingredients.
It will begin to freeze at 32 F (0 C) but will
· reconstitute to full strength after thawing and
agitation. In storage and for troublefree dis-
pensing, Daracem-100 should be main-
rained at temperatures above 40 F (4 C).
