RE: Submittal Documents
Please find enclosed our submittal documents for the above referenced project.
Big D will guarantee strength according to ASTM C94 only if field sampling has been
accomplished per ASTM C172 and ASTM C31 and the laboratory testing also fully
complies with ASTM C39 and ASTM C1077. Big D Concrete will not guarantee strength
for the mix designs submitted if the following conditions occur : 1.) the concrete
temperature is below 55 degrees or above 95 degrees, 2.) the design plastic properties –
“slump” is exceeded by additional water added on site, 3.) the concrete is not placed
within 90 minutes of the batch time. It is the purchaser’s responsibility to inform Big D
Concrete of any planned or unplanned delays during the pouring process so deliveries can
be coordinated. The concrete temperature requirements stated above shall not supersede
any more restrictive temperatures specifications. For concrete ordered during hot
weather, Big D Concrete will require the purchaser to order ice to meet concrete
temperature specifications. All concrete shall be placed and cured according to the
appropriate ASTM guidelines and recommendations for hot and cold weather concreting.
Test cylinders must be cured per ACI 301, section 1.6.3.2.d for Big D Concrete to
guarantee strength. It will be the purchaser’s responsibility for precautions to protect the
placed concrete from excessive heat, wind, rain, hail, and low humidity per ACI 305
guidelines. Big D Concrete will not take responsibility for concrete defects relating
to the finishing process, (cracking, scaling, dusting, delamination, discoloration, etc.
This also includes proper preparation, compaction, and wetting of the subgrade or
forms - especially during hot weather, as well as the proper placement of rebar and
control joints.
During periods of cold weather, it is the purchaser’s responsibility to protect the concrete
from freezing during the initial curing period – the first 7 days.
Big D Concrete will not be responsible for any concrete rejected for non-compliance
of concrete temperatures for not ordering or declining temperature control
measures – hot water in cold temperatures or ice during excessive heat.
Big D Concrete emphasizes the need to avoid free fall of concrete which result in the
loss of air.
For pumped concrete with different boom configurations, hose extensions, line
reductions, and free fall distances which are all out of Big D Concrete’s control, Big
D Concrete will not be responsible for any loss of air content or costs associated with
either rejected fresh concrete or the removal and replacement of hardened concrete
due to the non-compliance of required air content or placing concrete outside of the
specified slump range or exceeding the time limitations of concrete placement.
Per ASTM standards, Big D is requesting the testing lab use 6 x 12 cylinders due to
the 1” aggregate.
Thank you for the opportunity to submit these documents. We are requesting a
copy of the approved submittal. Please order by our designated mix.
We are also requesting Big D Concrete be added to the list of names receiving copies
of testing laboratory information for this project.

Technical Data Sheet
Riteks™ Construction Admixture Chemicals
General Description
SYAD™ 75 is a retarding admixture recommended for all concrete where extended
setting characteristics, particularly in hot weather are desired. SYAD 75 delays time
of set to accommodate long haul times, or facilitate placement and finishing during
hot weather concreting.
Primary Applications
SYAD 75 was designed to be used where an economical and effective retarding is
required to offset the accelerating effects of high ambient temperature concreting.
SYAD 75 will delay initial set times allowing proper placement and finishing without
cold joints in hot weather conditions.
Features / Advantages
• Delays setting characteristics
• Improves workability and finishability
• Excellent retarding properties
How to Use / Dosage
Mixing: SYAD 75 should not come into contact with dry cement or other admixtures
until they are mixed.
Dosage: Rates will vary depending on the materials used, ambient conditions and
the requirements of a specific project. For best results, add SYAD 75 to the water
and aggregate mix at between 1.5-3 fl. oz of 100 lbs. of cementitious materials. Due
to variations in concrete materials, job site conditions and applications, dosages
outside of the recommended range may be required. In such cases, contact your local
Riteks Construction Chemical Representative.
Note: SYAD 75 does not contain calcium chloride or any chloride-based components
and is non-corrosive to reinforced, galvanized floor/roof systems or prestressing steel.
